Habitat

Usually on rotten wood from deciduous trees and shrubs, less often on rotten wood from conifers

Spore Print

White

Microscopic Features

Spores subspherical, smooth (3-3.5) x (2-2.5) µm2. Basidia slenderly club shaped, four spored. Hyphal system monomitic, hyphae 2 to 3 µm wide, septate with clamps. Septocystidia cylindrical, about 5 µm wide, septate, clamps present.

Edibility

Unknown but of no value

Notes

Microscopically the specimen shown matches Ceraceomyces sublaevis. The specimen shown was DNA sequenced by Eric Janke of the Hampshire Fungus Recording Group in association with the BMS. The results show that it is gentically closely related to, but distinct from, Ceraceomyces sublaevis. The DNA sequence for the ITS region matches that of an undescribed specimen in the GENBANK database. Interestingly Eric sequenced two specimens from the Kew herbarium. One matched Ceraceomyces sublaevis, the other did not.
