Forming scattered, indistinct white patches, primary 

 branches 3-4, alternate, secondary branches attenuated at 

 the tip, in whorls, a whorl also terminates the main stem,

 t. 7, f. 16; Sacc., Syll., iv. n. 784. 



On herbaceous stems. 



An examination of the type specimen in Berkeley's 

 herbarium at Kew shows that the conidia are distinctly 

 uniseptate at maturity, hence technically the species is not 

 a Verticillium; but as the agreement with this genus is 

 perfect in every other respect, it is retained here. 



Verticillium terrestre. Sacc. 



Vegetative mycelium creeping, interwoven, white, fertile 

 erect, septate, often wavy, sometimes branched once or twice
