The well-known Stropharia semiglobata is evidently a common fungus in 
the Falklands, several tubes collected on various occasions being forwarded. 
In one gathering (no. 6) the specimons were so large as to render doubtful 
their identity with the true ©. semiglobata. On this account а somewhat 
detailed study of fresh British specimens was undertaken, the size of the 
spores, together with other microscopic characters, being specially noted. 
The results with regard to spore-variability have already been published (see 
Trans. Brit. Мус. Soc. 1913, pp. 298-300). The Falkland Islands specimens 
agreed exactly in microscopic characters with the English, and the two 
plants are clearly identical, the large size attained by some of Mrs. Vallentin's 
specimens being equalled occasionally in English gatherings.

There is no type of C. floscula in existence, but Berkeley’s original drawings 
are at Kew. These seemed so clearly to portray С. radiatus, one of the 
commonest dung-fungi in Europe, that I sent copies of the drawings and 
descriptions to Prof. A. Н. В. Buller for confirmation. Prof. Buller replied 
that Coprini are well-known to be widely distributed, and that he saw “ no 
ground whatever for making it a distinct species."

The present very pretty species closely resembles P. atomata, having the
