1?. Margin of fileils straight and addresser to tiif, stem at first. Stem 
cartilaginous. Mycelium kiiizomokpuoid, corticate. 
259. Marasmlus equicrinis F.v.M. (L., cquvs, ;i horse; crvrm, hair). — Pileus 
1/16 to Jin. (1.5 to 3 him.), convex or hemispherical, with about. 8 coarse rugae, 
umbilicate with a minute dark knob in the centre of the dimple, near Tawny 
Olive (XX ix.). (Jills adnnte, attached to a collar, S to II in number, distant, 
pallid. Stem 1 to 5in. (2.5 to 12.5 cm.), often less, smooth, hair-like, abruptly 
piercing the matrix or arising at right angles from the mycelium, dark brown 
or black, pallid below the pileus. Sterile mycelium tough like horse-hair, brown, 
tangled amongst fallen leaves, etc. Spores elongated, elliptical, 7.5 to 9 x 4.51 to 
5.5 fi. South Australia — Mount Lofty, Greenhill Road, National Park. New 
South Wales. March to July. 
The Horse-hair Fungus is not uncommon amongst the debris of fallen leaves 
in shaded forests. The sterile mycelium is often abundant and careful search 
may show the minute caps on long hair-like stems. 
*' Pileus with a thick cellular pellicle. 
tCells of the pellicle upright, echinulate or verrucose. 
ANDROSACETJS (Pers.) Pat. (MARASMIUS Fr., in part). 
(Gr., andro.%ik<!s, an unidentified sea-plant.) 
“Pileus membranaceous, thin, regular, cells of pellicle echinulate or tuber- 
culoae. Stem central, horny. Gills adnate, emarginatc, decurtrent or attached 
to a collar. Spores white, elliptical, pip-shaped, oblong elliptical, subglolmse or 
club-shaped; smooth; continuous. Cystidia present or absent. Growing on 
wood, fallen leaves, etc.’’ — Rea. 
260. Androsaceus alveolaris del. ( L., alveolar in, alveolar, having little troughs 
or depressions). — Pileus Jin. (3 mm.) or less, rarely more, the surface alveolar 
from raised ribs rimosely arranged, leaving a polygonal cell in the centre, dark 
honey-coloured (near Snuff Brown, x.xix.), the ribs darker. Gills adnate, distant, 
6 to 10 in number, with some venose elevations at the periphery forming abortive 
gills and buttressing folds, edges thick, pallid honey -coloured. Stem short, up 
to Jin. (6 mm.), rarely more (Jin., 15 mm.), slightly pruinose, whitish above, 
very dark brown below, abruptly entering the matrix. Spores white, narrow, 
oblique, witli the ends drawn out and acute, 10 to 13 x 5.5 a, 9 to 10 x 3.7 /t. 
Hairs on the pileus and stem colourless, straight with knobby or irregular swollen 
apices, 38 to 76 x 7.5 fi, forming a villous coat, a few; present also on the edges 
of the gills. On bark. South Australia — National Park, Encounter Bay. May, 
July. 
This little fungus, described as Marasmius alveolaris, seems better placed under 
Androsaceus. 
1 1 Cells of the pellicle decumbent, very long, librillose. 
CRINIFELLIS Pat. 
(L., erinis, hair; pelUs, skin.) 
“Pileus membranaceous, regular, cells of pellicle long, thick, tough. Stem 
central, firm. Gills adnate or free. Spores white, pip-shaped, smooth or punctate, 
continuous. Growing on wood, twigs, etc, ’ ’ — Rea. 
261. Crinipellis caulficinalis (Bull.) Rea (Gr., Inulos, a stalk). — Pileus Jin. 
(1.2 cm.), irregularly convex, covered with intricate adpfiessed fibrils, edge some- 
times slightly rugose, pallid brownish drying to a pale greyish brown or dead 
grass colour. Gills apparently adnate or admixed or attached to an indefinite 
collar, then seceding, moderately close, eoneoUirous. Stem up to 1 ill . (2.5 cm.), 
slender, usually attenuated downwards, densely pilose, solid, eoneoiorous or some- 
times browner. Spores elongated pear-shaped, one end pointed, 10.5 x 5 /t. 
Caespitose on the ground, often attached to burled grass stems. South Australia — 
Hill near Beaumont (Adelaide). April. 
Specimens, apparently this species, from Neutral Bay, Sydney, March, have 
a tinge of purple on the pileus and stem and spores 7 to 8.5 x 4.4 to 5 /*. The 
representation of < 7 . caulu'iiiMis in Bresadolu ’s Icunographia Mycologies, Tab. 
496, 2, docs not; give a good impression of the Australian plant that we refer to 
this species.
