On all sorts of decaying substances. Common. 



[United States.] 



One of the commonest of Fun^, and very variable. Numerons species 

 have been characterized, but it is questionable ^vhether many of them should 

 not be united under this, which scarcely claims a place as a distinct species, 

 since Tulasne has indicated its affinity with Sphceria herharum, of which he 

 regards it as a conidiophorus condition, as well as Macrosporium sarcimdUf 

 Berk, and probably Macrosporium cheirantki Fr. (Fig. 256.)

Cladosporium." 



Flocci erect, at length declining, fasciculate, sub-olivaceous,
