Brown, or Mikado Brown (xxix.) becoming paler. Gills adnate to adnato- 
decnrrent, narrow, moderately close, edges sometimes irregularly serrate, rarely 
forking or anastomosing near the stem to form long narrow cell's, Light Pinkish 
Cinnamon (xxtx.). Stem H to 24in. (3.7 to 6.2 cm.) high, stout (up to -Jin., 
2.2 cm. thick), base swollen ( 1 in., 2.5 cm., thick), sometimes a little excentrie, 
somewhat mealy or fibrillose, Solid, pale fawny or biscuitv whitish or white. 
.Flesh watery semi-translucent becoming whitish. Slight smell of radishes. Spores 
obliquely pear-shaped, rather irregular, definitely tinted, 6.5 to 9 x 4.2 to 6 p. 
Densely caespitose under trees or amongst grass. South Australia — Mount Lofty 
Range, National Park. Victoria — Ararat. April to August. 
104. Clitopilus prostratus Clel. (L., prostratus, lying fiat). — Pilous J to lin. 
(1..N to 2.5 cm.) in diameter, very irregular, more or less convex- with the centre 
depressed, somewhat rugose, somewhat fibrillose, edge sometimes crinkled, colour 
of dead grass. Gills decurrent, moderately close, relatively deep, pallid salmon- 
coloured. Stem short (1 cm.), central to excentrie, slender, surface matt, whitish. 
Spores angular with a central yellowish gutta, tinted, 9.5 to 10.5 x 7.5 p. South 
Australia — Nearly prostrate on bare sandy soil in heathy scrub near Mount Burr 
(S.E.), Encounter Bay district, Kinehina. May, June. 
In Encounter Bay specimens, the flesh of the stem is noted as being cartilaginous 
and differing in texture from the pallid flesh of the pileus. If this is confirmed, 
the species should be transferred to Kcci.Ua. 
A small short-stemmed drab-coloured species resembling the common Cantharclliin 
Jmmneuft, but the gills are a dingy salmon colour and do not tend to fork. 
105. Clitopilus australiana Clel. (L., Amiralianus, Australian).- — Pileus ljin. 
(3 cm.), convex, centre dimpled, pale brown. Gills slightly decurrent, close, pale 
brownish. Stem lin. (2.5 cm.), fibrillose, pallid. Spores pear-shaped, slightly 
angular, faintly tinted, 6.5 to 7 x 5.5 p. South Australia — National Park. July. 
(<?) Pileus confluent with but heterogenous from the cartilaginous stem. 
*Gills sinuate or sinuat'o-adnate. 
Margin of pileus at first incurved or exceeding the gills. 
LEPTONIA Fr. 
(Gr., lepton, thin.) 
"Pileus slightly fleshy, regular, margin incurved. Stem central, cartilaginous. 
Gills adnate, sinuato-adnnte or adnexed. Spores pink; angular, elliptical, sub- 
globose or oblong; continuous. Cystidia rarely present. Growing on the ground 
or on wood.” — Rea. 
The plants are usually small and slender-stemmed with an umbilicate pileus 
when mature and the edge of the pileus in-turned when young. The gills are 
adnate or adnexed, seceding when old, and their original colour in the young 
state becomes obscured by the salmon-tint of the spores as they mature. Our 
ten or more species are in no instances numerous, being found as scattered 
individuals in sandy soil or damp places, all on the ground. The pileus and stem 
are in many of our species drab, brown or blackish ; in two the blackish stem 
has a steel-blue or violet tint giving a beautiful effect. Another elegant species 
is tlie green L. viridc-marginata.
