Fungous Flora of the Soil 479 



In a solution of requisite ash salts plus 0.5 per cent ammonium tartrate 

 and 10 per cent cane sugar, test was made for inversion, of the sugar. 

 Inversion took place. The yeast cells forming the membrane in this 

 solution were round, 6-8 m in diameter. Sediment consisted of difEerent- 

 length hyphal forms. (Description after Adametz.)

Colonies cushion-like, somewhat powdery, white; hyphse creeping, 

 sparsely septate; conidiophores erect, short; conidia in chains, short 

 cylindrical, truncate at both ends, 5-1 o/x long, 4fj. broad, hyahne. 



Hab. On barren soil, on bones and decaying paper, Germany, Lower 

 Austria, Italy, and France, in summer and autumn. See Lindau, 1. c, for 

 statement that fungus grows on barren soil.

Colonies orbicular, dense, floccose, at first white, later very light rose- 

 colored; vegetative hyph^ hyahne, sparsely septate, branched, very thin 

 (2.5-3JU thick); conidiophores erect, simple, arising as side branches from 

 vegetative hyphs, unseptate, 40-60 by 3/x; conidia numerous, elliptical or 

 oblong, straight or curved, nearly hyaline, 4 by 1-1.5/x, borne singly at 

 the apex of the conidiophore, but pressed to the side by the next pro- 

 duced and adhering by means of slime, eventually resulting in a capitule, 

 1 4-1 6 /x in diameter and of very dilute rose-color. 



Hab. Isolated from humous soil, Holland, Koning.

 pi. 16, fig. I. 1902. Lindau, Rab. Krypt. Flora Abt. 8, 1 : 108. 1907. 



Colonies orbicular, floccose, at first white, later with white margin and 

 dilute rose-colored center; sterile hyphas branched, septate, hyaline, 3-5/i 

 thick, intermixed with thicker, irregular segments of septate hyphas whose 

 cells appear very much as chlamydospores ; conidiophores erect, thin, 

 100-200/X high, unbranched, nonseptate, at the tip with a globose, 20-2 6/i- 

 in-diameter capitule of a very dilute rose-color; conidia conglutinate, 

 globose, 2.3-2.s/i in diameter, almost hyaline. 



Hab. Isolated from pulverized humous soil from the woods called 

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