 Microconidia on aerial mycelium typically present, from oval to oblong, 

 mostly 0-septate; macroconidia mostly 3-septate, of nearly even diameter 

 throughout or but slightly broader either toward apex or toward base, 

 nearly straight in lower half and more or less curved near apex, with 

 somewhat rounded apex or only slightly pointed or constricted, typically 

 from slightly pedicellate to apedicellate; aerial mycelium mostly from 

 white to a light tint of chamois and drab hues; substratum,^ on neutral 

 agars, never rose-pink nor pomegranate purple in color, sometimes 

 from vinaceous to blue; color of conidia, except in acid media, mostly from 

 pale buff to drab, often distinctly from green to blue.
