features
Macroscopic features
Hyphoderma capitatum has resupinate, membranous-waxy fruiting bodies typical of the genus Hyphoderma . They are whitish to white-gray, often yellowish when dried. Your hymenium is smooth, but under a magnifying glass you can see pores and protruding cystids . Their edge is fibrous and contourless.
Microscopic features
The hyphae structure of Lagarobsidium capitatum is monomitic, so it only shows generative hyphae . The 2–3 µm wide hyphae are hyaline and heavily branched; the septa do not have a buckle . The cystids are pointed and thickened at the base. They end in a blunt point and protrude clearly from the fruit layer with 50–125 × 4–12 µm. The basidia of the species are initially club-shaped, later approximately urn-shaped, have four (rarely only two) Sterigmata and measure 25–30 × 5–6 µm. They have no buckles at the base. Their spores are approximately spherical, hyaline and thick-walled. They measure 8–11 × 7–9 µm and always have an extension.
distribution
The known distribution of the species includes Europe as well as Japan .
ecology
Hyphoderma capitatum grows on rotten, mostly debarked and fallen dead wood of conifers . Typical substrates are Norway spruce ( Picea abies ) or black pine ( Pinus sylvestris ). It colonizes moist habitats indicated by Sphagnum as well as Hylocomium - Vaccinium societies.
