This variety does not differ from the type sufficiently to warrant 
its being placed as a species ( C . subbotrytis Schmidle). Moreover, 
the zygospores are precisely similar to those of the typical form.

We are a little uncertain exactly where to place this plant ; it is cer- 
tainly not G. Broomei Thwaites, nor is it G. pseudobroomei Wolle, and 
is a species we have not previously observed. It appears to be nearer 
to Schmidle’s species (in Ber. d. Nat. Gesellsch. Freiburg, Bd. vii. 
Heft i. p. 104, t. v. f. 22-24) than any other, but the granules are 
more numerous, and those in the centre of the semi-cells do not 
project so prominently when seen in vertical view.
