respectively ; and describes the conidia as spherical, 3 » in diameter ; 
otherwise the agreement is close). 
This fungus grows well on honey agar, prune decoction agar, 
and apple; on the other media tried it either grew poorly or produced 
much sterile mycelium. Gelatine was invariably liquefied; conse- 
quently the fungus did not do well on gelatine media. No acid was 
produced. ; 
Crookshank (7, p. 588) remarks that ‘‘ bread and potatoes 
acquire a reddish-brown colour’’ when A. nidulans is cultivated on 
them. This was verified in both cases; but my fungus did not do 
well on either substratum. The effect was also observed in the case 
of apple, which was, turned a dark-red brown; and a tendency to a 
darkening of the medium was also noticed in a culture on sugar 
solution with litmus. 
Citromyces glaber, Wehmer. 
This species was originally obtained from a living stock, but 
has since been cultivated from material from dead stocks, and is 
probably common in hives.

The conidiophore is 2.5—3 p in diameter, septate, rarely if ever 
branched. The apex is slightly inflated, 5—8 «in diameter. The 
sterigmata are elongated oval, pointed at their distal ends, directed 
parallel to the long axis of the conidiophore, 10 x 3 (Fig. 15). The 
conidia are spherical, smooth, 2.3 » to barely 3 p in diameter, often 
forming long chains. Bodies probably of a sclerotial nature were 
met with in one culture on prune decoction agar. They were oval,
