features
Macroscopic features
Hyphoderma orphanellum has resupinate, membranous-waxy fruiting bodies typical of the genus Hyphoderma . They are whitish to white-gray. 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 Hyphoderma orphanellum is monomitic, i.e. it only has generative hyphae . The 2–3 µm wide hyphae are hyaline and encrusted, the septa have buckles . The cystids are cylindrical and thickened at the base. They end in a club-shaped tip, which is often covered with hyaline droplets, and with a size of 50–80 × 8–10 µm clearly protrude from the fruit layer. The basidia of the species are initially club-shaped to approximately urn-shaped and constricted in the middle, have four (rarely only two) Sterigmata and measure 20–30 × 6–8 µm. They have buckles at the base. Their spores are egg-shaped to ellipsoid, hyaline and thin-walled. They measure 8–10 × 5–6 µm and always have an extension ( apiculus ).
distribution
The known distribution of the species covers large parts of northern, southern, western and eastern Europe to the Caucasus , but is considered very rare everywhere.
ecology
Hyphoderma orphanellum grows on rotten, mostly debarked and fallen dead wood from deciduous trees . Due to the rarity of the species, no preferences for substrates can be given; it was found on alders ( Alnus spp.) And willows ( Salix spp.), Among others .
