Abstract
Two new species, A. aggregata and A. fimicola, are described. A. aggregata is probably pathogenic in the leaf-cutting bees, Megachile pacifica and M. centuncularis, and in the mason bee, Osmia rufa. In all 3 spp. it causes a swelling of the larval body due to development of the spore cysts beneath the larval integument that easily bursts giving the dead larvae a ragged appearance. A. fimicola is primarily a saprophyte growing on the fecal pellets of O. rufa. The conidial state of Bettsia alvei is proposed transferred to Chrysosporium farinaecola comb. nov. (Ovularia farinaecola Skou).
