(1) ripe or almost rij^e spores, like those at a and b ; (2) spores which 

 have just attained full size or are almost of full size, like those at c, 

 d, g, and h ; (3) very young spores of the size of those at/, or some- 

 what larger ; and (4) spores just beginning to form on the ends of 



Fig. 42. — Bussulaochroleuca. Surface view of the hymenium 

 showing the spores, on the first day of the spore- 

 discharge period. The drawing was made with the 

 camera lucida, but the roughnesses on the walls of the 

 almost ripe spores were added diagrammatically. 

 a and b, two of the oldest basidia with ripe or almost 

 ripe spores ; c, four spores which have almost attained 

 full size but which still have smooth walls ; d, half- 

 grown spores ; e, spores which are just beginning to 

 form on the ends of their sterigmata ; /, g, and h, 

 abnormal trisporous basidia. Magnification, 330. 



the sterigmata, like those at e. If one considers the position of the 

 basidia bearing spores of any one age, one at once perceives that the 

 individual basidia are well isolated from one another. 



Amanita rubescens. — This well-known Amanita (Vol. II, Figs. 

 135, 136, pp. 378, 379) clearly belongs to the Armillaria Sub-type 

 of fruit-body. A glance at the surface view of the hymenium, 

 illustrated in Fig. 43, A and B, shows that the basidia which bear 

 spores of about the same age are widely separated from one another.
