Coprophilous Fungi. II. 
Bab. — On the dung of Sinaitic Ibex ( Capra sinaitica) and 
Common Camel, Kew, Feb. 1901. (Distrib. — Finland, on dung of 
Field-mouse.) 
The differently shaped spores, furnished with distinct warts, appear 
important enough characters to separate the above specifically from 
»S. Stemonitis (Pers.), Corda. As mentioned above, Karsten’s 
‘ 6*. Stemonitis under which the present plant was originally described 
as a variety, is not Persoon’s species as described by Corda and other 
authors. The spores of S. fimetarius under a high magnification are 
seen to bear short raised lines or ribs, which give them a warted 
appearance. 
Tubercularieae. 
Amerosporae. Chaetostroma, Corda, in Sturm’s Deutschl. FI., 
i, 122 (1829); Sacc. Syll. Fung, iv, 749 (1886). 
Sporodochium discoid or pulvinate, becoming black, with a marginal 
fringe of long, dark-coloured setae; conidiophores filiform, simple, 
closely crowded side by side; conidia elliptical or subglobose, con- 
tinuous, coloured, solitary and acrogenous. 
The present genus is very closely allied, morphologically, to Volutella, 
Tode, differing only in the blackish colour of every part. The last- 
named genus in turn is scarcely distinct from Vermicularia , Fries, in 
which the most highly organized species have a distinct peridium 
covered with bristles and furnished with a definite opening or ostiolum 
at the apex, through which the conidia escape at maturity. From 
this type there is a gradual reduction of the wall of the peridium 
through several species, until finally the peridium is reduced to a mere 
spinose rim surrounding the fertile disc as in Chaetostroma , from 
which such species of Vermicularia differ only in the colourless 
conidia. It is to be noted, also, that the reduced type of Vermicularia 
just described only differs from typical species of Volutella in having 
the spines black instead of colourless.
