Skeletocutis yunnanensis

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.

Description

The fungus is characterized by a white, resupinate 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, hyaline, smooth and thin walled, measuring 3.5–4.5 by 1.0–1.2 μm. They typically contain two small oil droplets.
