Fungous Flora of the Soil 477 



Oospora lactis (Fres.) Sacc, Syll. Fung. 4:15. For synonymy and 

 bibliography see Sacc. Syll. Fung. 20: 233. 1911. (Compare Lindau, 

 Rab. Krypt. Flora Abt. 8, i: 32. 1904-1907.) 



Colonies far-spreading, membranaceous, velvety, pure white, often 

 becoming a thick covering over substratum; hyphas simple or branched, 

 creeping or somewhat ascending, hyaline, of variable length and breadth, 

 mostly 6-1 2/x broad, breaking up into irregular pieces that are to be 

 considered as spores; spores cylindrical to ovate, often also globose, or 

 somewhat irregular in form, mostly 6-2 om long. 



Hab. Isolated from garden soil, Copenhagen, Hansen; Germany, 

 Adametz.

 figs. 1-4. 1902. Lindau, Rab. Krypt. Flora Abt. 8, i: 60. 1904-1907. 



Colonies orbicular, dense, at first nearly hyaline, later entirely green; 

 sterile hyphse creeping, when young hyahne, consisting of alternating 

 longer and shorter cells with granular protoplasm, when old green, con- 

 sisting of cylindrical cells of equal length with homogenous protoplasm; 

 conidiophores ascending or erect, yellow or green, closely septate, divided 

 into cylindrical articulate cells that readily separate from each other, 

 branched; branches alternate or nearly opposite, once or twice dichoto- 

 mously divided; conidia in short chains, immature subglobose, mature 

 ellipsoidal, both ends apiculate, greenish, 4-10 by 2-5/1. 



Hab. Isolated on gelatin from pulverized humous soil from woods 

 called Spanderswoud near Bussum, Holland, March, 1901, Koning.

 1894. Lindau, Rab. Krypt. Flora Abt. 8, i: 55. 1904-1907. 



Colonies far-spreading, powdery, white, occasionally with reddish 

 glimmer, becoming gray with age ; hyphag hyaline, septate, little branched, 

 2-5/x thick; conidiophore branches 4-5 together, arising from the hyphas 

 in widely separated groups, irregularly branched, 50-1 00/x long, sparsely 

 septate, last branches of conidiophores which carry the conidial chains 

 almost constantly about 2$ix long, at the tip somewhat attenuated and 

 breaking up into conidial chains; conidia ellipsoidal, both ends somewhat 

 flattened at first, later rounded, hyaline, 6.5-8/1 long and 4.5-5.3/1 broad. 



Hab. On mushroom beds, manure, straw, soil, and the like, in Paris. 

 (Lindau, 1. c. ) No mention is made as to who found it on soil. 



Monilia geophila Oud., Arch. Neerl. Sci. Nat. ser. 2, 7: 286. pi. 19, 

 fig. I. 1902. Lindau, Rab. Krypt. Flora Abt. 8, i: 56. 1904- 1907. 



Colonies composed of loosely intertwined hyphas, yellowish white or 

 ocher-yellow (Sacc. Chromot. 28 and 29); vegetative hyphas creeping, 

 branched, sparsely septate, fertile hyphae ascending or erect, closely 

 septate, toward the top either once or twice forked or irregularly branched;
