[Fungi • 2022] Lepiota cremea (Agaricales: Agaricaceae s.l.) • A Novel Species of Lepiota sect. Lepiota from Turkey


 Lepiota cremea   O. Kaygusuz 

in Kaygusuz, 2022. 

Abstract
A new species of Lepiota from Turkey, Lepiota cremea sp. nov., is proposed based on morphological characters and phylogenetic analyses of the nuclear rDNA internal transcribed spacer (ITS1-5.8S-ITS2 = ITS) region. The morphological features together with molecular data confirmed both the novelty of this species and its infrageneric placement within Lepiota sect. Lepiota. Lepiota cremea, so far only found in Pinus nigra subsp. pallasiana forest, is characterized by the pale beige basidiomata, subcylindrical to fusiform basidiospores, long pileus covering elements with often nodulose or horn-like bumps. A comprehensive description, illustrations and comparisons with morphologically similar and related taxa are provided.

  Basidiomata of Lepiota cremea (OKA-TR11019, holotype). Scale bars: 10 mm.
 
Lepiota cremea O. Kaygusuz, sp. nov. (Figs. 3‒5)

Diagnosis: — Somewhat similar to Lepiota erminea but differing in pileus colour, which is pale beige, the absence of annulus on stipe, subcylindrical to fusiform basidiospores with higher Q m values, longer pileus covering elements, habitat in the Mediterranean coniferous forests, and distinct ITS sequence.

Etymology: —The epithet of “cremea” refers to the pale beige color of the pileus that characterizes this species.

Abstract
Two new species of Boletopsis, B. macrocarpa and B. tibetana, are described and illustrated from Southwest (SW) China based on morphology, ecology and phylogenetic analyses by the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU). Boletopsis macrocarpa is characterized by big basidiocarps (up to 18 cm in diam), guttulate basidiospores, and the presence of gloeoplerous hyphae in context and growing in pure forest of Pinus yunnanensis. Boletopsis tibetana is characterized by smaller pores (3–4 per mm), the presence of gloeoplerous hyphae in pileipellis, and the growth in forests of Picea. Phylogenetically, the two new species are grouped in two independent lineages nested in Boletopsis. In addition, one sample from Northeast China is temporarily treated as Boletopsis sp. 1 because of the single sample; another Chinese sample from SW China is sister to B. grisea in phylogeny, and it is treated as B. cf. grisea because the morphological difference between B. cf. grisea and B. grisea is indistinct. Furthermore, the main characteristics of Boletopsis species are listed, and a key to accepted species of Boletopsis is provided.

[Cnidaria • 2022] Stylobates calcifer • Carcinoecium-Forming Sea Anemone (Actiniaria, Actiniidae) from the Japanese Deep-Sea Floor: A Taxonomical Description with Its Ecological Observations

Abstract
Here we describe Stylobates calcifer sp. nov. (Cnidaria, Actiniaria, Actiniidae), a new carcinoecium-forming sea anemone from the deep-sea floor of Japan. Stylobates produces a carcinoecium that thinly covers the snail shells inhabited by host hermit crabs Pagurodofleinia doederleini. The new species is distinct from other species by the shape of the marginal sphincter muscle, the distribution of cnidae, the direction of the oral disk, and host association. The species’ novelty is supported by the data of its mitochondrial genes 12S, 16S, and COIII and nuclear genes 18S and 28S. Also, we conducted behavioral observation of this new species, focusing on the feeding behavior and interaction with the specific host hermit crab. Our observations suggest that this sea anemone potentially feeds on the suspended particulate organic matter from the water column or the food residuals of hermit crabs. When the host’s shell changed, intensive manipulation for transference of S. calcifer sp. nov. was recorded. However, although the hermit crab detached and transferred the sea anemone to the new shell after shell change, the sea anemone did not exhibit active or cooperative participation. Our data suggest that the sea anemone may not produce a carcinoecium synchronously to its host’s growth, contrary to the anecdotal assumption about carcinoecium-forming sea anemones. Conversely, the host hermit crab’s growth may not depend entirely on the carcinoecium produced by the sea anemone. This study is perhaps the first observation of the behavioral interaction of the rarely studied carcinoecium-forming mutualism in the deep sea.

  Behavioral sequence of the hermit crab Pagurodofleinia doederleini transferring the sea anemone  Stylobates calcifer sp. nov. from the original snail Glossaulax reiniana shell to a new one.
(A) The hermit crab begins tapping the pedal disk and column of the sea anemone with its walking legs and chelipeds. (B) The hermit crab uses one or both of its chelipeds to pinch and remove S. calcifer sp. nov. from the G. reiniana shell. (C) Stylobates calcifer sp. nov. displays no shell-mounting action after being removed from the original shell. (D) The sea anemone is turned to the upside-down position (facing up the pedal disk) by the crab. (C) The hermit crab rides on the pedal disk of the sea anemone and fits the shell to the curved line of the pedal disk. (E) The sea anemone settles down in a new shell of the host hermit crab with a usual position.

Ecological note: Stylobates calcifer sp. nov. was exclusively found on the shells inhabited by Pagurodofleinia doederleini, consistent with previous studies (Uchida and Soyama, 2001; Yanagi, 2006; Yoshikawa et al., 2019). However, P. doederleini without S. calcifer sp. nov. was sometimes collected in this study. One individual was usually attached to one host hermit crab, consistent with previous studies (Uchida and Soyama, 2001; Yanagi, 2006; Yoshikawa et al., 2019).

Distribution and habitat: All of the samples were collected from the Sea of Kumano (Uchida and Soyama, 2001; Yoshikawa et al., 2019) and Suruga Bay. All of the previous records were from the Pacific Ocean facing the middle of Honshu Island to Kyushu (Uchida and Soyama, 2001; Yanagi, 2006). The specimens were distributed at 100–400 m from the fine sand and soft mud (Fig. 1; Table 1).


Etymology: The specific name “calcifer” is driven from the name of a resident fire-demon Calcifer, which appeared in Howl’s Moving Castle, a fantasy novel by British author Diana Wynne Jones, published in 1986; the story is the original version of the Japanese animated film of the same name, directed by Hayao Miyazaki (animated by Studio Ghibli). The shell-making ability of the new species in the species-specific relationship appears as if Calcifer was in a magical contract with the Wizard Howl, constructing his Moving Castle.

[Botany • 2022] Vaccinium paradoxum (Ericaceae: Vaccinieae) • An Unusual New Species from Sea Cliffs on Ultrabasic Forest of Luzon Island, Philippines


Vaccinium paradoxum M.N.Tamayo & P.W.Fritsch, 

in Tamayo & Fritsch, 2022.

Abstract
Vaccinium paradoxum is described as a new species of blueberry from the lowland ultrabasic forest of Northern Sierra Madre Natural Park, Luzon Island, Philippines. It resembles V. halconense, but differs by having shorter inflorescences, fewer flowers per inflorescence, a glabrous inner surface of the corolla, absence of anther spurs, and a glabrous style. Vaccinium paradoxum is unique among the currently known blueberries in Malesia by the presence of sessile glands borne on the pedicel and predominantly near the centre or scattered on the calyx lobes. It is also the only known Philippine Vaccinium to inhabit lowland ultrabasic forest on sea cliffs.

Vaccinium paradoxum M.N.Tamayo & P.W.Fritsch, sp. nov. 

Diagnosis: Vaccinium paradoxum resembles V. halconense Merr. by its leaf shape, leaf dimension, and flower color, but differs by having shorter inflorescences (1.3–3.5 cm vs. 5.0–7.0 cm), fewer flowers per inflorescence (5–8 vs. 10–15), glabrous inner surface of corolla (vs. pubescent), absence of anther spurs (vs. present), and a glabrous style (vs. pubescent). Moreover, the sessile glands borne on the pedicels and predominantly near the centre or scattered on the calyx lobes of V. paradoxum is a unique character among Vaccinium in Malesia (Fig. 2). 

Distribution and Habitat: The new species is currently known only from the type locality in the lowland ultrabasic forest of NSMNP at ca. 20 m asl on sea cliffs. 

Etymology: The epithet “paradoxum” is from the Latin meaning, in part, puzzling or unusual. This is in reference to the unique presence of sessile glands borne on the pedicel and predominantly near the centre of the calyx lobes of the new species.

[Botany • 2022] Ouratea yamamotoana (Ochnaceae) • A New Species from the Brazilian Atlantic Forest


Ouratea yamamotoana Fraga, G.H.Shimizu & D.B.O.S.Cardoso,

in Fraga, Shimizu & Cardoso, 2022.
 
ABSTRACT
The new species Ouratea yamamotoana (Ochnaceae) from the Brazilian Atlantic Forest biodiversity hotspot is described and illustrated. The new species resembles Ouratea camposportoi, from which it differs by the persistent stipules, chartaceous leaves with cordate or slightly auriculate base, flowers with smaller pedicels, spathulate or elliptic petals, longer gynophore, and fruit with a subterete to clavate carpophore. It is assessed as Vulnerable (VU) using IUCN Red List criteria and highlights the threats to the highly endemic plant diversity of the Atlantic Forest.

Keywords: Brazil, Malpighiales, morphology, taxonomy

Ouratea yamamotoana Fraga, G.H.Shimizu & D.B.O.S.Cardoso, sp. nov.

Similar to Ouratea camposportoi Sleumer but differs by its persistent stipules (vs caducous in O. camposportoi); chartaceous leaves with cordate or slightly auriculate base and slightly revolute (vs leaves rigid chartaceous or coriaceous, with obtuse, truncated or rounded base, and distinctly revolute); flowers with pedicel measuring 6–8 mm long but reaching 7–11 mm long when in fruit, the petals spathulate or elliptic, and gynophore 1.2–1.8 mm long (vs pedicel 9–15 mm long when in flower and 14–16 mm long when in fruit, the petals obovate, and gynophore 0.9–1 mm long); and fruit with a subterete to clavate carpophore of 7–16 × 1.8–4 mm (vs carpophore elongate, piriform, 12–14 × 3.3–6.5 mm). 

 Etymology. The name pays homage to Professor Kikyo Yamamoto, who has made important taxonomic contributions to neotropical Ochnaceae, and especially Ouratea. She carried out an in-depth study of morphological traits to untangle the complex taxonomy of this genus and studied the Ouratea parviflora (A.DC.) Baill. species complex in her graduate studies. Kikyo has also played an important role training and guiding generations of plant systematists at Unicamp in São Paulo, Brazil, for over 30 years.

Abstract
The Jerusalem cricket subfamily Stenopelmatinae is distributed from south-western Canada through the western half of the United States to as far south as Ecuador. Recently, the generic classification of this subfamily was updated to contain two genera, the western North American Ammopelmatus, and the Mexican, and central and northern South American Stenopelmatus. The taxonomy of the latter genus was also revised, with 5, 13 and 14 species being respectively validated, declared as nomen dubium and described as new. Despite this effort, the systematics of Stenopelmatus is still far from complete. Here, we generated sequences of the mitochondrial DNA barcoding locus and performed two distinct DNA sequence-based approaches to assess the species' limits among several populations of Stenopelmatus, with emphasis on populations from central and south-east Mexico. We reconstructed the phylogenetic relationships among representative species of the main clades within the genus using nuclear 3RAD data and carried out a molecular clock analysis to investigate its biogeographic history. The two DNA sequence-based approaches consistently recovered 34 putative species, several of which are apparently undescribed. Our estimates of phylogeny confirmed the recent generic update of Stenopelmatinae and revealed a marked phylogeographic structure within Stenopelmatus. Based on our results, we propose the existence of four species-groups within the genus (the faulkneri, talpa, Central America and piceiventris species-groups). The geographic distribution of these species-groups and our molecular clock estimates are congruent with the geological processes that took place in mountain ranges along central and southern Mexico, particularly since the Neogene. Our study emphasises the necessity to continue performing more taxonomic and phylogenetic studies on Stenopelmatus to clarify its actual species richness and evolutionary history in Mesoamerica.

Abstract
 A new species of Lepanthes from the department of Antioquia apparently restricted to the north-central Andes of Colombia is described and illustrated. The new species is similar to L. alcicornis; however, it can be easily distinguished by the transversally lobulate petals that resemble the ears of a rabbit, the reniform lip with suboblong basal lobes surrounding the column, and the absence of an appendix on the lip.

Abstract
A new genus, Diplopathes, in the family Schizopathidae, and three new species are described from the Southwest Pacific and Antarctic region based on morphological data. The new genus superficially resembles Telopathes in being branched and having simple, bilateral pinnules, but differs in having strictly alternately arranged pinnules, and in having small polyps 4 mm or less in transverse diameter. Mitochondrial DNA placed Diplopathes and Telopathes in separate clades within the Schizopathidae, thus supporting the significance of seemingly subtle anatomical differences. The new species are: D. antarctica, with sparse branching, pinnules of up to 7 cm long, and polypar spines up to 0.045 mm tall; D. multipinnata, with dense branching, pinnules up to 3 cm long, and polypar spines up to 0.1 mm tall; and D. tuatoruensis, with very sparse branching, pinnules up to 10 cm long, and polypar spines up to 0.1 mm. Interestingly, the three new species do not form a monophyletic clade based on mitochondrial DNA. We propose and discuss two hypotheses to explain the results of the phylogenetic reconstruction, including that molecular and physical change are uncoupled or that we have uncovered another example of morphological convergence in unrelated species.

Abstract
The Thalasseleotrididae is a small family of exclusively marine gobioids. They form a sister taxon to the Gobiidae and Oxudercidae and are distinguished from most species in these families by having six branchiostegal rays and a membrane linking the hyoid arch to the first ceratobranchial. Here we use micro-CT informed morphological data and molecular phylogenetics to describe a new genus and species of thalasseleotridid discovered on a tropical oceanic coral reef in the central Coral Sea. Tempestichthys bettyae gen. et sp. nov. is the first tropical thalasseleotridid and differs from other members of the Thalasseleotrididae by having a T-shaped palatine and a distinctive shape and colouration. The three previously described thalasseleotridid species are endemic to temperate coastal waters of southern Australia and New Zealand and are all translucent brown with dorsoventrally compressed heads. However, Tempestichthys bettyae is laterally compressed with a pointed snout and is translucent white with opaque white and crimson red markings and a largely crimson iris. We discuss the unique characters of this new genus, including its distribution, form, colouration and diminutive size, and highlight the potential of there being undescribed diversity in the Thalasseleotrididae.
