Description: Hymenophore annual, membranous,
adherent, effused forming linear areas to 6 x 1 cm; hymenial surface white,
even, becoming deeply laterally creviced; margin thinning out, white, arachnoid,
adherent. Context to 80 µm thick, basal layer of a few repent hyphae,
intermediate layer of loosely intertwined hyphae branched at a wide angle;
generative hyphae 2.5-3 µm diameter, walls 0.25-0.5 µm thick, naked, sometimes
inflated between septa, with clamp connections. Hymenial layer to 20 µm deep, a
close palisade of basidia and paraphyses. Basidia subclavate, 10-18 x 4-7 µm
bearing 4 spores; sterigmata slender, to 8 µm long. Paraphyses pyriform, a few
fusiform or subclavate, 6-10 x 4-5 µm. Spores elliptical, obovate with rounded
apices and attenuate bases, a few suballantoid, apiculate, 7-8 x 3-3.5 µm, walls
smooth, hyaline, 0.2 µm thick; sometimes adhering in fours.
Habitat: HABITAT: Effused on
rhizomes or dead pendent stipes of tree ferns.
Distribution: DISTRIBUTION:
Western Europe, New Zealand.
Notes: At
first milk-white, the surface of the hymenophore when old may become pallid
cream or occasionally pallid mauve. Specific features are the thin context with
scanty, widely branched hyphae, shallow hymenial layer, small broad basidia,
pyriform paraphyses with acuminate apices, and elliptical or obovate spores.
Here found on dead pendent stipes of tree ferns and rhizomes of climbing ferns,
in France it has been collected on stipes of Pteris aquilina growing in
a similar humid habitat.
