Fig. specimens: Hjallese, wood of Fagus, Oct. 1904. — Not 

 common, generally solitary, in moist woods. 



The form cuspidata figured by Fries (Icon, sei.) with an acute, 

 very prominent umbo I have never met. My plants are convex 

 or somewhat campanulate, obsoletely umbonate. It is a very 

 distinct species on account of its almost spheric spores, its sub- 

 fuscous, very coarsely striate cap and the broad, dusky gills. 



12. R. coelestinus Fr. 



Spores 8 — 9 x 7 ja, obtusety 5-(6-)angular, spheric-ovate. Basidia 

 4-spored. 



Fig. specimens: Tommerup, pasture on ground sloping towards 

 bog, outside a wood, Nov. 1907. 



My specimens differ from the description of Fries in not having 

 the centre »scabrello« and the stem at first not fistulöse By 

 the subspheric spores it can easily be distinguished from the 

 bluish Leptonias. The cap is bluish-fuscous or dingy steelblue 

 (when dry: dark steelgray and silky). 



IV. EGCILIA. 



A. OVISPORÆ. 



1. R. carneo-albus Wither. (Clitopilus c.J 



Spores 8 — 11 (generally 10—11) ja long, subovate, irregularly and 

 obtusely angular. 



Fig. specimens: Korsør, on hedgerow in wood of Fagus, Sept. 

 1902. — Also at Rold (Jylland), Hesbjerg (Fyn) etc., always in 

 woods. A dwarfy form, cap only 3 mm broad, is also met 

 with. 



It is extremely close to R. sericellus and hardly deserves spe- 

 cific rank. The only differences are the somewhat decurrent gills 

 and the slender stem. Occasionally the cap is almost snow- 

 white. Altogether it might be characterized as an etiolated, sil- 

 van form of R. sericellus. 



2. R. cancrinus Fr. (Clitopilus c.) 



Spores 10 — 13 x 7 — 7V 2 M, ovate or oval, irregularly wavy. Ba- 

 sidia 4-spored. 



Fig. specimens: Kerteminde, sandy pasture near the coast, 

 Julv 1909. — Also at Sanderum, pasture on boggv ground, Aug 

 1909. 



Differing from no: 1 chiefly in the depressed, subinfundibuli 

 form cap, shorter stem and strongly decurrent gills.
