Dimensions: Cap 2-8cm dia; stem 1-3cm tall x 0.3-1.0cm dia.
Fruit Body: Cap grey with brown or yellow tinges, darkening towards the centre, with whitish margin, shallowly infundibuliform, rosette-shaped, radially wrinkled and downy, margin smooth; stem concolorous or darker, equal, fibrillose but glabrous, typically several fused together; flesh: reddish-brown, darker in the stem; tough and corky; spines at first whitish or pallid then brown, more or less decurrent.
Spores: Hyaline, spiny, sub-spherical, non- amyloid, 3.5-4.5 x 3-4 µm . Basidia 4 spored; cystidia absent.
Odour: Fresh, not distinctive; dry, spicy.
Taste: Slightly Bitter.
Chemical Tests: None.
Occurrence: Late Summer to Autumn.

 

Qualifying criterion: 4.4: uncommon species associated with microhabitat
Justification: current BAP action for stipitate hydnoid fungi needs to be continued
Threats: habitat destruction of banks, paths and tracksides, vehicle compaction, mountain biking, felling of host trees especially sweet chestnut, eutrophication
Action Required: Survey and monitoring; protection against habitat loss and degradation; site liaison and management.
