Article: Cunningham, G.H. (1963). The Thelephoraceae of Australia and New Zealand. New Zealand Department of Scientific and Industrial Research, Bulletin 145: 359 p. Wellington:. Description: Hymenophore annual, coriaceous, commonly solitary. Pilei
infundibuliform, 10-15 mm radius, 10-15 mm tall; pileus surface concentrically
zoned with colour bands of bay, chestnut or tobaccobrown, sometimes grooved
slightly, glabrous or pruinose; margin acute, usually incurved, pruinose,
concolorous, entire. Stems to 5 x 2 mm, smooth, pallid brown. Context wood
colour, 200-350 µm thick, without a cortex or abhymenial hairs, of densely
arranged parallel hyphae; skeletal hyphae to 4 µm diameter, walls 1-1.5 µm
thick; generative hyphae 2-2.5 µm diameter, walls 0.2 µmthick, with clamp
connections. Gloeocystidia arising in the base of the subhymenium and traversing
the hymenial layer, flexuous-cylindrical, 48-120 x 6-10 µm; sometimes inflated
at bases. Hymenial layer to 120 µm deep, a dense palisade of basidia,
paraphyses, and gloeocystidia. Basidia subclavate or subcylindrical, 22-30 x
4.5-6 µm bearing 4 spores; sterigmata slender, erect, to 4 µm long. Paraphyses
subclavate, 12-25 x 4-4.5 µm. Spores broadly elliptical, apiculate, 7-9 x 4.5-6
µm, walls smooth, hyaline, 0.1 µm thick.
Habitat: HABITAT: Usually solitary on
the ground among grass.
Distribution: DISTRIBUTION:
Australia, South Africa.
Notes: Separated
from other species with central stems and dimitic hyphal systems by the large
spores, absence of a coloured cortex, and glabrous exterior. Only the type has
been recognised from this region, although there is a second collection in Kew
herbarium ex "Australia, R. Brown" filed under the cover of S. nitidulum
which resembles the type but is sterile. The description has been drawn
from the type, which consists of three specimens. Lloyd (1923, p. 1226) recorded
the species from Tasmania. Part of this collection, now in the herbarium of J.
B. Cleland, when examined was found to consist of specimens of S.
elegans.
