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

Notes

Note that the specimen from Doctors Hill had larger spores than indicated by the literature. It was identified by DNA sequencing carried out by Eric Janke of the Hampshire Fungus Recording Group in association with the British Mycological Society. I originally identified it as the closely related H. medioburiense.
