 at first hidden by the whitish, fibril lose-subflocculose tomentum, 

 which in the central part soon disappears, thus revealing the 

 brownish colour. Stem somewhat wavy, thin (2— 3 mm), 3— 4 cm 

 high, inside and outside pallid incarnate-brownish, at first every- 

 where white-plum ulose-iibrillose. 



11. I. flocculosa (sensu Mass.).

C a p 2— 3 x / 2 cm, campanulate-convex, then expanded gibbous, 

 of a dull brown colour, at last somewhat lighter (subfulvous», 

 everywhere fibrillose tomentose-subsquamulose; towards the edge 

 the fibrils are somewhat hoary-gray and at last slightly rimose. 

 Veil well developed, fibrillose. Stem about 5 mm broad. For 

 the rest not much different from no. 10. Vide also no. 21.

Fig. specim.: Hollufgaard, wood of Quercus and Corylus, on 

 moist ground, Sept. 1916. 



Corresponds exactly to the description given by Karsten. (Kri- 

 tisk öfversigt af Finlands Basidsvampar, p. 465.) The apex of 

 the stem is very slightly white-flocculose. Well characterized by 

 the brown, subrimose cap and lilac apex of stem. Affined to 

 /. descissa. 



13 a. I. geophylla (Sow.). 



Spores obliquely ovate-ellipsoid or ovate, 8—9 x 4-6u. Cystidia 

 dispersed, fusoid-bottleshaped, rather long, apex muriculate. Apex 

 of stem clad with hyphæ and cystidia af the same shape as 

 those on edge of gills (1916).

 mon in similar localities. 



13 b. I. g. var. alba (= A. albas Sehw.). 

 Spores and Cystidia like no. 13 a. - The white — when old 

 somewhat palfid — cap apparently is the only characteristic 

 distinguishing this form from the lilac one It is common
