The original gives the conidial head as being only 8^n in diameter. It is not uncommon to find it measuring 130/X in diameter. Also, the conidiophores measure as high as 400/1. The original gives the mycelium as continuous, while it is sparsely septa

Reverse of colony yellow-green. Conidiophores mostly arising separately, 100- 250^1 high by 3-5M thick, with 1-3 alternate diverging branches bearing once or twice verticillate branchlets. Conidiiferous cells 7-10 by 2-3^1, usually in verticils; conidia globose, in diameter. Colonies liquefy gelatin with alkaline reaction to litmus, and in gelatin and on potato plugs a lemon-yellow color. Hab. Isolated from soil of oat field, Cornell University, Ithaca, N.
