 section 200 [x thick, not colored, composed of loosely interwoven, 

 thick-walled hyphae 3 [x in diameter, nodose-septate, not in-

C. Litschaueri has the aspect of C. stramineum and occurs on a 

 frequent substratum of the latter but the spores of C. Litschaueri 

 are the larger and the hyphae are thicker-walled than those of 

 C. stramineum, and more like those of P. cremea.
