CHEILOSCYPHUS, Corda. A genus 

 of Jungermanniese (Hepaticacece), founded 

 upon Jungermannia polyanthus, L., which is 

 not unfrequent in wet places.

 PUS. 



CHEIROSPORA, Fries. A genus of 

 Melanconiei (Coniomycetous Fungi), grow- 

 ing upon the twigs of the beech. The myce- 

 lium spreads under the epidermis, and bursts 

 through in rounded or irregular, conical, 

 black pustules, 1-20" in diameter, which are 

 composed of a large number of fine filaments, 

 unequal in length and waved, each termina- 

 ting in a bunch of spores. The heads are 

 formed of chains of spores like a Penicillium, 

 when young, but crowded together more 

 densely as they become more fully developed 

 into a globular or oval head, about 1-700"; 

 the spores about 1-4000". This genus cor- 

 responds to Stilbospora, Montague, Myrio- 

 cephalum. De Notaris, and, apparently, Hy- 

 peromyxa, Corda, but the latter is said to 

 have a mucous vesicle enclosing the head.
