A series of successive developmental stages of long basidia situated 

 about 6 mm. from the rim of a single pileus is shown in Fig. 91,

Fig. 91. — Coprinus sterquilinus. Stages in the development 

 of along basidium ; a at 8 p.m. ; 6 at 9 p.m. ; c at 10p.m. ; 

 rfat 11 P.M. ; e at 1 2 midnight ;/ at 2 a.m. ; g at 2. 30 a.m. ; 

 h at 3 A.M.; i at 8-11 a.m.; j at 7 p.m., spores 

 turning brown ; i at 12 midnight to 6 a.m., spores 

 black ; I about 6 a.m., two spores have been discharged 

 and a third with a water-drop at its base is about to be 

 discharged; 7n at 6.10 a.m. ; n at about 6.40 a.m., 

 undergoing autodigestion ; o at about 7 a.m. just before 

 entire destruction. All the stages from a to o were 

 passed througli in thirty-six hours. Magnification, 408. 



Stage a was sketched at 8 p.m., stage 6 at 9 p.m., and stage c at 10 p.m. 

 The development of the sterigmata therefore took about two hours. 

 Stage d was sketched at 11 p.m., stage e at 12 midnight, stage/
