A new endophytic fungus, described herein as Cunninghamella saisamornae, was isolated from soil collected from Chiang Mai Province, Thailand. This species was distinguished from the previously described Cunninghamella species by the presence of a chlamydospore formation, the lack of a zygospore stage and a maximum growth temperature of 45°C. Multi-gene phylogenetic analysis of internal transcribed spacers (ITS) and large subunit (LSU) of the nuclear ribosomal DNA (rDNA), along with the translation elongation factor 1-alpha (tef-1) genes, support the finding that C. saisamornae is distinct from other species within the genus Cunninghamella. A full description, color photographs, illustrations and a phylogenetic tree showing the position of C. saisamornae are provided.

Abstract Absidia is ubiquitous and plays an important role in medicine and biotechnology. In the present study, nine new species were described from China in the genus Absidia, i.e. A. ampullacea, A. brunnea, A. chinensis, A. cinerea, A. digitata, A. oblongispora, A. sympodialis, A. varians, and A. virescens. Besides, two varieties A. cylindrospora var. nigra and A. spinosa var. biappendiculata were elevated to a specific rank as A. nigra comb. nov. and A. biappendiculata comb. nov., respectively. These new taxa were proposed based on a comprehensive investigation of morphological traits (such as shape and size of sporangia, sporangiospores and projections on columellae), physiological feature (maximum growth temperatures), and multi-locus sequences (including internal transcribed spacer, large subunit D1-D2 domains of nuclear ribosomal DNA, partial translation elongation factor 1 alpha gene and actin gene). All species mentioned above are illustrated, and an identification key to all the known species of Absidia in China is included.

During a survey of endophytic fungi in aquatic plants collected from Tibet, PR China, a novel species, Ramichloridium endophyticum, was isolated from Potamogeton pectinatus. This novel species differs from other species of the genus Ramichloridium by its finely verrucose, obovoid, ellipsoidal–obovoid and occasionally subglobose conidia. Phylogenetic analysis of the combined sequences of the internal transcribed spacers (ITS) and the translation elongation factor 1-alpha gene (tef1-α) confirmed that the isolated strain represents a member of the genus Ramichloridium. A full description, illustrations and a phylogenetic tree showing the position of R. endophyticum are provided.

Abstract A novel species of Morosphaeria, Morosphaeria muthupetensis, saprobic on intertidal mangrove wood of Rhizophora mucronata from Muthupet mangroves on Kaveri River Delta, Tamil Nadu along the East coast of India, is described in this paper. Morosphaeria muthupetensis is characterized by large sub-globose to lenticular ascomata; long cylindrical to clavate, short pedicellate asci; small, fusiform to ellipsoidal ascospores with acute ends when compared to other Morosphaeria species. A multigene phylogeny obtained from a combined nuclear large subunit, small subunit, internal transcribed spacers rDNA and translation elongation factor 1-alpha sequence analysis revealed that M. muthupetensis is phylogenetically distinct and nested in between Morosphaeria velatispora and Morosphaeria ramunculicola and all these species constitute a strongly supported monophyletic clade sister to the genus Helicascus. Detailed descriptions and illustrations of M. muthupetensis are presented and compared with other Morosphaeria species.

Agaricus is a saprophytic mushroom genus widely distributed throughout the world. In this study, a survey of the Agaricus species carried out around Chiang Mai University in northern Thailand from 2018 to 2019 yielded 12 collections. Morphological characteristics and phylogenic analyses based on the internal transcribed spacers (ITS) and a fragment of the large subunit (LSU) of the nuclear ribosomal DNA (rDNA), and a fragment of the translation elongation factor 1-alpha (tef1) genes were investigated. The results revealed that these collections belong to six species including Agaricus erectosquamosus, Agaricus pallidobrunneus, Agaricus subrufescens, and three new species. Agaricus thailandensis sp. nov. was found to belong to Agaricus sect. Minores, which is placed in Agaricus subg. Minores. Aagricus pseudoerectosquamosus sp. nov. was placed in Agaricus sect. Brunneopicti within Agaricus subg. Pseudochitonia. Furthermore, Agaricus lannaensis remains an incertae sedis in Agaricus subg. Pseudochitonia. Additionally, this study was proposed that A. pallidobrunneus was discovered in Thailand for the first time. Full descriptions, color photographs, illustrations, and phylogenetic trees are provided.

A new saprophytic fungus, Pleurotus sirindhorniae, is described based on collections from northern Thailand. This species is characterized by greyish yellow to olive brown pileus, ellipsoid to elongate basidiospores and clavate to mucronate cheilocystidia. It is distinguished from the previously described Pleuotus species by its distinct morphological characteristics. Molecular phylogenetic analyses of the large subunit (LSU) and internal transcribed spacers (ITS) of the nuclear ribosomal DNA (rDNA), the translation elongation factor 1-alpha (tef1) and the RNA polymerase II largest subunit (rpb1) genes also support P. sirindhorniae as a distinct new species within the genus Pleurotus. A full description, color photographs, illustrations and a phylogenetic tree to show the position of P. sirindhorniae are provided.

Three New Species

The taxonomy of Oculimacula, Rhynchosporium and Spermospora is re-evaluated, along with that of phylogenetically related genera. Isolates are identified using comparisons of DNA sequences of the internal transcribed spacer ribosomal RNA locus (ITS), partial translation elongation factor 1-alpha (tef1), actin (act), DNA-directed RNA polymerase II largest (rpb1) and second largest subunit (rpb2) genes, and the nuclear ribosomal large subunit (LSU), combined with their morphological characteristics. Oculimacula is restricted to two species, O. acuformis and O. yallundae, with O. aestiva placed in Cyphellophora, and O. anguioides accommodated in a new genus, Helgardiomyces. Rhynchosporium s. str. is restricted to species with 1-septate conidia and hooked apical beaks, while Rhynchobrunnera is introduced for species with 1–3-septate, straight conidia, lacking any apical beak. Rhynchosporium graminicola is proposed to replace the name R. commune applied to the barley scald pathogen based on nomenclatural priority. Spermospora is shown to be paraphyletic, representing Spermospora (type: S. subulata), with three new species, S. arrhenatheri, S. loliiphila and S. zeae, and Neospermospora gen. nov. (type: N. avenae). Ypsilina (type: Y. graminea), is shown to be monophyletic, but appears to be of minor importance on cereals. Finally, Vanderaaea gen. nov. (type: V. ammophilae), is introduced as a new coelomycetous fungus occurring on dead leaves of Ammophila arenaria.

A New Species

In this paper we describe a new species of cave fungus belonging to Sporocadaceae (Amphisphaeriales), collected from Gem Cave, Fumin County, Yunnan Province, China. Initial morphological observations confirmed that our fungal collection is a pestalotioid species. Phylogenetic analyses of combined internal transcribed spacer (ITS), β-tubulin (TUB) and translation elongation factor 1-alpha (TEF1α) gene sequence dataset confirmed that our fungus forms an independent branch within Neopestalotiopsis. Thus, we describe our fungus as a new species of Neopestalotiopsis based on both morphology and multigene phylogeny. This is the first-ever report of Neopestalotiopsis from a cave habitat. A full description, micrographs and a phylogenetic tree showing the placement of the new species are provided.
