Stysanus microsporus Sacc. Mich. I. p. 274 (1878). 



Gregarious, grey then brown. Stem thread-like, formed 

 of brown almost continuous hypiice, the head clavate ; conidia 

 in chains almost globose, hyaline (purplish-brown in the 

 mass), 2-4/.t long, 2-2.5/^ thick. On decaying wood, or 

 herbaceous stems, &c. 



Collected by W. N. C'heesman on decaying wood at Selb\', 

 Yorkshire, Sept., 191 7. 



There is in the specimen a rich production of conidia, so 

 that the heads (in the protected specimen) had become over- 

 weighted, split up and fallen apart in tripartite lobes. The 

 stems are very slender and black, the heads a delicate 

 purplish brown.
