I was unable to identify it with any known species. Therefore, 



Fig. 5. — Coprinus curtus. The same pure culture as in Figs. 3 and 4, about 

 3 hours after the stage shown in Fig. 3 and about 2 hours after the stage 

 shown in Fig. 4. Probably photographed about noon. The fruit-bodies 

 in a group on the left are still shedding spores, while those in a group in 

 the centre, which have revolute pilei, have entirely discharged their spores 

 and are now exhausted. To the right and left of the bases of the stipes of 

 the median fruit-body group, as well as in the front of the cultuie, are a 

 few rudimentary fruit-bodies which, after 24 hours, will resemble the 

 mature fruit-bodies already described. Photographed at Cornell University 

 by the late G. F. Atkinson, to whom the author sent the culture. Natural size. 



for convenience in reference when describing the reactions of its 

 fruit-bodies to external stimuli in Volume I of these Researches,
