12. C. Friesii Quél. 



A. Spores ovate-subrotund (slightly angular), 8V 2 — IOV2 x ^V* I 1 - 

 Sporepowder blackish-brown. 



Fig. specim.: Bramstrup, on dead Phragmites-straw, in moist 

 meadow, July 1898. 



Not quite typical and possibly a distinct species. The cap is 

 almost glabrous, slightly downy. 



B. Spores triangular-subrotund, somewhat flattened, 8 — 9X6V2H 

 (short diameter only 57 2 u), pale date-brown, translucid. 



Lundeborg, on dead grass, woodpath, Aug. 1914. — This I 

 consider the typical form. The cap soon becomes glabrous, but 

 is at first clad with small squamules, which are made up of 

 cells like those of no: 13 (which is very closely allied). 



C. var. microspore!. A form with still smaller spores (6x5 — öVaH) 

 I have met with once, growing on bits of straw (from horse- 

 droppings). Hjallese, green walk in copsewood, Aug. 1913. 



13. C. phæosporus Karst., var. 



Spores broadly oval, S 1 /*— 9V 2 x 6— 6 3 / 4 V, translucid date-brown. 

 The coating on the cap formed of light brown, thick-walled 

 filaments (4- — 5 \jl broad) with irregular, rectangular, somewhat 

 bifurcate branchlets. 



Fig. specim.: Hjallese, on loamy rubbish-heap among germi- 

 nating grass-seed, Sept. 1904 (solitary specimens). Also found 

 on green walk in foliaceous wood. 



Cap IV2 cm high, cylindric, covered, especially low r ards the 

 apex, by a rather dense felty coating, which is somewhat ochra- 

 ceous and disintegrates into small squamules, which on top of 

 cap are mucronate. Edge of cap soon minutely striate and tur- 

 ning pale lilac. During the night the cap expands, the edge 

 recurves, and the entire surface becomes striate. Sporepowder 

 dark gray-brown. When young this fungus reminds you of C. 

 comatus en miniature. 



It differs from the description of Karsten by its solitary habit, 

 from 12 B by its oval spores. 



14. C. domesticus (Pers.). 



Spores oval-ovate, gray-brown, 7— 8 X 47 2 — 5 u. — Cystidia (on 

 edge of gills only) globular, about 15 \x broad, with or without a 

 5— 16 u long, 4— 5u broad appendice (1914). — Veil formed of 

 two different tissues: the outer one made up of septate, thick- 

 walled, yellow, 8u broad filaments; the inner one of globose, 

 hyaline cells. 



Fig. specimens: Sorø, open space in wood, on the ground 

 among chips, Oct. 1901. — B. Aalykkeskov near Odense, on the 

 ground in foliaceous wood, 1911. — Not rare, on the ground, 

 especially among chips; also an decaying doorsills etc.
