Brachyglottis repanda Forst. Auckland: Clevedon, 150ft, August 1949, J.M.Dingley. Leptospermum ericoides A.Rich. Auckland: Great King Island, Three Kings, January 1952, E.E.Chamberlain; same locality, December 1955, P.J.Brook. Leptospermum scoparium Forst. Auckland: Rereatukahia Reserve, Katikati, 300ft, September 1954, G.H.C., type collection, P.D.D. herbarium, No. 16604. Myrtus pedunculata Hook.f. Auckland: Woodhill, 100ft, July 1953, J.M.Dingley.

Hymenophore resupinate, annual, membranous, adnate, at first appearing as numerous small elliptical colonies 1-2.5 cm long, merging to form effused linear areas 5-20 x 1-2.5 cm. Hymenial surface at first olivaceous, becoming reddish-brown, velutinate, tardily laterally creviced; margin thinning out, adnate, fibrillose, fulvous or concolorous. Context ferruginous, 70-130 µ thick, of mainly upright hyphae becoming partly cemented and somewhat cellular when old, embedding setae and coarse irregular crystals; hyphal system monomitic; generative hyphae 2-2.5 µ diameter, walls 0.5 µ thick, golden yellow, branched, septate. Setal layer at first confined to a single row arising from the abhymenial zone, in older plants composed of 3-5 overlapping irregular rows; setae projecting to 140 µ, acicular, 95-190 x 8-12 µ, walls naked, reddish-brown, sometimes embedded in hyphal sheaths, lumina narrow. Hymenial layer to 30 µ deep, a close palisade of basidia and paraphyses. Basidia subclavate, 18-24 x 5-6 µ, 4-spored; sterigmata arcuate, slender, to 7 µ long. Paraphyses subclavate, shorter and narrower than the basidia. Spores suballantoid, 8-9 x 3.5-5 µ, walls smooth, hyaline, 0.1 µ thick.

DISTRIBUTION: New Zealand

HABITAT: Effused on bark of dead branches associated with a pocket rot.

Resupinata, annua, membranacea, adnata. Superficies hymenii primo olivacea deinde brunneo-rubra, tarde rimosa; margine fulvo vel concolori, fibrilloso, adnato. Contextus ferrugineus, hypharum maxime erectarum, partim conglutinarum; cortex abest. Hypharum systema monomiticum. Setarum stratum 3-5 ordinibus, acicularibus, nudis, 95-190 x 8-12 µ, partim superimpositis, ad 140 µ eminentibus. Basidia subclavata, 18-24 x 5-6 µ, 4 sporis sub-allantoidibus, 8-9 x 3.5-4.5 µ.

Separated from other species placed under Section III by the large setae and spores. At first fructifications consist of a thin cemented layer lying upon the substratum. From this the setae arise; at first in a single row, in older plants setae are arranged in several overlapping rows embedded in intertwined hyphae. The hymenial surface of young plants is olivaceous with a narrow fulvous border; in older specimens, because of the projecting setae it becomes velutinate and reddish-brown with a reddish tinge. Spores vary in form, even in the same collection. They may be elliptical or suballantoid, and in diameter range from 3-5 µ to 4-5 µ, though fairly constant as to length.
