Skeletocutis friata

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,[1] 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 (Alnus glutinosa).[2] 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.[3]

The external appearance of the fruit body is unremarkable, and similar to other soft, light-coloured pored crust fungi such as Hyphodontia radula, Ceriporiopsis balaenae, and young specimens of Ceriporiopsis resinascens. The microscopic characteristics of S. friata however, are quite distinct from others in Skeletocutis: "Generative hyphae dominate all parts of the basidiocarp as a delicate, uniform network, and skeletals intermingle as isolated, worm-like structures." The fungus is named (friata) for the friable (easily crumbled) texture the fruit bodies take on when dry.[3]
