Skeletocutis yunnanensis is a species of poroid crust fungus in the family Polyporaceae that was described as a new species in 2016. The type specimen was collected in northern Yunnan Province, southwestern China, where it was found growing on decaying angiosperm wood in a temperate forest. [1]

Description

The fungus is characterized by a white, resupinate (crust-like) fruit body with a cream to buff pore surface, and the near absence of a sterile margin when mature. The angular pores number 5–6 per mm with entire mouths. It has a dimitic hyphal structure, containing both generative and skeletal hyphae. The generative hyphae in the subiculum and the trama are covered by fine crystals. The spores are allantoid (sausage-shaped), hyaline, smooth and thin walled, measuring 3.5–4.5 by 1.0–1.2  µm. They typically contain two small oil droplets. [1]

<i>Skeletocutis</i> genus of fungi

Skeletocutis is a genus of about 40 species of poroid fungi in the family Polyporaceae. The genus has a cosmopolitan distribution, although most species are found in the Northern Hemisphere. Skeletocutis causes a white rot in a diverse array of woody substrates. Their fruit bodies grow as a crust on the surface of the decaying wood. Sometimes the edges of the crust are turned outward to form rudimentary bracket-like caps.

Skeletocutis africana is a species of poroid crust fungus in the family Polyporaceae. Described as new to science in 2006 by mycologists Leif Ryvarden and Peter Roberts, the fungus is found in Cameroon, where it grows on logs in tropical lowland rainforest environments. The type collection was made in Korup National Park, in South West Province.

Skeletocutis bambusicola is a species of poroid crust fungus in the family Polyporaceae. It was described as new to science in 2012 by mycologists Li-Wei Zhou and Wen-Min Qin. It is found in southern China, where it grows on dead bamboo. The type collection was made in Mengla County, Yunnan Province. The specific epithet bambusicola refers to its growth on bamboo. At the time of publication, S. bambusicola was the 22nd Skeletocutis species recorded from China.

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.

Skeletocutis diluta is a species of poroid crust fungus in the family Polyporaceae. It was first described by Mario Rajchenberg in 1983 as a variety of Skeletocutis nivea. Rajchenberg and Alex David promoted the taxon to independent species status in 1992. The type specimen was collected in Puerto Esperanza, Misiones (Argentina), where it was found growing on Pinus taeda logs in a subtropical forest. It has since been found in Gabon. Skeletocutis diluta has effused-reflexed fruit bodies, meaning they are crust-like with a margin that is extended and bent backwards. It has small allantoid (sausage-shaped) spores measuring 3.1–3.5 by 0.5–0.8 μm. It features a dimitic hyphal system, but the skeletal hyphae dissolve in solution of potassium hydroxide.

Skeletocutis subvulgaris is a species of poroid, white rot fungus in the family Polyporaceae. Found in China, it was described as a new species in 1998 by mycologist Yu-Chen Dai. It was named for its resemblance to Skeletocutis vulgaris. The type collection was made in Hongqi District, Jilin Province, where it was found growing on the rotting wood of Korean pine.

Datroniella tropica is a species of crust fungus in the family Polyporaceae. Found in southwestern China, it was described as a new species in 2014 by mycologists Bao-Kai Cui, Hai J. Lee, and Yu-Cheng Dai, who placed it in the new genus Datroniella. The type collection was made in Tongbiguan Nature Reserve, where the fungus was found growing on a fallen angiosperm branch. The specific epithet tropica refers to its distribution in tropical China.

Skeletocutis nothofagi is a rare species of poroid crust fungus in the family Polyporaceae that is found in South America. It has been proposed for inclusion in the IUCN Red List of Threatened Species due to its highly restricted distribution and rare occurrence.

Skeletocutis friata is a rare species of poroid crust fungus in the family Polyporaceae. Found in Finland, it was first described as a new species in 1998 by Tuomo Niemelä and Reima Saarenoksa, with the name Skeletocutis friabilis. It was given the epithet friata three years later, after it was discovered that a tropical Asian species had already been given the name Skeletocutis friabilis, with a publication date two months prior to theirs. The holotype was collected by Saarenoksa in Sipoo, southern Finland, where it was found growing on the bark and exposed wood of a fallen twig of common alder. The authors later noted that subsequent searching of the type locality, as well as other locations in southern Finland, failed to turn up additional examples of this species.
