Genera of Lower Basidiomycetes not Before Reported from North 

 America. W. C. Coker. 



Reports the occurrence in Chapel Hill of three Genera; all grow- 

 ing on wood as saprophytes, and forming small pustules or expanded, 

 resupinate layers. They are as follows: 



Saccohlastia Moller. A remarkable genus with elongated basidia 

 divided across into four cells as in the rusts ; and arising in a peculiar 

 way from the tip of a pendant pear-shaped sac. Three species have 

 been reported, two from South Brazil and one from Poland. Our 

 plant is considered a variety of S. ovispora Moller from South Brazil. 



Platygloea Schroeter. Two species were found on Crepe Myrtle, 

 both of which seem new. About nine others have been described from 

 Europe and the tropics. Our plants seem nearest Helicogloea Lager- 

 heiini Pat. which is usually considered as not generically distinct from 

 Platygloea. Our species have small, crowded basidia borne in corymbs 

 and two-celled bj' a cross partition. 



Sirohasidium Moller. In this genus the basidia are borne in chains 

 and are divided into two cells by an oblique wall or into four cells 

 by longitudinal walls. Three species have been described, all fi-om 

 South America (one from Brazil, two from Equador). Our plant 

 agrees well with the one from Brazil, S. Brefeldia)ui))i Moller. 



Attention was also called to the Genus Septobasidiioii, which is well 

 represented in America, but in which the basidia have been misunder- 

 stood.

The Life History of a Gall-Making Psyllid {Pachypsylla mamma 

 Riley). Lantern. Dr. B. W. Wells. 

 Oviposition on under side of young hackberry leaf. Nymph mi- 

 grates to upper side of leaf where galls are initiated near the principal 

 veins. Nymph grows very slowly at first while gall on the other 

 hand grows very rapidly. Usualh' but one insertion of the mouth- 

 parts into the leaf tissue is made, the insect keeping its position for 

 an extended period. The nymph escapes from the gall in the fall, the 

 adults appearing immediately afterward. These overwinter in bark 

 crevices or ground debris.
