The species are ciiaructeriscd by the white spores, the central stem whose flesh 
is continuous with and similar to that of the pileus, the more or less decurrent 
gills not emarginate near their attachment, and the edge of the pileus interned 
when young. The species are mostly medium to large in size, fleshy, growing e:;. 
the ground or amongst decaying leaves or fallen hark, rarely on wood. The 
colour of the pileus is usually whitish, greyish or brownish, rarely brightly 
coloured, and in many species the colour changes markedly on drying, i.e., the 
pileus is hygrophanous. It may be thin and the centre may become depressed, 
nmbilicate or deeply funnel-shaped. The gills are usually white, in some cases 
greyish or pallid-brownish, and more or less decurrent, rarely adnate and always 
without any haying at their attachment. The stem is sometimes very hollow, 
and in some specimens of a collection may not be quite centrally placed though 
central in others, and the spores are mostly small. 
As yet in this State not many species have been differentiated. Some of those 
known are, however, common. Thus usually amongst grass a drab-coloured species 
(('. pdraditopa), becoming pallid when dry, may oe readily recognised hv its 
strong smell of wattle-blossom. Another thinner drab-coloured species (C. brunneo- 
ceracea), also hygrophanous, occurs under pines. A whitish species, drying 
rather biscuit-coloured (C. xemiovnd ta) , is often numerous partly hidden (hence 
its name) under fallen Eiieiduptus hark. Other species grow under trees or in 
groups on grassy hills.
