Description: Hymenophore resupinate, annual,
reviving a second season, membranous, adherent, effused forming linear areas to
30 x 1-1.5 cm; hymenial surface dark reddish-brown with a purple tinge,
velutinate, even, becoming deeply areolately creviced; margin thinning out,
definite, fibrillose, ferruginous, adherent. Context 150-250 µm deep, umber, of
loosely intertwined and parallel hyphae, bordered by a pseudoparenchymatous
cortex bearing short abhymenial hairs; generative hyphae 3-3.5 µm diameter,
walls 0.25-0.5 µm thick, golden-brown. Setal layer to 130 µm deep, of scattered
fascicles of 2-6 setae with single setae between, arising from the subhymenium;
setae subulate, apices acute, some projecting to 60 µm, 40-95 x 6-8 µm, walls
naked, deep reddish-brown, lumena narrow. Hymenial layer to 50 µm deep, a dense
palisade of basidia and paraphyses. Basidia subclavate or more often
cucurbitiform, 12-16 x 4-5 µm, bearing 4 spores; sterigmata arcuate, slender, to
6 µm long. Paraphyses subclavate, 10-12 x 5-6 µm. Spores elliptical, or obovate,
apiculate, 5-6 x 3-3.5 µm, walls smooth, hyaline, 0.2 µm thick.
Habitat: HABITAT: Bark of dead stems associated
with a white rot.
Distribution: DISTRIBUTION: Ceylon,
New Zealand.
Notes: Specimens agree with a
cotype collection from Ceylon in Kew herbarium, differing in that hyphae are of
slightly greater diameter and fascicles more scattered. Fructifications extend
for 30 cm upon dead stems, are closely adherent, with even surfaces coloured
dark reddish-brown with a purple tinge. The margin is concolorous and
fibrillose. Setae are sometimes arranged in slightly projecting fascicles of two
to six with solitary setae between; or may appear in a narrow setal layer
without evident fascicles. About half the basidia are cucurbitiform, the others
subclavate and narrower than the paraphyses. Spores are abundant, commonly
elliptical or some slightly obovate with lateral apiculi. Three species with
fasciculate setae have been described. H. lictor differs from H.
dictator by several features discussed under the latter; and the South
African H. fasciculata Talbot differs from both in its larger setae
arranged in fascicles of eight to twelve, stratose context, and dendriform
generative hyphae.
