Description: Hymenophore resupinate, annual, ceraceous, loosely attached by a central base, forming
orbicular or elliptical areas 3-5 x 2-3 cm; hymenial surface pallid flesh colour, drying orange
or reddishbrown with plum or purple coloured central regions, radiately ridged, folds either
regular and receding from the centre, or in a series of radiately arranged rounded tubercules
larger and more abundant towards the centre, peripherally plane or slightly rugulose, not
creviced; margin thinning out, fibrillose, to 2 mm broad, yellow or orange, drying wood
colour. Context white, to 1 mm thick, of radiately arranged mainly parallel hyphae more
densely compacted beneath the subhymenium and abhymenial surface, embedding a few
coarse crystals and in the subhymenial region bearing gelatinous granules; generative hyphae
3-5.5 µm diameter, walls 0.2 µm thick, hyaline, with conspicuous clamp connections.
Hymenial layer to 90 µm deep, a dense palisade of basidia and paraphyses, many encrusted
with mucilage granules. Basidia clavate, 26-35 x 6-7 µm, bearing 4 spores; sterigmata erect,
slender, to 5 µm long. Paraphyses subclavate, 18-28 x 4-5 µm. Spores narrowly elliptical or
allantoid, 5-6 x 2-2.5 µm, walls smooth, hyaline, 0.1 µm thick, nonamyloid.
Habitat: HABITAT: Bark or decorticated wood of dead branches.
Distribution: DISTRIBUTION: North America, New Zealand.
Notes: Collections agree with the description published by Cooke, the species being separated from
the closely related P. radiata Fr. by the absence of gloeocystidia.
