Il has a faint mealy smell. My plant corresponds to the um- 

 bonate form figured by Fries (Icon. sei. tab. 69 3 ). His other 

 form (69 4 ) seems to me rather divergent. 



21. C. murina (Balsch) var. 



Spores Q 1 j 2 —8 X 4 — 5 u. 



Fig. specimens: Aarup, mixed coniferous-foliaceous wood, Oct. 

 1896. This species is met with occasionally especially in 



foliaceous woods, somewhat gregarious. It has a very slight 

 mealy smell. — My plant differs from the Friesian description 

 by not becoming umbilicate. 



22. C. clusilis Schroet. (Fr.?). 



Spores ovate, 6 — 7 X 4 1 /-, u. Basidia 4-spored. Cystidia 0. 



Fig. specim.: »Sortsø«, in wood at Gerup near Holstenshus, 

 on Sphagnum, July 1910. — Also found (on Sphagnum) in other 

 localities of the some district, July — Aug. 1914. 



This little Collybia, which reminds one of an Omphalia, is 

 very well described by Schroeter (loc. cil.). C obstcms Britz, 

 appears to be identical. It has a very faint somewhat mealy 

 smell. 



C. clusilis seems to be very differently conceived by the leading 

 mycologists. Probably the form B , mentioned by Fhies as 

 growing »in pratis post largas pluvias, inter Hypna , is my plant, 

 although his description does not fit very well. The plant 

 described by Quélet (Flore mycol.) as growing in woods and 

 on sandy heaths can hardly be identical. Cooke's figure is not 

 like ray plant, and »C. clusilis of Karsten has larger spores 

 (7—9 x 5-6 u). 



23. C. miser Fr. var. 



Spores ellipsoid, 7 1 / 2 3 1 ., u, Cystidia 0. 



Fig. specim.: Stenløse, on the ground in shady wood ofCorvlus 

 and Fagus, Sept. 1905 (and 1916). 



My plant agrees fairly well with the figure (Icon. sei. 70 4 j and 

 description of Fries, but grows in foliaceous woods, and the gills 

 are not exactly »cinereæ« but rather pallid-sordid. The apex of 

 the stem is slightly pruinose. Karsten (loc. cit. pag. 106) describes 

 the spores as being 7u long, minutely prickly ( finlaggiga«). 



24. C. ozes Fr. var.{1) Plate III (ig. 2. 



Spores ovate 4 1 / 2 — - 5 x 3 u. Basidia 4-spored. Cystidia 0. 



Fig. specim.: Aarup, gregarious on the ground amongst dead 

 needles in wood of Picea, Aug. 1915. — Also found in same 

 locality 1916, and at Kirkeby, in wood of Picea, Oct. 1915 (a pale 

 form). 



As my plant diverges somewhat from the description of Fries 

 I add a short diagnosis: Cap about 2cm, hygrophanous, even
