[Funga • 2025] Samsoniella scoliopterygis (Hypocreales: Cordycipitaceae) • A New Species of Samsoniella on the herald moth, Scoliopteryx libatrix (Noctuoidea: Erebidae), from caves in the British Isles


Samsoniella scoliopterygis  H.C. Evans & J.P.M. Araújo,

in Evans, Fogg, Buddie, Yeap et Araújo. 2025. 
 
Abstract
Samsoniella scoliopterygis (Cordycipitaceae: Hypocreales), pathogenic on the herald moth Scoliopteryx libatrix (Erebidae: Noctuoidea), is described as a new species, based on morphological, ecological and molecular evidence. Infected specimens of this troglophilic moth were recorded from caves, as well as from a copper mine, in southern England (Devon, Norfolk), Northern Ireland (Fermanagh) and the Republic of Ireland (Sligo). The moths were found consistently on the cave floor or rock ledges, rather than on the ceiling amongst the overwintering, healthy moth populations; producing multiple, white or non-pigmented clavae of the cordyceps-like sexual morph. Synnemata of the asexual morph occurred sporadically in situ but were produced consistently in vitro. The ecology and taxonomy are discussed in relation to previous records of entomopathogenic fungi on Scoliopteryx libatrix and other trogloxene moths.

[Fungi • 2026] Pleurocordyceps cornusynnemata • Taxonomy and Phylogeny of Pleurocordyceps (Hypocreales: Polycephalomycetaceae) associated with Ants and Cicadas from Malaysia, including A New Species and New Records

  

Pleurocordyceps cornusynnemata 

in Shahbaz, Mohadden, Rong, Wei et Seelan, 2026.
 
Abstract
Pleurocordyceps is a group of hyperparasites that infects invertebrates, plants, and other fungi. It belongs to the family Polycephalomycetaceae, a newly established family separated from Ophiocordycipitaceae, order Hypocreales which includes several genera such as Dingleyomyces, Paradingleyomyces, Perennicordyceps, Pleurocordyceps, and Polycephalomyces. Pleurocordyceps currently comprises 26 species reported from South American and Asian regions In Asia, Malaysia has diverse forest ecosystems and rich fungal diversity; however, no previous studies have been reported on the occurrence of Pleurocordyceps species. The aim of the study is to explore the Pleurocordyceps diversity tropical rainforests of Malaysia using morpho-molecular analyses. During a fungal survey in Malaysia, fungicolous fungus associated with ants and cicadas nymphs were collected and subjected to morphological and molecular assessments. Two genetic loci—the internal transcribed spacer (ITS) region and the translation elongation factor 1-alpha (TEF-1α) gene—were used to construct both individual and concatenated phylogenetic trees. The study describes a new species, Pleurocordyceps cornusynnemata sp. nov. (BORH/F03651) from an ant, and two new records of P. aurantiaca (BORH/F03651), and P. nipponica (UTHM-CEF003.1) from Diptera and cicada nymph, respectively. These findings expand the knowledge of the geographic distribution of Pleurocordyceps and provide the first baseline data for the genus in Malaysia, thereby improving understanding of the diversity and evolutionary relationships within Polycephalomycetaceae.

[Fungi • 2026] Leptobacillium geminatum • A New Species of Leptobacillium and Additional Records of Simplicillium and Leptobacillium (Ascomycota: Cordycipitaceae) from Sabah, Malaysia



Leptobacillium geminatum

in Shahbaz, De Wint, Rong, Wei, Koid, Fayle, Tan, Abdullah, Palaniveloo et Seelan, 2026.

Abstract
Simplicillium and Leptobacillium are entomopathogenic fungal genera frequently associated with arthropods in tropical ecosystems and considered promising candidates for biological pest control. However, the diversity of these genera in tropical regions, particularly in Malaysia, has not been systematically investigated in the context of their taxonomy and phylogenetic relationships. This study aimed to investigate the taxonomic diversity and phylogenetic relationship of Simplicillium and Leptobacillium using integrated morphological and molecular analyses. During a survey of entomopathogenic fungi conducted in Malaysia from 2022–2023, parasitized insects were collected, including spiders and wasps infected by entomopathogenic fungi. Phylogenetic analyses were performed using concatenated datasets of the internal transcribed spacer (ITS) and translation elongation factor 1-alpha (TEF1-α) gene to construct phylogenetic trees. The study identified one novel species, Leptobacillium geminatum sp. nov., isolated from a spider. In addition, five species are reported here as new records for Malaysia: S. formicae, L. leptobactrum. symbioticum, and L. coffeanum isolated from spiders and S. puwenense, isolated from a wasp. Morphological characteristics together with molecular phylogenetic evidence supported the taxonomic placement of these taxa. These findings represent the first comprehensive documentation of Simplicillium and Leptobacillium species from Malaysia, significantly expanding the known diversity and geographical distribution of these entomopathogenic fungi in Southeast Asia.

[Arachnida • 2026] “The Cordyceps Spider”: Taczanowskia waska sp. nov. (Araneae: Araneidae), A New spider Species and A Novel Case of Mimicry of an Araneopathogenic Fungus (Cordycipitaceae: Gibellula)


Taczanowskia waska
Díaz-Guevara, Bentley & Dupérré, 2026 
 

Abstract 
Herein, we describe a new species of the rare spider genus Taczanowskia Keyserling, 1879 (Araneae: Araneidae), Taczanowskia waska sp. nov. (♀) from the Ecuadorian Amazon. Additionally, we discuss its unique fungal mimicry, comment on Taczanowskia ecology, and provide an updated taxonomic key for females of the genus. The importance of this discovery extends well beyond the description of a novel taxon, representing the first reported case of Arachnid mimicry of an araneopathogenic fungus. Finally, we discuss the application of citizen science to collecting ecological and biogeographical data on arachnids and its potential use for describing new taxa.

[Fungi • 2026] Gibellula mineiraThe Silent Hunters of Spiders: Discovering A New Gibellula (Ascomycota: Cordycipitaceae) Fungus in the Brazilian Atlantic Forest


Iguarima censoria (Anyphaenidae) spiders
unparasitized and parasitized by Gibellula mineira sp. nov.

Abstract
In tropical forests, there is a high diversity of parasites that use arthropods as resource, particularly arachnids. One of the most frequent groups of spiders’ parasites in tropical forests are fungi of the genus Gibellula, for which a considerable knowledge gap remains in these environments. In this study, we present the description of a new species that infects spiders of the species Iguarima censoria (Anyphaenidae) in the Brazilian Atlantic Forest, Gibellula mineira sp. nov. We also described the prevalence of the new fungal species in the host spider population and evaluated whether the host size influences their probability of parasitism. Morphological and molecular analyses revealed that G. mineira represents a distinct species forming a clade with 100% support of bootstrap and showing a close phylogenetic relationship with Gibellula aurea. The characteristics that distinguish it from other species of the genus include light brown hyphae, white and slightly larger conidiophores, and thinner phialides. We observed a high prevalence of parasitism in this interaction, reaching 25% of the observed I. censoria population. Furthermore, we noted that the cadavers of parasitized spiders are exclusively attached to the underside of leaves, following the typical pattern observed for Gibellula species. Parasitism is more frequent in smaller I. censoria individuals, which is probably associated with thinner cuticles or higher foraging activity in smaller individuals. We suggested that G. mineira is an important natural enemy of I. censoria, directly influencing the population dynamics of this spider and expanding our knowledge of the ecology and biodiversity of araneopathogenic fungi.

Abstract
Four yeast strains representing three novel species were isolated from two sources in Thailand, one from the leaf surface of a tall-stilt mangrove (Rhizophora apiculata, strain DMKU-RG45) and three from the fruiting bodies of wild mushrooms (strains DMKU-TM03, DMKU-SM11, and DMKU-SM28) collected in Thailand. Sequence analysis of the D1/D2 domain of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) region revealed that these four strains differed by 0.87–8.68% and 2.07–13.55% in their nucleotide divergence from their closest described species in the sequences of the D1/D2 domain of the LSU rRNA gene and the ITS region, respectively. In phylogenetic analyses, the strain DMKU-RG45 belonged to the genus Cyberlindnera and was distinct from other recognized species in this genus, whereas the strains DMKU-TM03, DMKU-SM11, and DMKU-SM28 were members of the genus Blastobotrys. However, they were in two different positions, each of which was distinct from closely related species. Based on molecular analyses and phenotypic characteristics, the strain DMKU-RG45 is proposed as Cyberlindnera sirindhorniae f.a., sp. nov. (the holotype is TBRC 19863T; MycoBank No. is MB 858763). The other three strains (DMKU-TM03, DMKU-SM11, and DMKU-SM28) are proposed as two novel Blastobotrys speciesBlastobotrys princeps f.a., sp. nov. is proposed to accommodate the strain DMKU-TM03 (the holotype is TBRC 19382T; MycoBank No. is MB 858764). Blastobotrys siamensis f.a., sp. nov. is proposed to accommodate both strains DMKU-SM11 and DMKU-SM28 (the holotype is TBRC 19380T; MycoBank No. is MB 858765).

Tropical Natural History. Suppl. 8;  

Abstract
Two strains, YSP-519 and YSP-478, respectively representing novel ascomycetous and basidiomycetous yeast species, were obtained from toddy palm inflorescence sap collected in Thailand. The ascomycetous yeast strain YSP-519 was closely related to Metschnikowia agaves CBS 7744T. There were 1.6% nucleotide substitutions (9 nucleotide substitutions and 2 gaps out of 555 nt) in the D1/D2 domains of the LSU rRNA gene and 0.7% nucleotide substitutions (3 nucleotide substitutions out of 454 nt) in the ITS regions. The basidiomycetous yeast strain YSP-478 was closely related to Moniliella pollinis CBS 461.67T. It had 0.5 % nucleotide substitutions (3 nucleotide substitutions out of 554 nt) in the D1/D2 domains of the LSU rRNA gene and 2.0% nucleotide substitutions (9 nucleotide substitutions out of 473 nt) in the ITS regions. Phylogenetic analysis based on the concatenated sequences of the ITS regions and the D1/D2 domains confirmed that the two strains represent two new species. The name Metschnikowia sirindhorniae f.a., sp. nov. is proposed for YSP-519T), and Moniliella princeps sp. nov. is proposed for YSP-478T. The holotypes of M. sirindhorniae and Mo. princeps are TBRC 10642T and TBRC 10641T, respectively and the ex-type are CGMCC 2.6079T and CGMCC 2.6078T, respectively. The MycoBank numbers of M. sirindhorniae and Mo. princeps are MB858878 and MB858879, respectively.

Abstract 
The myrmecophilous hirsutelloid fungi of the Ophiocordyceps unilateralis complex are common in tropical forests around the world. They are known as zombie-ant fungi because they manipulate the behaviour of ants, since infected ants are forced to move to specific sites in the forest, with optimal environmental conditions for the development of the fungus sporocarp or sporome and the release of the spores. Once there, the ants grab to the substrate with their mandibles, die, and their body becomes a source of nutrients for the fungus. Most of the species of the O. unilateralis complex have been described from the Neotropics and the East and Southeast Asia. However, it is likely that there are still many unknown species due to the diversity of their hosts and different specific associations. In this study, we describe six new species of the O. unilateralis complex from western Mexico: Ophiocordyceps camponoti-striati, O. cephalotiphila, O. deltoroi, O. haraveriensis, O. jaliscana, and O. pseudocamponoti-atricipis, based on morphological characters, phylogenetic analyses of DNA sequences (18S, TEF1, RPB1, and RPB2), and ecological data. We found the following host associations: one fungus – one ant, two fungi – one ant, and one fungus – two ants. Furthermore, we confirmed the host species of the ant genera Camponotus and Colobopsis (Formicinae) based on morphological characters and COI sequences, but we also found two species of Cephalotes (Myrmicinae) susceptible to fungal attack, challenging the paradigm that the O. unilateralis complex is a specific parasite of Camponotini (Formicinae) ants. This study provides insights into the evolution and host range of the Ophiocordyceps unilateralis complex in Mexico.

Abstract  
The genus Gibellula (Cordycipitaceae: Hypocreales) comprises species pathogenic on and specific to spider hosts. Here, we report on the occurrence of a novel species infecting cave-dwelling, orb-weaving spiders of the sub-family Metainae (Tetragnathidae) in the British Isles. The new species, Gibellula attenboroughii is described and illustrated and its ecology is discussed; leading to the conclusion that infected spiders exhibit behavioural changes similar to those reported for zombie ants. The hidden diversity of the genus Gibellula in the British Isles is further highlighted based on fungarium records and literature searches.

[Funga • 2024] Metarhizium puerense (Hypocreales: Clavicipitaceae) • A New Species from Yunnan, south-western China


Metarhizium puerense Hong Yu bis, J. M. Ma & Z.Q. Wang, 

in Ma, Wang, Yang, Chen, Li et Yu, 2024. 
 
Abstract
Background: As a genus within the Clavicipitaceae, Metarhizium exhibits rich morphological and ecological diversity, with a wide distribution and a variety of hosts. Currently, sixty-eight species of Metarhizium have been described.

New information: A new species of MetarhiziumM. puerense (Hong Yu bis), was described in Pu'er City, Yunnan Province, south-western China. Based on morphological characteristics and multilocus phylogenetic analyses, Metarhizium puerense was confirmed to be phylogenetically related to M. album, but was clearly separated and formed a distinct branch. In contrast, the host of Metarhizium album was plants and leafhoppers and that lepidopteran larvae were the host of M. puerense. The diagnostic features of M. puerense were solitary to multiple stromata and smooth-walled, cylindrical with rounded apices conidia.

Keywords: Metarhizium, morphology, phylogenetic analyses

[Mycology • 2024] Tuber itzcuinzapotl (Ascomycota: Pezizomycetes: Tuberaceae) • the First Edible Truffle reported from Mexico with Traditional Biocultural Importance


Tuber itzcuinzapotl de la Fuente & Rosales-Rosales,  
 
in de la Fuente, Rosales-Rosales, Martínez-González, Martínez-Reyes, Elizondo-Salas et Perez-Moreno, 2024. 

Abstract
Tuber itzcuinzapotl is described as a new species to science. This species is characterized by its pale brown ascomata, finely granular peridium, pale brown to gray gleba, and 22–52 × 15–40 µm alveolate ascospores. The new species is putatively associated with Pinus patula in conifer mixed forests in the state of Veracruz, located in eastern Mexico. Phylogenetic analysis based on the nrITS region places the new species in the Maculatum clade, closely related, but morphologically distinctive, to T. miquihuanense and T. mexiusanum. The new species consumed by the Nahua people, traditionally named “Itzcuinzapotl”, constitutes the first edible truffle with biocultural importance in Mexico. Macro- and micromorphological characterization, results of phylogenetic analysis, and photographs are presented. Ethnomycological aspects related to the species are also briefly discussed.
 
Key words: biocultural erosion, Ethnomycology, fungi, hypogeous fungi, Mexican truffles, mycorrhizal fungi, traditional knowledge

Tuber itzcuinzapotl de la Fuente & Rosales-Rosales, sp. nov. (Holotype).
A) Fresh ascomata. B) Dry ascomata. C) Peridium hyphal arrangement. D) Hyphae fromsterile veins. E) 3-spored ascus containing 2 mature ascospores showing alveolate ornamentation.
Bar: A–B= 10 mm; C–E=20 μm.

Tuber itzcuinzapotl de la Fuente & Rosales-Rosales, sp. nov.

Diagnosis:—The new species differs from other species within the Maculatum clade by its pale brown ascomata,finely granular peridium, composed of subglobose hyphae, forming pyramid-like structures, clavate terminal cells of11−30 × 6−10 μm, pale brown to gray gleba, and 22−52 × 15−40 μm alveolate ascospores. 

Etymology:—Refers to the name used by the Nahua people to designate this edibles species itzcuinzapotl (itzcuin dog, and zapotl = zapote, a native sweet fruit).

[Fungi • 2023] Paraisaria cascadensis & P. pseudoheteropoda (Ascomycota: Hypocreales) • New Species and New Combinations in the Genus Paraisaria from the U.S.A., supported by polyphasic analysis


Paraisaria cascadensis Tehan, Dooley & Spatafora,
 Paraisaria pseudoheteropoda Tehan & Spatafora,

in Tehan, Dooley, Barge, McPhail et Spatafora, 2023. 
 
Abstract
Molecular phylogenetic and chemical analyses, and morphological characterization of collections of North American Paraisaria specimens support the description of two new species and two new combinations for known species. P. cascadensis sp. nov. is a pathogen of Cyphoderris (Orthoptera) from the Pacific Northwest USA and P. pseudoheteropoda sp. nov. is a pathogen of cicadae (Hemiptera) from the Southeast USA. New combinations are made for Ophiocordyceps insignis and O. monticola based on morphological, ecological, and chemical study. A new cyclopeptide family proved indispensable in providing chemotaxonomic markers for resolving species in degraded herbarium specimens for which DNA sequencing is intractable. This approach enabled the critical linkage of a 142-year-old type specimen to a phylogenetic clade. The diversity of Paraisaria in North America and the utility of chemotaxonomy for the genus are discussed.

Key words: Ascomycota, chemotaxonomy, Cicada, Cordyceps, Cyphoderris, entomopathogen, Ophiocordyceps, Prionus


 Paraisaria cascadensis Tehan, Dooley & Spatafora, sp. nov.
