46 THE WEST VIRGINIA FLORA 



On some of the insects there is a cottony or flocculent 

 mass of white mycelium interwoven in a somewhat reticulate 

 manner, and collected in strings or bundles. It bears no 

 fruit, but is probably a luxuriant growth of the mycelium 

 of this fungus. 



Occasionally the fungus seems to spread from the insect 

 to bark immediately adjacent to it. 

 C. FLAGELLARIS E. & E. Field Mus. Bot, i :ioo (1896). 



TYPE HABITAT : On dead stem of Helianthus decapetalus, 

 Dec. 3. 1894 (NuttalL discov. 1762, 650). 



(C. lactea S. & E. partly, Sacc. No. 3550.) 



Sporodochia gregarious, subglobose, subhyaline and gela- 

 tinous when fresh, lens-shaped, with a thin spreading mar- 

 gin, orbicular, .33 to .50 mm diameter, yellowish-amber color 

 (whitish in the center) when dry. Sporophores densely 

 fasciculate, flagelliform 2 to 3 times dichotomously branched, 

 80 to 100 fi long, separating into the short cylindrical, hya- 

 line, 4 to 5 x i /A conidia. 



This was included by Saccardo in Michelia II, p. 581, in 

 Cylindrocolla lactea, S. & E. (on rotten wood of Kahnia), 

 but differs in the shape and color of the sporodochia and the 

 sporophores only 2 to 3 times dichotomously branch. C. 

 lactea retains its white color when dry, and resembles young 

 Lasiosphaeria ovina.
