features
Macroscopic features
The clay-colored bark fungus has resupinate, membranous-waxy fruiting bodies typical of the genus Hyphoderma . They are whitish to light gray, often with an ocher tint, and have no rhizomorphs . Your hymenium is smooth, but under a magnifying glass you can see pores and protruding cystids .
Microscopic features
As with all types of hyphoderma , the hyphae structure of the clay-colored bark fungus is monomitic , i.e. it only has generative hyphae . The 2–3 µm wide hyphae are hyaline and strongly branched, the septa have buckles. The cystids are tubular and thickened at the base. They end in a blunt point and protrude clearly from the fruit layer at 100–150 × 10–20 µm . The basidia of the species are club-shaped to approximately urn-shaped, have four sterigmata and measure 25–30 × 5–6 µm. They have a buckle at the base . Their spores are ellipsoidal to almost spherical, hyaline and thin-walled. They measure 6–10 × 4–5 µm and always have an extension ( apiculus ).
distribution
The known distribution of the species includes the whole of the Holarctic , Africa and with Argentina and Venezuela also South America.
ecology
The clay-colored bark mushroom grows on rotten, mostly debarked and fallen dead wood from conifers and deciduous trees . Typical substrates are Norway spruce ( Picea abies ) or poplars ( Populus spp.). It prefers shady and moist habitats, often indicated by the growth of ferns .
