This species is very closely related to /. fastigiata, forming a 

 transition from I. fastigiata to /. mimica Massee (which has larger 

 spores). — Ag. Curreyi Berk., which Massee refers to I. fastigiata, 

 seems to be intermediate between the typical I. fastigiata and 

 I. squamata (to judge from Cooke's figure (1. c. tab. 398). 



29. I. fastigiata (Schæff.) 



Spores oval-subphaseoliform, 10—11 X h 1 ^ u, Gystidia cylindric, 

 obtuse, about 12 u broad. 



Fig. specim. : Hjallese, in wood of Fagus and Corylus, July 1905. 

 Not uncommon. 



The cap in this species varies more or less acute, the stem is 

 iibrillose-subfloccose, (not pruinose). Like most modern authors 

 1 use the name I. fastigiata for this smooth-spored species, excluding 

 diverse rough-spored ones. — /. flavella Karst, as far as I can 

 see only differs in larger spores. Bresadola's figure is somewhat 

 exaggerated, very acute with almost green gills. — /. fastigiata 

 xarsuperba Fries (Icon. sei. tab. 108) hardly belongs here. 



30. I. perlata Cooke. 



Spores ovate, somewhat oblique, 9V 2 — lO 1 /, x 6 1 /« H- Cystidia 

 cylindric-clubshaped, 11 (a broad. 



Fig. specim.: Tommerup, old grassfield behind copsewood, 

 gregarious, July 1914. 



Cap 5—672 cm > somewhat conical, at last expanded and 

 subumbonate (when moist subviscid), even, very minutely fibrillose, 

 umbo fuscous-brownish, whitish towards the edge, later on be- 

 coming fibrillose-subrimose, the fibrils darker. Stem about 8 cm 

 x 10 — 12 mm, at first white, somewhat fibrillose (not mealy), then 

 turning brownish inside and outside (from base upward). — My 

 plant is not quite so large as Cooke's figure. 



31. I. brunnea Quel. 



Spores 9—11 X 5— 5V 3 u - Cystidia on edge of gills inflated club- 

 shaped, 12 — 1 5 ju broad. 



Fig. specim.: Hjallese, behind a hedge, Sept. 1902. — Rather 

 common in light foliaceous woods, often gregarious. 



The more or less bright chestnut-brown colour of the cap 

 distinguishes this species from its allies. The bulbless stem is 

 originally almost white but soon becomes partly flushed with 

 brown. 



When in bud the central part of the cap is often partly 

 covered by whitish adpressed scales and fibrils which soon 

 disappear. When this rudimentary universal veil is very apparent 

 we have, I believe, /. maculata Boud.
