Descriptions
Hymenochaete lictor Petch 1925
ONAGRACEAE. Fuchsia excorticata: Auckland, Lake Okataina, 500 m. POLYGONACEAE. Muehlenbeckia australis: Otago, Taieri Mouth, 70 m.
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.
DISTRIBUTION: Ceylon, New Zealand.
HABITAT: Bark of dead stems associated with a white rot.
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.
TYPE LOCALITY: Ceylon.
