ACEOSTALAGMUS CLONOSTACHYS. 331 



Resembling Vcrticillium in habit, distinguished by tho 

 cluster of spores involved in mucus at the tip of each 

 branchlet. By some the spores are considered as being 

 enclosed in a cell, as in Mucor, but it has been shown by 

 Berlese that the apparent membrane consists of mucus that 

 disappears at maturity.

Tufts pulverulent, effused, orange-red or vermilion ; vege-

Sterile hyphae creeping, continuous ; fertile, erect, simple, 

 continuous below, septate towards the apex and giving off 

 whorls of branches, iisually in fours, from the septa; 

 branchlets also bearing whorls of branchlets, usually in 

 fours; branchlets subulate, the upper part densely covered
