f“There exists no original specimen of this species in Fries’ herbarium. According to 
his diagnosis and certainly according to specimens of several authors, it is a variety of fomen¬ 
tarius. However, Fries’ illustration (Ic. t. 184 f. 2) is an exact picture of the stratified form 
of roseus.”—Bresadola.
