FIG. 98. Panaeolus campanulatus. Analysis of the hymenium. A, cross-section 

 through the hymenium h and the subhyrnenium s (same as area B in Fig. 96). 

 The subhymenium has been softened so as to make the hymenium more distinct. 

 The four past-generation basidia, a, are set out at B ; the five present-generation 

 basidia, b, are set out at C ; the three coming-generation basidia, c, are set 

 out at D ; the twelve future-generation basidia, d, are set out at E ; and the 

 twelve paraphyses, e, are set out at F. The present-generation basidium 

 farthest to right in A and C, has just discharged two of its spores and is about 

 to discharge a third spore. That the moment of discharge for this third spore 

 has arrived, is indicated by the drop of water, now of full size, which has been 

 excreted within the last ten seconds from the spore hilum. Magnification, 718.
