Phaeosphaeria chinensis sp. nov. was found on dead leaves, collected from Guangdong Province, China. Morphology of the new species was compared with other Phaeosphaeria species and related genera of Phaeosphaeriaceae. Phylogenetic analyses of combined ITS, LSU, SSU and TEF-1 sequence data based on maximum parsimony (MP), maximum likelihood (ML) and Bayesian inference (BI) revealed that P. chinensis as a distinct species within the Phaeosphaeria with high bootstrap support. The comparison of the new species with other Phaeosphaeria species and a comprehensive description and micrographs are provided. The linkage of sexual and asexual morphs of the new species is also showed.

A New Species

A new species of the genus Gonyosoma Wagler is described from Yunnan Province, China. The new species closely resembles G. prasinum (Blyth), but it is differentiated from the latter species by the following characters: precloacal plate divided, iris blue and inside of mouth greyish-white in life. Based on phylogenetic analyses of mitochondrial cytochrome b sequence data, the new species is recovered as the sister species to G. prasinum by Bayesian Inference and Maximum Likelihood analyses. The uncorrected pairwise distance between the new species and other species of the genus Gonyosoma ranged from 11.78% to 17.07% calculated using the mitochondrial cytochrome b sequence. This discovery increases the number of Gonyosoma species to seven.

This study embodies description of a novel Monochaetia species, from dead leaf of a Quercus sp. collected from Lijiang in Yunnan Province, China. Morphologically, it conforms to the characters of Monochaetia by presence of single apical and basal appendage on the conidia. The new species forms a sister clade to M. ilexae in the combined LSU-ITS and TUB2 sequence data based phylogenetic analyses and remain distinct from the latter species in having larger conidia, long apical appendage, long basal appendage and long conidiogenous cells. Therefore, we introduce Monochaetia sinensis as a novel taxon with a comprehensive description and illustration.

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

Amanita rufobrunnescens is described as a new species in the subgenus Lepidella section Amidella from Guangdong Province, China. It is characterized by whitish basidiomes that bruise reddish brown, brownish sub-membranous to fibrillose volval remnants on the pileus, a striate pileus margin, white lamellae with truncate lamellulae, grayish orange to light brown volva, amyloid basidiospores that are ellipsoid to elongate (9.5–)10–12(–13) × (5–)5.5–6.5(–7) µm, and 5–10 μm wide pileipellis hyphae with yellowish vacuolar pigments. There are no clamp connections. Molecular phylogenetic analyses based on the nuclear ribosomal large subunit of nuclear ribosomal DNA (LSU) and internal transcribed spacer (ITS) sequences reveal that A. rufobrunnescens is a distinct species.

A novel ascomycete genus, Longihyalospora, occurring on leaf litter of Ficus ampelas in Dahu Forest Area in Chiayi, Taiwan is described and illustrated. Longihyalospora is characterized by dark mycelium covering the upper leaf surface, elongate mycelial pellicle with ring of setae, pale brown to brown peridium, broadly obovoid, short pedicellate asci and hyaline, fusiform, elongated (tapering ends) and multi-septate ascospores with a thin mucilaginous sheath. Phylogenetic analyses of combined ITS, LSU and SSU sequence data revealed Longihyalospora as a distinct genus within the Chaetothyriaceae with high bootstrap support. Moreover, based on morphological similarities, Chaetothyrium vermisporum transferred to the new genus. In addition, Ceramothyrium longivolcaniforme is reported for the first time on Ficus ampelas. Newly added species are compared with other similar species and comprehensive descriptions and micrographs are provided.

A New Species

Bamboo is a widespread plant with medicinal value. During our taxonomic study on medicinal plants, three collections of Distoseptispora were made from China and Thailand. Phylogenetic analyses of combined LSU, ITS and RPB2 sequence data showed that two collections represented a new species, phylogenetically distinct from other described species in Distoseptispora. This new species has macronematous, mononematous conidiophores, polyblastic or monoblastic conidiogenous cells and acrogenous, solitary, straight, obclavate, multi-septate, thick-walled conidia. Distoseptispora bambusae sp. nov. is introduced with illustrations and a comprehensive description. The third collection on dead wood from Thailand was identified as D. tectona with newly-generated molecular data for this taxon.

Collections of microfungi on Pandanus species (Pandanaceae) in Krabi, Thailand resulted in the discovery of a new species in the genus Parasarcopodium, producing both its sexual and asexual morphs. In this paper, we introduce P. pandanicola sp. nov., with an illustrated account. Evidence for the new species is provided by distinct morphology and phylogenetic analyses. This is also the first report of the sexual morph of Parasarcopodium. The phylogenetic trees used Maximum Likelihood and Bayesian analyses of combined LSU, SSU, TEF1 and RPB2 sequence data to show the placement of the new species in Stachybotryaceae.

A new species of Neolinocarpon, N. phayaoense was found on a branch of Hevea brasiliensis in northern Thailand. The new species is introduced in this paper, with evidence from morphology and phylogenetic analyses. Descriptions, illustrations and notes are provided for the new taxon. Maximum-likelihood and Bayesian inference analyses of a combined LSU and ITS sequence data clarified the phylogenetic affinity in Neolinocarpon, with the species separated from Linocarpon in Linocarpaceae. Neolinocarpon is morphologically distinct from Linocarpon in having immersed ascomata.

Two new Platanthera (Orchidinae, Orchideae, Orchidoideae) species, P. guangdongensis and P. zijinensis, from the Guangdong Province in China are described and illustrated based on morphological and molecular analyses. Platanthera guangdongensis is leafless and resembles P. fujianensis, but it differs in terms of the shorter and/or smaller inflorescence, floral bract, dorsal sepal, lateral sepal, petal, and ligulate lip. Platanthera zijinensis is morphologically similar to P. minor, but it differs by the ovate-oblong to ovate floral bract, colour of flower, ovate dorsal sepal, oblong lateral sepal, ovate-oblong lip, and curved forward spur. The phylogenetic analyses based on nuclear ribosomal ITS and chloroplast (rbcL and matK) sequence data support that P. zijinensis and P. guangdongensis being sisters to each other and genetically sister to P. minor. The chloroplast rbcL of P. guangdongensis is a pseudogene, supporting its characterization as a holomycotrophic orchid.

Lentithecium cangshanense sp. nov. (Lentitheciaceae, Dothideomycetes), was found on submerged decaying wood in a freshwater stream in Yunnan Province, China. The species is characterized by its black, semi-immersed to superficial, globose ascomata, cylindrical or obclavate, short pedicellate, bitunicate asci and bi-seriate, fusiform, 1-septate, yellowish to brown ascospores. Phylogenetic analyses of combined LSU, SSU and RPB2 sequence data show that L. cangshanense belongs in the family Lentitheciaceae, order Pleosporales and is a distinct species in the genus. The new species is introduced with an illustrated account and compared with morphologically and phylogenetically similar species.
