Record Summary resupinate covering base of Oak stump
Associated organism: on dead stump of Quercus
Identification Notes: Abundant resupinate growth, growing completely round the stump and overgrowing mosses etc., but without pilei or pores; found after a very dry spell.
Margin: velvety, in places weakly fringed with tiny rhizomorphs, concolourous.
When kept in a box for a few days it developed tiny white marginal rhizomorphs.
Setae absent. Hymenium absent.
KOH: purple.
Hyphae: with rusty orange encrustation which dissolves completely in 10% ammonia.

A further collection from the same stump (Aug 03) dropped spores, but these were apparently from a contaminant or parasite:
Spore print: almost white, non-amyloid.
Spores: ovoid, 13-18/10.25-15µm, with large apiculus.
Hyphae probably not clamped.
