CoPRiNus PMCATILOIDES Buller.- — Buller (Researches on Fungi, 

 1909, p. 69) describes a (frequently) minute Coprinus, resembling 

 C. [ilicatilis, under this name. He states that it grows on horse- 

 dung, and is often amongst the most tiny of the Agarics, being 

 sometimes only 1 cm. long, and 2 mm. wide. The average length 

 i.s 3 cm. (a little over an inch), with a cap 5 to 6 mm. wide. The 

 fruit-bodies are very delicate. He adds, that he considers it 

 undescribed, and that, though having a depressed disc at 

 maturity, like C. plicatilis, this is narrow and not broad, whilst 

 the gills are not attached to a collar, and the spores are oval. 



We have, on sevei-al occasions, collected a species which, from 

 the above description and Buller's figures, we believe to be this. 

 C. pphemerus, in Cooke's Illustrations, resembles our species, but 

 is larger, and has an elevated disc. Specimens collected on 

 horse-dung, at Sydney, in March, may be described as follows: — 

 Small. When young, conical, with fine, brownish granules, then 

 convex, \ inch in diameter, grey, centre depressed, coarsely 

 ribbed, covered with a few, tine, brown flakes. Gills 12 to 20 or 

 30 in number, narrow, distant, alternate ones short, fading 

 away as the stem is reached. Stem 1 inch or more high. Spores 

 black, 13"8-16 xB'J-O/i. Specimens collected in numbers, on 

 horse-dung, at Dubbo, in October, are very similar. The pileus 

 is at first uniformly covered with fine, brown scales; later, these 

 become scattered, revealing the paler brown, striate pileus. The 

 stem is white, and more or less fiufiy, or even radiately strigose 

 at the base. Spores 14-14-2 x 7-8-2/x. 



Coprinus angulatus (Lloyd, in " Mycological Notes," Dec, 

 1900, p.46). -^ "Pileus when young hemispherical, even, striate, 

 becoming convex and plicate-sulcate when mature, smooth, when 

 young white with ochreous tints, when partly grown dark grev 

 with a brown (somewhat hygrophanous) centre, thin, (lills rather 

 distant, reaching the stem, when mature (but before deliques- 

 cing) black with a white edge. Stipe pure white, equal, hollow, 

 striate, when very young evidently white scurfy, but appearing 

 glabrous when grown. Spores very peculiarly angular shape 

 like a keystone, I 4 x 9/x. On burnt ground, somewhat grega- 

 rious." — Lloyd.
