ON HETEROSPORIUM. 
By M. C. Cooke. 
In the course of a communication on the Dematiei, read before 
the Quekett Microscopical Club, on Friday, the 23rd February, 
some observations were made on the species of Hehmntliosporium, 
with echinulate spores. It was observed that many years since 
Klotsch distributed some specimens of one of these moulds on 
Ornithogahim, under the name of Heterosporiiim ornitliogali, lO. 
This genus, it was contended, should be maintained for the species 
allied to this on Ornithogahim, of which three or four are known, 
and amongst these, Helminthosporium echinidatum, B. & Br. The 
genus does not appear to have been described, but may be charac- 
terised as follows : — 
Hetezospozium. Klotsch. 
Flocci erecti, septati, flaccidi. Sporis heterogenis, deciduis, 
demum multiseptatis, subhyalinis, echinulatis vel granulatis.
