The Bureaux de le "Revue de Viticulture," Paris, issues a 

 17-page illustrated account of the new fungus — "Sur le Stearo- 

 phora radicicola, champignon des Racines de la Vigne" — which 

 the authors detected in the living tissues and of which they say: 

 "nous avions d'abord songe a rattacher cette espe nouvelle au 

 groupe, d'ailleurs mal nomme, des Endoconidium ; les donnees 

 vague et insuffisantes, pubhees sur la genese des spores dans ce 

 genre, ne nous ont pas permis de confirmer cette assimilation, et 

 nous esperons pouvoir etablir, dans un travail ulterieur, que le 

 Stearophora constitue un groupe special representant vraisembla- 

 blement un type primitif d'Ascomycetes a asques dissocies."

In Bulletin 70, Experiment Station, State of Washington, we 

 find an account of the "Powdery Mildews of Washington," the 

 Erysiphaceae. Following the general account is a key to the 

 genera, then the genera and species are fully described, the ap- 

 pendages and spores illustrated by one full-page plate.

This is a very interesting study, "The Rate of Growth of 

 Panaeolus Retirugis," Contribution No. 113 from the Department 

 of Botany of Cornell University. Measurements were taken 

 morning and evening during the latter part of March and early 

 April — complete records obtained for 18 plants, the rate of 

 growth then worked out in curves. The stem grows slowly at 

 ifirst, then very rapidly 40 to 56 hours, for about 24 hours slowly 

 again until it ceases. Growth is more rapid by night than by day.
