and telephone poles and over buried wood, sometimes for some while after the 
removal of the wood. South Australia — Adelaide district. New South Wales. 
Victoria. April, June, September. (Figure 30.) 
the situation (near old wood), densely caespitose habit, micaceous granules 
on the yellowish brown pileus, white stem and absence of a ring make this 
suhdeliquescent species of Coprinun easily recognisable. The smaller Pmthiffella 
disseminata resembles it. 
““’“Pileus smooth, without floccose Or micaceous squamules. Veil none. 
No South Australian species recorded. 
II. Pileus very thin, without a pellicle, at length opening into furrows along 
the back of the gill s and becoming plicato-sulcate. Stem thin, fistulose. 
Gills melting away into very thin lines. 
*Stem annulate, or volvate. 
No South Australian species recorded. 
**Pileus clothed with superficial separating fioceules. Gills free. Ringless. 
No South Australian species recorded. 
‘"Pileus micaceous or furfuraeeous. Gills commonly adnate to the apex

to 8 p. On dung. South Australia — Adelaide. September. 
Bea, in “British Basidiomycetae, ’ ’ states that the disc of C. ephemerus is 
elevated and often umbouate and that the spores measure 8 t'o 10 x 55 to 8 p 
Our species may be C. c.urtus Kalelib. (= C. pUcatOoules Buller.).
