THE LARGER FUNGI 
The chief features of the genus consist in the pileus, at first conical or 
campanulate, being innately silky, tibrillose or fibrillose-scaly, the cuticle con- 
tinuous to the stem as a more or loss evanescent - fibrillose eortina, the gills and 
spores pallid dull brown, the smooth spores and the frequent presence of 
cystidia on the gills. The fungi are relatively small and terrestrial. Only a 
few species of Inocybe and of the allied Astrosporina with angular spores are 
known from South Australia. Though never abundant, individuals are not 
uncommon on the Mount Lofty Ranges.

157. Inocybe serrat.a del. (L . ser ratios, toothed like a saw). — Pileus tin. 
(1.2 cm.), convex, fibrillose, near Verona Brown (xxix.), pallid brown or colour 
of dead grass. Gills adnate, edges serrate and sometimes paler, near Snuff 
Brown (xxix.) or Wood Brown (xu). Stem f to Ijin. (1.8 to 3 cm.), slender,

13 p. The plants are deep brown when dry. Gregarious to subcaespitose with 
villous bases. South Australia — Mount Lofty, Upper Tunkalilla Creek. April, 
J une. 
The species seems closelv related to /. flooculoxa Berk, but differs in the serrate 
gills.

August.
