Chrysosporium guizhouense & Chrysosporium hubeiense: Two new species of Onygenal Fungi from China.

Fungi of the Order Onygenales are Ascomycete Fungi capable of breaking down keratin, the protein that forms skin, scales, hair and feathers in terrestrial vertebrates. These Fungi lack large, conspicuous fruiting bodies and are often overlooked, but play an important role in the decomposition of vertebrate remains and droppings, as well as in soil dwelling microbial communities, and are responsible for some Human illnesses, including Athelete's Foot and a range of infections which found in AIDS sufferers.

In a paper published in the journal Phytotaxa on 19 August 2016, Yan-Wei Zhang, Wan-Hao Chen, Gui-Ping Zeng, Yu-Rong Wang, Xiao Zou, Yan-Feng Han, Shu-Yi Qiu and Zong-Qi Liang of the College of Life Science at Guizhou University describe two new species of Onygenal Fungi isolated from soil samples in China, both being placed in the soil-dwelling genus Chrysosporium.

The first species is named Chrysosporium guizhouense, meaning 'from Guizhou', having been isolated from a soil sample collected from under a dried Snake skin in Kaiyang County in Guizhou Province, China. The fungus formed fluffy white colonies on agar, denser in the middle and more sparse around the edges.

The second new species is named Chrysosporium hubeiense, meaning 'from Hubei', having been isolated from soil collected from under a feather in Songzi City in Hubei Province. This Fungus formed white, powdery colonies on agar, with irregular outlines, and yellow on the underside.
