Bistre, xxix.). Bills adnate, moderately close, slightly vcirtricose, livid brown 
(near Fuscous, xlvi.), edges white. Stem 11 to 1 A in. (3.1 to 3.7 cm.), slender, 
equal, fragile, at first pallid and white pulverulent, then rufescent, shining. Spores 
ventrieose, one end more pointed, dark brownish-black microscopically, 9.5 to 13 
x 5.5 to 7.5 ,u (British specimens 12 to 15 x 7 to 9 m)- At the free edge of the 
gill is a row of small ventrieose or flask-shaped cystidia, 28 x 9 /t. Smell 
moderately strong. South Australia — In buffalo grass lawn, University, Adelaide; 
abundant in pastures, Port Lincoln. New South Wales. February, May.

PSATHYRA Fr. 
(Gr., psathyros, fragile.) 
“Pileus fleshy or submeinbranaceous, regular; margin straight, at first 
adpressed to the stem. Stem central, cartilaginous. Gills adnate adnexed or 
free. Spores purple, fuscous or cinereous purple; elliptical, oval or oblong 
elliptical; smooth with an apical germ-pore. Cystidia present. Growing on the 
ground or on wood, solitary or caespitose. ”■ — Rea. 
These are delicate, fragile fungi growing on the ground or on decayed wood 
with purple-brown spores, and correspond to Mycetui amongst the wliite-spored 
genera. The margin of the pileus is when young straight and adpressed to the 
stem, thus differing from some species of Psilocybe which otherwise may resemble 
members of this genus. Very few species of Psalliyra occur in this State, only 
two so far having been recognised. 
220. Psathyra Sonderiana Berk. (After W. O. Souder, the Hamburg botanist, 
author of the first volumes of the “Flora Oapensis”). — Pileus 4 to ljin. (1.2 to 
3.7 cm.), 1 to fin. (6 to IS mm.) high, conico-convex or conic, o-campamilate or 
broadly conical, then couico-expanded, rarely purely convex, usually subgibbous 
or even umbonate, rugose-striate or slightly striate at the periphery when moist, 
slightly atomate when dry, smooth, tending to fray at the edge, edge not turned 
in when young, markedly hygrophanous, Verona Brown (xxix.), Olive Brown 
(XL.) or near Bister (xxix.), drying first at the umbo through Saeeardo’s Umber 
(xxix.) to opaque whitish with a biscuity tint (near Cartridge Buff (xxx.), or 
Pinkish Buff (xxix.), the colour when moist sometimes obscured by delicate 
interlacing whitish fibrils. Gills adnate, moderately close, rather ascending and 
narrow, reaching the edge of the pileus, near Drab (xlhi.), paler and greyer 
than Snuff Brown (xxix.), darker than Bister (xxix.) or near Mummy Brown 
(XV.), becoming dark purplish brown (near the colour of the gills of ripe mush- 
rooms or more vinaceous than Verona Brown, xxix.), edges sometimes slightly 
paler and serrate. Stem 1 to -tin. (2.5 to 10 cm.), slender, equal or attenuated 
upwards, sometimes flattened, a little wavy, slightly striate or fibrillose, brittle, 
hollow, silky-white, flesh heterogeneous from that of the pileus. Spores dark 
bronze to bronzy brown, oblique, narrow, one side more flattened, 7.5 to 11 x 
4 to 5.5 n, no cystidia seen. Sometimes caespitose. On the ground, usually 
amongst grass, sometimes under trees. South Australia National Park, Lncioim- 
ter Bay. April, May, July, August. Plant's obtained amongst grass at Mount 
Gambler in May, though presumably the same species, are smaller (up to |in., 
l.S cm.), low convex, the pileus dark brown and striate when moist, pallid whitish 
when dry, spores dark bronze, one end broader, 7.5 to occasionally 9 x 4 to 5 y. 
F. SPORES BLACK OR BLACKISH-FUSCOUS. MELANOSPORAE. 
(a) Pileus distinct from and easily separable from the fleshy stem. 
*With a ring on the stem. 
ANELLARIA Karst. 
(L., anellus, a little ring.) 
“Pileus fleshy, campanulate. Stem central. Ring membranaceous, persistent 
nr fugacious. Gills adnate or often almost free. Spores black or blackisli- 
fuscous, pip-shaped or elliptical, smooth, with an apical germ-pore. Growing 
on dung or on the ground. ’ ’ — Rea,
