EREMASCACEAE IMPERFECTAE 217 



elongates, septum foiination proceeds rapidly until the resulting cells, even- 

 tually arthrospores, are uninucleate. In this process often the protoplasmic 

 contents of certain cells disappear, perhaps aiding in the disintegration of 

 the chains of arthrospores. Chlamydospores large and thick-walled spores 

 are multinucleate. On certain media some blastospores are produced having 

 1-3-nuelei, often uninucleate. The so-called conidia of this species seem to 

 be cells densely filled with a granular protoplasm and no trace of a nucleus. 

 Obviously they are not conidia in the sense in which this term is usually used 

 in other groups of fungi. 



The genus is quite large, the species being mostly saprophytic on earth 

 and decaying organic matter. Twelve have been reported on man, eight from 

 infections of the respiratory tract, three from stools (parasitism unknown) 

 and two from blastomycosis. O. hostonense differs in some respects from the 

 other members of the genus and perhaps should be placed in a separate genus.
