Season

All year

Distribution

Rarely recorded, probably infrequent

Habitat

On rotten wood from deciduous trees

Microscopic Features

Spores cylindrical to narrowly ellipsoidal, smooth (8-14.5) x (3-5.5) µm2. Basidia 4 spored, clavate to suburniform. Hyphal system monomitic, hyphae 3 to 4 µm wide, clamped. Leptocystidia cylindrical, thin walled, smooth.

Edibility

Inedible

Notes

The spore sizes given here are significantly larger than is usually given in the literature. This is due to the second specimen having large spores. Its identity is certain as it was DNA tested by the Hampshire Fungus Recording Group and British Mycological Society and found to match known DNA sequences for this species. I originally identified the second specimen as H. medioburiense, a very closely related species.
