Fungous Flora of the Soil 475 



blunt, smooth, simple, septate, olive-brown, 300-350 by 4.5-5/1; spores 

 partly lemon-like, partly cymbiform, apiculate at both ends, at first pale 

 violet or steel-blue, finally dark violet or black, 10-12 by 6-6. 5ju; basidia 

 short, relatively thick, pale brown, either solitary or united in chaplets 

 for the support of the spores. 



Hab. Isolated from piece of birch found in the humous soil of the 

 woods called Spanderswoud near Bussum, Holland, May, 1901, 

 Koning. 



Sphaeronema Fagi Oud., Arch. Neerl. Sci. Nat. ser. 2, 7: 281. pi. g, 

 fig. I. 1902. 



Pycnidia spherical, loosely surrounded by dark hairs, black, opaque, 

 92-140/i in diameter, neck hollow, cylindrical, black, opaque, attenuate 

 upward, formed from very thin dark hyphse 500-540^1 high, base 23^1, 

 summit 7.6/i in diameter; glebula of conidia hyaline, elliptical, 3-4 by 2/x. 

 After the liberation of the spores there remain very slender penicillium- 

 like filaments at the summit of the neck. 



Hab. Isolated from the decaying leaves of Fagus sylvatica from the 

 humous soil of Spanderswoud near Bussum, Holland, May, 1901, Koning.

Colony orbicular, dense, snow-white, raised, 

 margin irregular, deeply crenate; mycelium 

 hyaline, submerged and aerial; submerged my- 

 celium consisting of yeast-like cells usually 

 swollen at both ends, constricted in the middle, 

 occasionally pyriform, guttulate; guttute through- 

 out the cell 7-15 by 2-8^1. Aerial hyphee 2 6-86 /x 

 long by 2-4^ thick, often irregular in diameter. Fig. 114. — Sachsia albicans

round, oval, or pyriform spores, similar to 



Mycoderma but distinguished from this genus in that short 



mycelial threads arise from the cells or spores. Size of these spores 



is 0.6-4 by 0.5-3^. The author further states that he had a culture 



which produced no spores and no such aggregations as described. Our 



culture so far has not been observed to produce the spores. The author
