During an investigation into the microfungi on Dracaena fragrans in Thailand, a saprobic taxon belonging to Glomerellaceae was collected. Based on morphological characterization and combined phylogenetic analyses of ITS, GAPDH, CHS-1, ACT and TUB2 sequence data from the sexual and asexual morphs our taxon was identified as a new species of Colletotrichum. Colletotrichum dracaenigenum sp. nov. is introduced here with a full description, colour photographs of morphological characteristics and a phylogenetic tree to show the placement of the new taxon in the gloeosporioides species complex.

A New Species

The Epicopeiidae is a small geometroid family distributed in the East Palaearctic and Oriental regions. It exhibits high morphological diversity in body size and wing shape, while their wing patterns involve in various complex mimicry rings. In the present study, we attempted to describe a new genus, and a new species from Vietnam, with comments on two assumed congeneric novel species from China and India. To address its phylogenetic affinity, we reconstructed the phylogeny of the family by using sequence data of COI, EF-1α, and 28S gene regions obtained from seven genera of Epicopeiidae with Pseudobiston pinratanai as the outgroup. We also compared the morphology of the new taxon to other epicopeiid genera to affirm its taxonomic status. The results suggest that the undescribed taxon deserve a new genus, namely Mimaporia gen. n. The species from Vietnam, Mimaporia hmong sp. n., is described as new to science. Under different tree building strategies, the new genus is the sister group of either Chatamla Moore, 1881 or Parabraxas Leech, 1897. The morphological evidence, which was not included in phylogenetic analyses, however, suggests its potential affinity with Burmeia Minet, 2003. This study also provides the first, although preliminary, molecular phylogeny of the family on which the revised systematics and interpretation of character evolution can be based.

In this paper, we report a new asexual-morph taxon belonging to the family Cordycipitaceae (Hypocreales), which is associated with a sexual morph of an ophioceras-like taxon on submerged wood collected from Baoshan, Yunnan, China. Morphologically, this new taxon is similar to known asexual morphs of Lecanicillium and characterized by conidiophores arising from hyaline hyphae, with gregarious, ellipsoid to ovoid, aseptate conidia. Phylogenetic analyses of a combined LSU, SSU, tef1-α and ITS sequence dataset positions our taxon in Cordycipitaceae and close to Lecanicillium sp. (CBS 639.85) and L. primulinum. Lecanicillium subprimulinum is introduced as a new species with support from molecular data.

Iochroma amicorum M. Cueva, S. D. Sm. & S. Leiva (Solanaceae), a new species from cloud forests of Central Peru, is described and illustrated. Phylogenetic analyses of DNA sequence data suggest that Iochroma amicorum is closely related to I. nitidum, I. umbellatum, I. grandiflorum and I. tingoanum, which collectively form the “U” clade of Iochrominae. Certain morphological characteristics of calyx and corolla as well as the type of habitat appear to be common in species of this clade. Iochroma amicorum is easily distinguished from other members of the “U” clade by its campanulate or funnel-shaped corolla with short and slightly reflexed lobes, the presence of an expanded stapet at the point of filament insertion with short lateral extensions united to the corolla, and its globose usually white fruits with tinges of purple at the base. Distribution, phenology and are discussed together with the position of the new species in Iochrominae. Iochroma amicorum is assessed as Endangered according to IUCN criteria B1ab (i, iii)

A New Species

Colletotrichum has numerous host range and distribution. Its species are important plant pathogens, endophytes and saprobes. Colletotrichum can cause regular or irregular depressions and necrotic lesions in the epidermal tissues of plants. During this research Colletotrichum specimens were collected from Mengyin County, Shandong Province, China. A multi-locus phylogenetic analysis of ITS, GAPDH, CHS-1, ACT, TUB2, CAL and GS sequence data combined with morphology, revealed a new species and two known species, viz. C. mengyinense sp. nov., C. gloeosporioides and C. pandanicola, belonging to the C. gloeosporioides species complex. The new species is described and illustrated in this paper and compared with taxa in the C. gloeosporioides species complex.

A new species, Calocybe decurrens, is illustrated and described in detail based on morphological characteristics and phylogenetic analyses. Calocybe decurrens is mainly characterized by its decurrent gills and by its stipe that discolors upon maturation. Molecular phylogenetic analyses were based on the internal transcribed spacer (ITS1-5.8S-ITS2) and the large subunit of the nuclear ribosomal DNA (nrLSU) sequences. The results indicated that its affiliation is in genus Calocybe, where it occupies an isolated position. A full description, color images, illustrations and a phylogenetic tree to show the placement of the new species are provided.

The genus Trichoglossum (Geoglossaceae) is characterized by black, clavate, stipitate apothecia with hymenial setae. We collected T. cf. octopartitum from China and a new species of Trichoglossum from Thailand, the latter named as T. septatum. According to morphological examination and molecular phylogenetic analyses of ITS sequence data, T. septatum diverges from other Trichoglossum species. Full descriptions, colour figures, and a phylogenetic tree to show the positions of T. cf. octopartitum and T. septatum are provided, and the two species are compared with allied taxa. The important morphological characteristics of Trichoglossum species are also summarized.

A New Species

A new Seifertia species was isolated from hanging rachides of Rhododendron decorum in Yunnan Province, Southwest China. The new taxon was compared with the type species, S. azalea and differs in having wider conidiophores, with hyaline to subhyaline and smaller conidia, while S. azalea has olive-brown to brown, rarely branched conidiophores, and pale brown or olive-brown, very rarely septate conidia. Phylogenetic analyses of combined LSU, SSU and TEF1-α sequence data show that S. shangrilaensis forms a robust clade with S. azalea nested among the species of Melanommataceae in the order Pleosporales. A new species, S. shangrilaensis is introduced in this study, and Seifertia should be placed in Melanommataceae (Pleosporales, Dothideomycetes) based on phylogenetic analysis. Description and illustration of Seifertia shangrilaensis are provided with notes and its introduction is supported by molecular data.

Diverse Range

Palms (Arecaceae) are substrates for a highly diverse range of fungi. Many species are known as saprobes and many are important plant pathogens. Over the course of our studies of micro-fungi from palms in Thailand, two new taxa were discovered. Morphological characteristics and phylogenetic analyses of combined ITS, LSU, SSU, and tef1-α sequence data revealed their taxonomic positions within Massarinaceae. There are currently ten genera identified and accepted in Massarinaceae, with the addition of the two new genera of Haplohelminthosporium and Helminthosporiella, that are introduced in this paper. Each new genus is provided with a full description and notes, and each new taxon is provided with an illustration for the holotype. A list of identified and accepted species of Helminthosporium with morphology, host information, locality, sequence data, and related references of Helminthosporium reported worldwide is provided based on records in Species Fungorum 2021. This work provides a micro-fungi database of Haplohelminthosporium, Helminthosporiella, and Helminthosporium which can be modified and validated as new data come to light.

Species of Psilocybe collected in Yunnan Province in southwest China were identified using both morphological characteristics and phylogenetic analyses of ITS and nrLSU sequence data. Six phylogenetic species were recognized among the studied collections. In this paper, Psilocybe ruliensis is introduced as a new species, while Psilocybe keralensis is new to China, P. aff. fasciata is new to Yunnan and P. chuxiongensis is recollected in Yunnan Province. The remaining two phylogenetic species are not described or detailed due to the paucity of the material. The four species appear to be endemic to Asia.
