17. C. niveus (Pers.). 



Spores lemon-shaped-subrotund, slightly flattened, about 12 — 18 x 

 10— 12 u (short diameter 8 — 10 ja). 



Fig. specim.: Hjallese, on horse-dung (Oct. 1898) and cow-dung 

 (Sept. 1899) in a grassfield. Common in green fields and other 

 pastures. The »C. niveus« mentioned by Massee (loc. cit.) seems 

 to be C. Rostrupianus (Conf. E. Chr. Hansen, 1897); his »C. ster- 

 corarius« is C. niveus. 



18. C. narcoticus Fr. 



Spores ellipsoid, blackish-brown, 12 — 1372 x 6V2 M> opaque, with 

 a hyaline epispore. When deprived of the epispore the spore 

 is narrowly ellipsoid, 1 1 1 / 2 x 5 1 / 2 }x. Cystidia subglobose, 20 — 40 u. 

 The mealy papillose coating is formed of globular, 35 — 80 ^ 

 broad cells, which are sparely and minutely warty. 



Fig. specim.: Hjallese, on the ground (in copsewood) on 

 mouldy, rubbish-mixed soil, a number of specimens, July 1914. 



This species has very much in common with C. stercorarius, 

 but has no sclerotia. When cut it expands a very disagreeable, 

 nauseating odour. — To judge from the description C. inamoenus 

 Karst, is identical. 



19. C. stercorarius (Bull.). 



Spores oval, 10 X 57 2 H- Cystidia sack-shaped. Veil formed of 

 large globular or ellipsoid cells, which at first are somewhat 

 warty-granulate, diam. 30 — 70 u. 



Fig. specim. : Hjallese on the ground in richly manured 

 garden-beds, July 1898. — Not very common. Also found in loose 

 horse-dung used as topdressing on the ground in palmhouse 

 (Copenhagen 1914). 



This fungus (always?) springs from a small black Sclerotium. 

 For full description and synonymy see E. Chr. Hansen's paper 

 (1897). 



Evidently C. tuberosus Quel, is identical. The same may be 

 true of C. cineratus Quel. — (C. stercorarius, sensu Massee, is 

 C. niveus). 



20. C. velox God. 



Spores ellipsoid, 1 : % — 9 x 4 1 / 2 u, dark brown. Cells on surface 

 of cap globular, warty, 24 —40 |u diam. 



Fig. specim.: Hjallese, on cow-dung in pasture, Oct. 1904. 



This species is very closely allied to no. 19, but very minute 

 (cap only 1—3 mm high, when expanded 2—6 mm); stem 

 IV2 — 2 cm x 1/4 mm, villous (especially towards the base); 

 sclerotia none.
