Hydnoporia corrugata

A resupinate corticioid fungus on hazel (Corylus) wood, noted for its ability to glue contacting branches together.

Monomitic hyphal system, with generative hyphae thin- to moderately thick-walled, hyaline or with faint brownish intracellular pigment, difficult to observe, up to 3.5 µm wide, densely interwoven, septate with simple septa (clampless).

Hymenial setae very abundant, very dark brown, very thick-walled, with slightly more hyaline apices.

Basidia small, 10-15 µm long and 3-4 µm wide, without basal clamps, apparently 4-spored.

Spores not observed, according to literature cylindric-ellipsoidal, smooth, hyaline, thin-walled, measuring 4.5-6 x 1.8-2.3 µm.
