A New Species

A new species, Colletotrichum menglaense, isolated from air in Mengla, Xishuangbanna, Yunnan Province, China, was characterized and described combining morphological characteristics and multigene phylogenetic analysis. Morphologically, it is characterized by oblong, sometimes slightly constricted, micro-guttulate conidia and simple obovoid to ellipsoidal appressoria. Phylogenetic analysis of the ITS, ACT, CHS, and GAPDH sequences showed that C. menglaense belongs to the C. gloeosporioides complex. The pathogenicity of C. menglaense on fruits of several crop plants, including strawberry, orange, grape, tomato, and blueberry, was tested and confirmed by the re-isolation of C. menglaense.

A New Species

A new species of Polyporales, named as Skeletocutis yunnanensis, was collected on angiosperm wood in northern Yunnan Province, southwestern China. It is described based on morphological characteristics and molecular evidence. The species belongs to the Skeletocutis subincarnata complex, but differs morphologically from all known species of the genus by white, cream to buff pores surface, angular pores mostly 5–6 per mm with entire mouths, a dimitic hyphal structure both in trama and subiculum, generative hyphae in whole basidiocarps covered by fine crystals, skeletal hyphae unchanged in KOH, not agglutinated, allantoid basidiospores measured as 3.5–4.5 × 1.0–1.2 µm, and growth on angiosperm wood. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions indicated that the new species grouped with Skeletocutis and nested in the tyromyces clade.

A New Species

Meiogyne oligocarpa sp. nov. (Annonaceae) is described from Yunnan Province in Southwest China. It is easily distinguished from all previously described Meiogyne species by the possession of up to four carpels per flower, its bilobed, sparsely hairy stigma, biseriate ovules and cylindrical monocarps with a beaked apex. A phylogenetic analysis was conducted to confirm the placement of this new species within Meiogyne. Meiogyne oligocarpa represents the second species of Meiogyne in China: a key to the species of Meiogyne in China is provided to distinguish it from Meiogyne hainanensis. Paraffin sectioning was undertaken to study the anatomy of the corrugations on the inner petals of Meiogyne oligocarpa to verify whether they are glandular.

The genus Protubera includes gasteroid species. Its members are globally distributed in tropical, subtropical, and temperate areas, and presently, six species are recognized. In this paper, Protubera beijingensis from North China is described as a new species. Its morphological description and illustration are provided in detail and compared with morphologically similar species. A multigene phylogenetic analysis based on nLSU, atp6, and rpb2 sequences of the genus Protubera also identifies this organism as a new species within Protubera.

A new polypore, Ceriporia albomellea, collected from tropical China, is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by thin, resupinate basidiome with a white subiculum, cottony margin, white to cinnamon-buff pores, clavate cystidia and oblong-ellipsoid basidiospores measured as 3.1–3.8 × 1.7–2 µm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions supported C. albomellea as a distinctive species belonging to Ceriporia.

Paris lihengiana (Melanthiaceae), a new species from Yunnan Province, China, is described and illustrated based on evidence from morphological characters and molecular phylogeny. It differs from other species of Paris in its pubescent stem, pedicel and abaxial leaf surface, as well as other characters. Molecular phylogenetic analysis of 33 taxa in Paris was conducted based on nuclear ribosomal ITS and six plastid markers. Paris lihengiana is supported as a new species by both morphological characters and molecular data.

A New Species

Species in Lecanicillium are pathogens that parasitize various arthropods, nematodes, and other fungi. In an investigation of intestinal fungi associated with Marmota monax in China, three strains belonging to the genus Lecanicillium were isolated from the fresh fecal samples. Based on multi-locus phylogenetic analysis of the combined sequences (ITS, LSU, SSU, TEF, RPB1 and RPB2) and morphological characteristics, all species in Lecanicillium were well-separated. The three intestinal strains were assigned to a new species described as L. coprophilum in this paper. The new species differs morphologically from other Lecanicillium species by its dimensions of conidiogenous cells and conidia, the shape of conidia, dictyochlamydospores and swollen hyphae. The differences of L. coprophilum from other Lecanicillium species and closely related taxa are briefly discussed.

During a survey of rhizosphere soil fungi of Eucommia ulmoides in China, three Gongronella strains were isolated. Phylogenetic analysis showed that these strains grouped into a separate subclade, closely related to Gongronella sichuanensis. The new strains could be distinguished from G. sichuanensis by the smooth-walled, subglobose, or conical-cylindrical apophyses. Both phylogenetic analysis and morphological characteristics supported the three strains being a new species, named as Gongronella zunyiensis.

Sorbus dolichofoliolatus (Rosaceae) sp. nov. from Yunnan Province, China, is described and illustrated based on the collections deposited at the herbarium CDBI. The new species is similar to S. rehderiana in infructescence with sparsely rust-brown short hairs, fruit size, and glabrescent leaflets, but the former has longer and wider leaflets, persistent stipules and pinkish fruit color. A molecular phylogenetic analysis supports that the new species is distinguishable from related species in the genus.

Paris polyphylla is an important perennial medicinal plant in China. A disease similar to gray mold on P. polyphylla occurred at the seedling stage in March 2016 and 2017 in Tengchong city, Yunnan Province of China. The disease resulted in up to 50% mortality in serious cases. Isolates from diseased plants grew 10.6 mm/day at 20°C on PDA. After 21 days, sclerotia were spherical to elliptical (0.4–2.5 × 0.3–1.8 mm). Conidia from diseased tissues were hyaline to pale brown, long, ovoid, unicellular, and measured 15.1–24.5 × 8.8–13.4 μm; conidiophores were 526–1,064 ×12–15 μm. Isolates did not form conidiophores or conidia on PDA or MYA. A phylogenetic analysis based on G3PDH, RPB2, and HSP60 sequence data supported assignment of three representative isolates as a new species of Botrytis. Based on morphological, phylogenetic characteristics and Koch’s Postulates, the causal agent of gray mold on P. polyphylla was identified as a novel species, Botrytis polyphyllae.

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.
