[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.
