.] to Jiu. (15 to S mm.), occasionally up to Jin. (1.8 nun.), convex, sometimes 
llalielliform or kidney-shaped, later more flattened, faintly striate, villous-looking

Australia — Mount Lofty (record doubtful). New South Wales. March to Jul\. 
These little brown agarics, growing often in numbers on bark, are apt to be 
looked for under the genus Crei>idolit,s. It will be noted, however, that the short 
slender incurved stem is usually more or less centrally placed, tin 1 incurving of 
the stem being responsible for the apparently somewhat lateral attachment of 
the pileus. 
**Gills ndnate, pileus convexo-plane. 
No South Australian species recorded. 
***Gills ndnate, pileus eampanulate, then expanded.
