32 X 10-12 mic. Dr. Rehm, (Krypt. Fl. 1:1193. 

 1896) describes G. gigas as follows: "Sporen 

 breit spindel-formig, einzelig mit einen grossen, 

 centralen iind jc einem kleinen Oeltropfen 

 in den Ecken, dann an jcdcn Ende mit einem 

 warzenformigen Anlangsel, farblos, 30-40 mic. 

 lang., 12-14 riiic. breit" (p. 11 74. f. 5). 



Schroeder's and Massee's descriptions agree 

 with Rehm's. 



Although tlie Colorado material agrees in 

 all respects with that identified by Phillips as 

 G. gigd-'^, (Journ. Bot. 31:129. 1893), it does 

 not seem to l)e identical with Kromholz' plant, 

 Helvella gigas (G. gigas), differing in color, 

 size, and size of spores. Also, his specimens 

 were collected in April and May, while the 

 Colorado form occurred in August. Likewise, 

 the habitat is different, the one growing upon 

 wood, the other upon the ground. 



Therefore, I agree with ]Massee in his inter- 

 pretation (Fl. 4:478. 1895), considering that 

 this specimen is identical with that of Phillips. 

 "I consider the plant noted by Phillips as a 

 previously undescribed species remarkable for 

 tis great size as also for its very small spores."
