BETTS : THE FUNGI OF THE BEE-HIVE. I41 
Gymnoascus ruber, Van Tieghem. 
This species has only once been met with; it was growing on 
the dead cluster in a stock which died out during the winter of 
tgtt-12. The fungus formed dull brick-red tufts on the dead bees or 
on the edges of the cells where they are clustered. 
The hyphae vary in size and appearance; they are branched in 
an irregular manner, are apparently not rigid, and do not end in 
hooks or spines. They are usually 1-4 » in diameter; some of the

thicker ones have swollen cells at intervals (Fig. 8). The surface 
bears scattered orange granulations. The asci are globose, 9-10 #1 in 
diameter, and are borne on the hyphae in groups of about six; each 
ascus contains eight ascospores. The ascopores are globose or oval, 
tinged with yellow, 3.5-5 » in diameter (Fig. 9). (These dimensions 
agree well with those given for G. ruber by Saccardo (25): asci 
10-12 » in diameter, spores 4.5-5.5 #)- Asci have so far not been
