Cephalosporium Koningi Oud., Arch. Neerl. Sci. Nat. ser. 2, 7: 285. pi. 

 ly, fig. I. 1902. Lindau, Rab. Krypt. Flora Abt. 8, i: 108. 1904-1907. 

 Colonies white; sterile hyphae creeping, branched, hyaline, nonseptate, 

 with intercalary globose or fusiform chlamydospores ; chlamydospores 

 with foamy protoplasm, 12-15 by 6-12.5^1; conidiophores erect, con- 

 tinuous, with smoky protoplasm, simple or branched, terminating singly 

 with a globose, 2 5-35M-in-diameter glomerule of conidia that adhere 

 closely and are destitute of a membrane; conidia globose, hyaline, con- 

 tinuous, 5-1 o/i in diameter. 



Hab. Isolated on gelatin from humous soil from woods called Span- 

 derswoud near Bussum, Holland, April, 1901, Koning. 



Lindau, cited above, is of the opinion that this species belongs with the 

 Mucoraceae on the grounds of the presence of chlamydospores, the lack of 

 septa, and the loose coherence of the spores in the glomerule.

Colonies orbicular, fioccose, at first white, 

 later dotted or spotted with green, finally 

 verdigris or light olive-green; vegetative 

 hyphae hyaline, very sparsely septate, 

 branched; branches alternate or opposite, 

 each I- or 2- or 3-forked, ultimate branches 

 carrying the S-io/z-in-diameter conidial 

 head; conidia almost hyaline, ellipsoidal, 

 3-4/1 long by 2.5-3A1 wide, destitute of 

 mucus, soon separating.
