Description
The fruit bodies of this fungus are crust-like with a waxy texture. Its dimensions are usually small, with a thickness of up to 2 mm, and a length typically no more than 2–3 cm (0.8–1.2 in). The pore surface is cream-white when fresh, but dries to a pale yellow or pale orange colour. The pores are tiny and angular, usually numbering 6–8 per mm.
The fungus has a dimitic hyphal system, meaning that it contains both generative and skeletal hyphae. Typical of the genus Skeletocutis, the generative hyphae of S. brevispora are encrusted with spiny crystals on the dissepiments (the tissue between the pores). Spores are cylindrical to somewhat sausage-shaped (allantoid), and measure 3–4 by 1–1.5 μm.
Habitat and distribution
Skeletocutis brevispora has only been recorded from Fennoscandia where it grows on dead fruit bodies of the polypore fungus Phellinus ferrugineofuscus. Rarely, it is found growing on dead spruce wood that has been rotted by this fungus.
