Brachyglottis repanda Forst. Auckland: Hick's Bay, 300ft., May, 1952. G.H.C., type collection, P.D.D. herbarium, No. 11474. Pittosporum sp. Auckland: Whakapapa, Mt. Ruapehu, 3,000ft., October, 1949, J.M. Dingley.

Hymenophore annual, adnate, membranous, effused, forming linear areas to 40 x 3 cm. with numerous outlying islands; surface cream, even, not creviced; margin thinning out, white, arachnoid, adnate. Context white, 40-80 µ thick, composed of a narrow basal layer of parallel hyphae, and an intermediate layer of erect hyphae sparsely branched below, freely branched (corymbose) beneath the hymenium; generative hyphae 4.5-5 µ diameter, wall 0.5 µ thick, naked or occasional hyphae coated with fine crystals, hyaline, septate, without clamp connections. Hymenial layer to 40 µ deep, of basidia and paraphyses compacted into a dense palisade. Basidia subclavate, slightly projecting, 16-20 x 4-5 µ, 4-spored; sterigmata slender, to 4 µ long. Paraphyses subclavate, similar to the basidia but narrower. Spores obovate or elliptical, with rounded apex and acuminate base, 6-7 x 3-3.5 µ, apiculate, wall smooth, hyaline, 0.2 µ thick.

DISTRIBUTION. New Zealand.

Hymenophorum membranaceum, adnatum, effusum; superficie cremea aequa, non rimosa. Hyphae contextus in corymbis ordinatae, afibulatae, 4.5-5 µ diam., nudae. Basidia 16-20 x 4-5 µ, 4 sporis. Sporae obovatae vel ellipticae, 6-7 x 3-3.5 µ, laeves, hyalinae.

In the type collection the hymenophore is closely adnate, with an even, non-creviced cream surface, thin context with hyphae scantily branched below, corymbose beneath the hymenium, arising from a narrow basal layer of parallel hyphae, naked save for occasional hyphae which are finely crystal coated. The collection from Pittosporum differs in that the fructification is loosely attached, has a deeply creviced surface, hyphae are thinner, with thinner walls, and the basal layer is stouter. Occasional hyphae bear crystals, but most are naked. When further collections come to hand it may prove to be distinct.
