“Vegetative mycelium consisting of fine, septate branching, 
colorless hyphae growing on and in the substratum. Fertile 
hyphae abruptly differentiated, erect, stout, swelling distally to 
form a well-distinguished terminal head, the whole surface of 
which gives rise to sporophores several times subumbellately 
branched, the ultimate branchlets adjoining successively continu¬ 
ous hyaline spores. The fertile hypha corticated by sterile hyphae 
which grow upward with it, eventually forming a special en¬ 
velope about the sporiferous portion of the head.”
