Description: Hymenophore annual, membranous, loosely
attached, effused forming irregular areas 4-10 x 2-5 cm, with a few scattered
orbicular outlying islands; hymenial surface umber with broad fawn margins, at
first somewhat porose, becoming even or slightly tomentose, not creviced; margin
thinning out, to 5 mm broad, fawn, adherent. Context ferruginous, to 200 µm
thick, basal layer containing numerous cordons 10-25 µm diameter of 5-10 hyphae
closely compacted, intermediate layer of loosely intertwined mainly ascending
hyphae; generative hyphae 3-5-4 µm, diameter, walls 0.2 µm thick, pallid
yellow-brown, with clamp connections. Hymenial layer to 40 µm deep, a loose
palisade of basidia, paraphyses, and paraphysate hyphae. Basidia clavate, 16-28
x 4-6 µm, bearing 4 spores; sterigmata slender, arcuate, to 5 µm long.
Paraphyses subclavate, 12-18 x 4-5 µm. Paraphysate hyphae projecting to 60 µm,
clavate, 52-96 x 6-8 µm, apices inflated to 12 µm, with one or two transverse
septa each with a clamp connection. Spores oval or irregularly subglobose,
angled, apiculate, 7-9 x 6-7 µm, walls strongly sinuate, finely irregularly
verruculose, yellow-brown, 0.2 µm thick, spines to 0.5 µm long.
Habitat: HABITAT: Lower surfaces of pumice boulders lying upon the ground.
Distribution: DISTRIBUTION: North America, France, New Zealand.
Notes: Cordons are abundant in the base, and composed of few or
many thin-walled hyphae firmly compacted. Paraphysate hyphae ('cystidia' of
Burt; 'cystidioles' of Bourdot & Galzin) project for as much as 60 µm, and
possess one or two transverse septa each with a clamp connection. Walls are
hyaline, 0.25 µm thick, and even or bear a few mucilage granules.
