Abstract

The Aspergilli are divided by The AspergiUua flavipe8 group consists of a single species, A. flavipe8 (Bainier & Sartory) Thom & Church. The closely related A. terreu8 group includes three species, of which the commonest and most important is A. terreu8 Thom and its three varieties, boedijni (Bloch.) n.var., flocco8ua Shih and aureus n.var. It is interesting to note that old cultures of A. flavipes often resemble A. terreu8, the two species being readily distinguished, however, when young cultures are ex-
