Introduction. 
I N May, 1901, Professor Marshall Ward handed to me for 
investigation three species of Gymnoascus , which had 
been received by him from Mr. Massee, who had collected 
them on the substrata referred to below. The species were 
(1) G. Reessii (Baranetzky), growing on dung, of what kind 
could not be determined ; (2) G. setosus (Eidam), on an old 
bee’s nest ; and (3) G. candidus (Eidam), Arachniotus candidus 
(Schroeter), on dead grass. Subsequent examination showed 
that all three species were growing together on the old nest. 
The total number of species of Gymnoascus actually known 
is probably about a dozen. Winter 1 , in Rabenhorst’s Krypto- 
gamen-Flora, describes G. Reessii, G. ruber, and G. uncinatus. 
Massee 2 mentions G. Reessii and G. ruber (van Tieghem), but 
does not notice any other species as found in Britain. 
Fischer 3 mentions five species, viz. G. Reessii, G. setosus 
(Eidam), G. durus (Zukal), G. umbrinus (Boudier), and G. Bour- 
queloti (Boudier). Saccardo 4 , in 1889, describes six species
