On hard lima-bean agar, culture six days old; conidia from pseudo- 

 pionnotes : 

 Conidia: 0-septate, 82 per cent 



1-septate, 5 per cent 



2-septate, 2 per cent 



3-septate, 11 per cent, 28 x 4.1 (22-36 x 3.9^.7) m 



On the same medium as above, culture twelve days old; conidia also 

 from pseudopionnotes ; 

 Conidia: 0-septate, 15 per cent 

 1-septate, 8 per cent 



3-septate, 77 per cent, 33.5 x 4.1 (29-37 x 4-4.5) m; the smallest 

 21 X 3.4^:, the largest 40 x 4.5/i (both 3-septate) 



Chlamydospores all kinds except terminal, 0-septate dominant, measur- 

 ing 8.3 X 6.7 (6-10.5 x 5.2-8) m 



Average of the above measurements: 

 Conidia: 0-septate, 73 per cent, 7.2 x 2.7/i 

 1-septate, 5 per cent, 18x3.1yu 

 2-septate, 1.5 per cent, 24 x 3.2/x 

 3-septate, 20.5 per cent, 30.7 x 3.9yu 

 4-septate, rare, 45 x 4.2^4 



X. Section Discolor Wr., Phytopath. 3:31, fig. 1, g, h, j, 1913 



Conidia sickle-shaped, at the middle nearh^ cylindrical or broadened 

 toward the apex, somewhat abruptly apically attenuated, distinctly 

 pedicellate; mostly 3- to 5-septate, 5-septate dominant; microconidia 

 typically absent; chlamydospores intercalary only, usually scant; mycelium 

 typically well developed, with from nearly white to orange color as type. 

 Substratum from nearly colorless to chamois, pomegranate purple, and 

 spectrum red. Color of conidia very variable, mostly cinnamon to orange. 



Differs from sections Elegans and Martiella by absence of microconidia, 

 by the conidia being typically somewhat abruptly attenuate, by absence 

 of terminal chlamydospores, and by absence of vinaceous, drab-gray, 

 tawny-olive, and blue color of substratum. B}^ the shape of conidia 

 this S2ction occupies an intermediate position between sections Elegans 

 and Martiella; by its color it is closely related to sections Roseum and 

 Ferruginosum,
