Postia cylindrica is a species of poroid fungus in the family Fomitopsidaceae. Found in Southern China, it was described as a new species in 2017 by Hai-Sheng Yuan. The type collection was found growing on a dead pine tree in Jiangxi. The fungus is characterized macroscopically by crust-like to effused-reflexed fruit bodies with a cream to buff coloured cap surface and a reddish-brown margin that curves inward. There are gloeoplerous (oily) hyphal cells in the cuticular layer, and an absence of cystidia in the hymenium. The fungus produces smooth, cylindrical, thin-walled spores measuring 4.7–5.2 by 1.3–1.5  µm. [1]

Polypore group of fungi

Polypores are a group of fungi that form fruiting bodies with pores or tubes on the underside. They are a morphological group of basidiomycetes like gilled mushrooms and hydnoid fungi, and not all polypores are closely related to each other. Polypores are also called bracket fungi, and their woody fruiting bodies are called conks.

Fomitopsidaceae family of fungi

The Fomitopsidaceae are a family of fungi in the order Polyporales. Most species are parasitic on woody plants, and tend to cause brown rots. The name comes from Fomitopsis + -aceae.

A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species which have been described previously or are related. The species description often contains photographs or other illustrations of the type material and states in which museums it has been deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct.

Fibroporia is a genus of ten species of poroid crust fungi in the family Fomitopsidaceae. The genus contains species similar to those in genus Antrodia, but they are phylogenetically distinct.

Fibroporia albicans is a species of poroid crust fungus in the family Fomitopsidaceae. It causes a brown rot. The fungus was described in 2015 as a species new to science, based on collections made in Jiangxi and Xizang Provinces, China. It is one of five Fibroporia species recorded in China.

Dacryobolus gracilis is a species of crust fungus in the family Fomitopsidaceae. This brown rot fungus was described as new to science in 2016 by Hai-Sheng Yuan. It has a fragile, waxy fruit body with small, slender spines. The fungus has been found in Chongqing and Guangxi, in southwestern China.

Mycorrhaphium sessile is a species of tooth fungus in the family Steccherinaceae that is found in China. It was described as a new species in 2009 by mycologists Hai-Sheng Yuan and Yu-Cheng Dai. The type collection was made in Yunnan, where it was found fruiting on a fallen branch.

Mycoleptodonoides tropicalis is a species of tooth fungus in the family Meruliaceae. It was described as new to science in 2013 by mycologists Hai-Sheng Yuan and Yu-Cheng Dai. The type collection was made in the Xishuangbanna Tropical Botanical Garden in Mengla County, where the fungus was found fruiting on a decaying angiosperm trunk. The specific epithet tropicalis refers to the tropical forest habitat.

Cerarioporia is a fungal genus in the family Polyporaceae. It is a monotypic genus, containing the single species Cerarioporia cystidiata, a wood-decaying poroid crust fungus found in tropical China. Cerarioporia resembles fungi placed in the genus Antrodia, but can be distinguished by its waxy to resinous fruit bodies, and microscopically by the thick-walled, encrusted cystidia. Additionally, Cerarioporia causes a white rot, while Antrodia are brown-rot fungi.

Ceriporia albomellea is a species of crust fungus in the family Irpicaceae. Found in China, it was described as new to science in 2017 by mycologists Yuan Yuan, Xiao-Hong Ji, Fang Wu, and Jia-Jia Chen. The fungus is characterized by its thin crust-like fruit body with a cottony white margin, and white to cinnamon-buff pores; it is this latter feature for which the fungus is named. Its spores are oblong to ellipsoid and measure 3.1–3.8 by 1.7–2 μm. The type locality is southern China's Hainan Island, a location rich with wood-inhabiting fungi.

Postia duplicata is a species of poroid fungus in the family Fomitopsidaceae that was described as a new species in 2014. It is found in Yunnan and Zhejiang provinces of China, where it causes a brown rot on angiosperm wood. The fungus is named (duplicata) for its characteristic two-layered context, a feature that distinguishes it from other Postia species. The spores made by this fungus are cylindrical, hyaline, smooth, and typically measure 3.8–5.8 by 1.8–2.5 µm.

Steccherinum subglobosum is a hydnoid fungus of the family Steccherinaceae. Found in China, it was described as new to science by mycologists Hai-Sheng Yuan and Yu-Cheng Dai in 2005. The type collection was found growing on a fallen angiosperm branch in Shennongjia Nature Reserve. The specific epithet subglobobum refers to the somewhat rounded shape of its spores.

Steccherinum subulatum is a hydnoid fungus of the family Steccherinaceae. Found in China, it was described as new to science by mycologists Hai-Sheng Yuan and Yu-Cheng Dai in 2005. The type collection was found growing on a fallen Celtis branch in Shennongjia Nature Reserve. The specific epithet subulatum refers to the shape of its skeletocystidia.

Dentocorticium hyphopaxillosum is a species of crust fungus in the family Polyporaceae. It is found in the Guangxi Autonomous Region of southern China, where it grows on fallen angiosperm branches. It was first described in 2014 as Dendrodontia hyphopaxillosa by mycologists Meng-Jie Li and Hai-Sheng Yuan, who thought it was related to other species of Dendrodontia based on morphological characteristics. It was transferred to the genus Dentocorticium in 2018 based on phylogenetic analysis; Dendrodontia was synonymized with Dentocorticium. Characteristics of D. hyphopaxillosum include its crust-like fruit bodies, cylindrical hyphal pegs, contorted dendrohyphidia that are frequently branched, and spores with an ellipsoid to somewhat cylindrical shape.
