 stumps, and so forth, in Germany, Poland, Italy, and France, in summer

 12-14/X thick; conidia produced in great numbers in the form of a spiral, 

 globose, often angled from lateral pressure, yellow-cinnamon brown. 



Hab. On decaying leaves and moist earth in Bohemia, Corda; near 



Pavia, Cavara; and in Belgium. See Lindau, 1. c, for authority that

 that appear as crutches; conidia small, globose, blackish. 



Hab. On moist soil in fir woods in Westphalia, Bonorden. 



Botrytis terrestris n. sp. 



Colonies at first white, later gray; sterile hyphae creeping, hyaline, 

 branched, septate, 1.5-3M in diameter; conidiophores erect, ascending, 

 septate, branched, 2-3. 5/1 in diameter, 50-200/x high; primary and second- 

 ary branches verticillate, dichotomous, or alternate; conidia produced 

 on the ends of the branches, forming more or less compact triangular 

 clusters that average 20-25//, obovate, somewhat angled, uniform 2.5-3 

 by 3-4M. hyaline to light gray. Clusters of conidia separate very easily. 



Hab. Isolated from potato soil on experimental plats at North Cohoc-
