Hymenochaete dura Berk. & M.A. Curtis 1868 [1869]
CUNONIACEAE. Weinmannia racemosa: Westland, Weheka, 200 m. MIMOSACEAE. Acacia dealbata: Victoria, Kallista, Dandenong Ranges. ROSACEAE. Rubus schmidelioides: Otago, Horseshoe Bay, Stewart Island.
Hymenophore annual, membranous, umbonate-sessile, or resupinate, loosely attached save at the umbo, effused, appearing as numerous small orbicular colonies 3-10 mm diameter, which may merge peripherally to form irregular areas to 3.5 cm long; hymenial surface bay, tan, chestnut, or ferruginous, sometimes velutinate or fibrillose, not creviced but often slightly compressed in the centre; margin thinning out, concolorous, somewhat lighter in colour in young specimens, fibrillose, loosely attached, sometimes bluntly rounded. Context ferruginous, 0.2-0.45 mm thick, of radiately arranged mainly parallel hyphae, cortex dense, chestnut, bearing numerous abhymenial hairs; skeletal hyphae 3-4 µm diameter, walls 0.5 µm thick, pallid yellow-brown; generative hyphae 2-2.5 µm diameter, walls 0.25 µm thick, hyaline. Setal layer to 80 µm deep, a narrow area of 1-3 overlapping rows of somewhat sparse setae irregularly inserted; setae irregularly fusiform or cylindrical with bluntly acuminate apices, often curved or bent, some projecting to 30 µm, 30-60 x 5-8 µm, walls sometimes verruculose near apices, yellow or pallid chestnut, with broad or narrow lumena. Hymenial layer to 30 µm deep, a somewhat sparse palisade of basidia, paraphyses, and paraphysate hyphae. Basidia subclavate, 12-16 x 3-4 µm, bearing 2-4 spores; sterigmata slightly arcuate, slender, to 4 µm long. Paraphyses cylindrical, 8-12 x 3-3.5 µm. Paraphysate hyphae sparse or abundant, filiform, usually hyaline, projecting to 20 µm. Spores elliptical, 4 x 2 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Cuba, Australia, New Zealand.
HABITAT: Bark of dead erect stems associated with a white rot.
Collections agree with the type of H. dura in Kew herbarium, ex "Cuba, C. Wright, No. 241", differing in the thinner context and slightly narrower skeletal hyphae. Setae resemble those of the type, and are unusual in their irregular shape, bluntly acuminate apices, and presence of occasional false septa. Numerous filiform paraphysate hyphae project and give to the hymenial surface its fibrillose appearance, a condition also present in the type.
Spores were not found in the type. Burt (1918b, p. 353) gave measurements as 5 x 3 µm for a cotype specimen he examined. In collections from this region they are scanty, for although basidia were present in some 20 sections examined, attached spores were seen only in two. These were narrowly elliptical, 4 x 2 µm. Setae were sparse in portion of the type examined. In collections listed they were found to be sparse or abundant, being crowded in the central part, progressively more scanty towards the periphery. Burt (1918b, p. 352) described, paraphysate hyphae as paraphyses; the latter are, however, narrower and shorter than the basidia and do not project.
