<i>Ascosphaera osmophila</i> Sp. Nov., An Australian Spore Cyst Fungus

Abstract

Ascosphaera osmophila sp. nov. is described. Septa occur often close together and remain intact when the mycelium disintegrates. A fairly good production of mature spore cysts occurs only on media containing 10% sugar or more. A. osmophila lives in association with the mason bee, Chalicodoma mystaceana, and with leafcutter bees, Megachile spp., in Queensland.
