Brachyglottis repanda Forst. Auckland: Taneatua Reserve, 50ft, May, 1952, G.H.C., type collection, P.D.D. herbarium, No. 11484 Hedycarya arborea Forst. Auckland: Lake Okataina, 1,400ft, June, 1951, J.M. Dingley. Weinmannia racemosa L.f. Wellington: Ohakune, 2,000ft, December, 1953, J.M. Dingley.

Hymenophore annual, sometimes biennial, membranous, adnate, effused forming irregular linear areas 12-15 x 3-5 cm; surface dingy white or pallid cream, velutinate, not creviced; margin thinning out, membranous, adnate, sometimes tending to lift. Context white, 50-130 µ thick, basal layer narrow, of parallel hyphae, intermediate layer scanty, of closely compacted hyphae collapsed when old, many crystal coated; generative hyphae 2.5-4 µ diameter, walls 0.2 µ thick, hyaline, branched, septate, with inconspicuous small clamp connexions. Hymenial layer to 35 µ deep, an irregular palisade of basidia, paraphyses, paraphysate hyphae and cystidia. Basidia subclavate or subcylindrical, projecting, 20-25 x 7-9 µ, 2-4-spored; sterigmata arcuate, to 8 µ long. Paraphyses scanty, subclavate, to 18 x 7 µ. Paraphysate hyphae abundant, projecting to 18 µ, 2-3 µ diameter, each bearing a cap of acicular crystals. Cystidia arising from the base of the intermediate layer, emerging for the greater part of their length, subulate, 120-210 x 12-16 µ, bases rounded and inflated; apices long-acuminate, thick-walled, rugulose-roughened or etched, sometimes with a few crystals and enclosed within a sheath of delicate hyphae. Spores globose, subglobose, oval sometimes broadly elliptical, 7-11 x 6-9 µ, strongly apiculate, walls smooth, hyaline, 0.25 µ thick.

DISTRIBUTION. New Zealand.

HABITAT. Effused on bark of dead branches.

Hymenophoram annuum vel biennale, membranaceum, adnatum, effusum; superficie griseo-alba vel pallide cremea, velutina, non rimosa. Hyphae contextus fibulatae, 2.5-4 µ diam., nudae. Basidia subclavata vel subcylindricalia, eminentia, 20-25 x 7-9 µ, 2-4 sporis. Hyphae paraphysum apice crystallis coronatae. Cystidia subulata, eminentia, 120-210 x 12-16 µ, caelata, velut si crystallis tenuibus tecta. Sporae globosae, subglobosae vel ovales, 7-11 x 6-9 µ, laeves, hyalinae.

Among the species with radicate cystidia, P. gladiola and P. hastata are outstanding, none approaching them having been seen in Kew herbarium. Cystidia are subulate, project far beyond the delicate context, walls are thickened, become partly disorganized in KOH, and are rugulose-roughened as if etched, rather than crystal coated. Frequently they are enmeshed in a hyphal sheath as in P. vermifera.
P. gladiola is differentiated by the large basidia, subglobose or oval smooth spores with granular contents, and presence of paraphysate hyphae. The last are slender, project, and bear on their apices caps of acicular crystals. They may be plentiful or scanty in different collections, but are always present. Basidia sometimes bear two spores which are slightly larger than those from the tetrasporous forms.
