Taxonomy

It was first described in 1977 as a member of the now-defunct genus Incrustoporia by Derek Reid.[2] Walter Jülich transferred it to Skeletocutis in 1982.[3]

Description

The hyphal system is monomitic, meaning it contains only generative hyphae. These hyphae have clamps and are hyaline, thin-walled, richly branched, measuring 2–3 µm in diameter. Those close to the substrate are heavily encrusted. Cystidia are absent from the hymenium. Fusoid cystidioles present in the hymenium, thin-walled, not encrusted, 9–12 by 3–4 µm, with a basal clamp. The basidia are ovoid to clavate, four-sterigmate, 9–12 by 4–5 µm, with a basal clamp. Spores are oblong-ellipsoid, slightly curved, hyaline, smooth, do not stain with Melzer's reagent, and measure 3–4 by 1.5–2 µm.[4]

Habitat and distribution

Skeletocutis azorica is found only in the Azores of Portugal, where it causes a white rot on woody substrates of Pinus, Cryptomeria, and also on the fern Pteridium.[4]
