BETTS : THE FUNGI OF THE BEE-HIVE. 161 
SUMMARY. 
e . : . 
1. An account is given of the previous work that has been done on the 
fungi present in bee-hives; and some questions arising from these 
records are discussed. 
2. A general description of the conditions prevailing in the hive, and of the 
distribution of fungous growth in it, are given. 
3. The following twelve fungi are described :— 
Probably confined to the hive: 
Pevicystis alvet, Oospora favovum. 
Adapted to hive-life, but not confined to this habitat: 
Gymnoascus setosus; Evemascus fertilis (perhaps). 
Common, but not specially adapted to life in the hive: 
Penicillium crustaceum, Aspergillus glaucus, Citvomyces subtilis, C. 
. glaber, Mucor evectus. 
Occasionally present : 
Aspergillus nidulans, Sovdaria fimicola, Gymmnoascus vuber.
