Rather variable. Fig. 1 represents the comparatively slender 

 and light-coloured form which is occasionally mistaken for R. 

 (Nolanea) pascims, from which it is easily distinguished by the 

 subspheric, obtusely angular spores and the »mealy« odour. 



17. R. costatus Fr. var. 



Spores 7 — 8 x 6V2 — 7 (a, subspheric-pentangular. 



Fig. specimens: Hjallese, permanent pasture-field, Nov. 1899 

 (and 1914), subfasciculate. 



Not very well distinguished from dark forms of no: 16. My 

 plant had a (very faint) mealy smell. The stem was not white- 

 squamulose above as indicated by Fries. By its pitch-brown 

 colour and the rather small spores it formed a transition to Ent. 

 Cordæ Karst. 



18. R. Batschianus Fr. 



Spores 6 l / 2 — 7 1 /, X 6— 6 l / 2 u(or 6 1 /, x 5 3 / 4 ) almost spheric, slightly 

 angular. Cystidia absent. Basidia 4-spored. Sporedust very 

 pale incarnate. 



Fig. specimens: Kirkeby, wood of Picea, on mossy ground, 

 Oct. 1914. Also found in Håre Bjerge, Oct. 1906 and 14, and at 

 Hesbjerg, Oct. 1912 in similar localities. 



This species differs very much from all other Entolomas which 

 I know. It has the slightly viscid cap of the Genaini, but it is 

 somewhat hygrophanous. The almost sootbrown, small cap 

 (which is minutely striate at the margin) and the long and slender 

 stem reminds one of Nolanea, the at length somewhat depressed 

 cap and the at last sligtly descending gills recall Eccilia — My 

 plant belongs to the second type of Fries (with whitish gills). 



II. LEPTONIA. 



1. R. euchrous (Pers.) 



Spores 9 — 11 x 5 — l l j» u, oval or ovate, obtusely angular-wavy. 



Fig. specimens: Hjallese, 1) solitary on stump of Corylus, 

 Sept 1897; 2) gregarious on stump of Alnus, Oct. 1899. —'Not 

 uncommon. 



When examined by means of a pocket-lens the stem is seen 

 to be dusky with minute violet fibrils. 



2. R. serrulatus (Pers.) 



Spores 8—11 x 6— 7 |u, ovate-oval, with 5 — 8 rather sharp angles. 

 Basidia 4-spored (in B.). Cystidia clavate, 11 — 12 u broad, fasci- 

 culate, pale gray (1909).
