the herbarium, sends up vertical hyphae, which swell up at 

 the top, and bear a large number of small protuberances or 

 branches, the sterigmata (A, c, st, Fig. 191). Each sterigma 

 produces gradually a long chain of conidia, so that each

vertical hypha is terminated by a round mass, made up of 

 these radiating strings of conidia. The sexual organs appear 

 a little later than the conidia. The end of a branch of the 

 mycelium becomes coiled into a hollow spiral (A, as, Fig.
