Comments 

 I Inocybe subtomentosa Peck. This belongs to a very confus- 

 ing series of species, especially as to their macroscopic characters, 

 including I. subdecurrens E. & E., I. caesariata Fr., 

 I. d u 1 c a m e r a A . & S.. I. u n i c o 1 o r Peck and I. 1 o r i 1 - 

 1 a r d i a n a Murrill. The\' all lack cystidia. The tomentose or fibril- 

 lose-tomentose covering of the pileus of these species is of a texture 

 easily aflfected by weather conditions, so that mature plants or her- 

 barium specimens of the same species can be referred to the Sections 

 Velutinae. Lacerae or Squarrosae according to the 

 weather conditions under which the plants developed. However, all 

 of the series mentioned are clearly separable from I. subtomen- 

 tosa and I. subdecurrens by the subrenif orm spores. The 

 type of I. subtomentosa approaches more nearly in its external 

 appearance I. caesariata. The spores, however, are of the vari- 

 able kind, ranging in the type specimens from 7-f) micr. in length with 

 a few up to 10 and 1 1 micr., by 5- 6 micr. wide, a few 7 micr. Here- 

 after such a condition will be referred to thus: 7-9 (lo.ii) x 5-6 (7). 

 Other collections show a larger per cent, up to 5 or 10 per cent of
