Fig. specim.: Hjallese, in copsewood on leaf-mouldy ground 

 about an old stump, Oct. 1898. — Very common on and around 

 old stumps, amongst dead foliage and rotten fungi, often grega- 

 rious. — If carefully examined the fibrinous »root« can, I believe, 

 always be traced to a Sclerotium. (Massee (European Fungus Flora) 

 erroneously states that it is devoid of Sclerotium). 



17. C. racemosa (Pers). 



Spores ovate-ellipsoid, 4 1 /* x 2 l / 2 u. 



Fig. specim.: 1) Hesselagergaard, in deep moss in a ditch in 

 young plantation of Picea, Oct. 1905. 2) Hjallese, on the ground 

 about stump of Populus, gregarious, Sept. 1 908. — 



The cap is often abortive like the rudimentary heads on the 

 lateral branchlets. Fries in »Hymenom. Europ.« says the gills 

 are white. In my plant they are hoary gray (as described by 

 Quélet (loc. cit.). 



18. C. stipitaria Fr. (Ag. caulicinalis Bull.). 



Spores ovate, 8 x 6 u (or oval 6'/ 2 x 4 or 9 X 5 u). Cystidia crowded, 

 cylindric-hairshaped, obtuse, about 4u broad. 



Fig. specim.: Hjallese, on dead tufts of grass (Dactylis), Oct. 

 1896. — Common, especially on Dactylis, from August to January. 

 I have also seen it growing on rye-stubble (Secale) (Aug. 1900). 

 In this case it must either have attacked the living rye-plant or 

 have developed very quickly in the stubble. — 



It is also occasionally met with on dead stems of Syringa 

 (Gudbjærg, January 1900) and on dead twigs of Picea (Vormark, 

 Oct. 1901.). 



This tiny little plant is very much like a Marasmius. According 

 to Quélet M. scabellus (Alb. & Schw.) is identical. But he describes 

 tliis latter species with »spores sphériques, 12 u, pointillées«. - 

 M. epichloe Fr. also appears to be identic. 



B. TEPHROPHANÆ. 



19. C. rancida Fr. 



Spores ellipsoid, 7 — 8 X 4 1 /* u. 



Fig. specim.: Hjallese, wood ofQuercus and Corylus, Oct. 1896. 

 Rather common, but solitary, chiefly in deciduous woods, till 

 late in the season It has a superficial likeness to Mycena poly- 

 gramma. 



20. C. inolens Fr. 



Spores ellipsoid, 7 — 8x4 — 5 u. 



Fig. specim.: Hæsbjerg, somewhat gregarious on the ground 

 in wood of Picea, Oct. 1899. — Not. common.
