Bresadola (Fungi tridentini, tab. 198 1_ -) figures two types, a 

 dark fuscous and a somewhat ochraceous one, which he calls 

 C. conigena and C. esculenta and takes to be included in the 

 Ag. tenacellus of Persoon (C conigena in the Friesian sense he 

 evidently does not know). — II seems to me somewhat doubtful 

 whether they can be kept apart. The chief difference appears 

 to be the colour of the cap and the form of the cystidia. But 

 as stated above the form of* the cystidia varies even on the same 

 gill. C. conigena sensu Ricken (loc. cit.) is my C. tenacella. 



13. C. confluens (Pers.). 



Spores ellipsoid, base rather pointed, 6'/ 2 x 3 x /a u ( or 7 V2 x 3 Z U)- 

 Cystidia hairshaped, somewhat nodulose. 



Fig. specim.: Hjallese, in wood ofFagus, on the ground among 

 foliage, Oct. 1896. 



Common, as well in woods of Fagus as of Hcea, densely 

 fasciculate (often growing in large circles) amongst dead foliage. — 

 It varies very much in colour according to age and atmospheric 

 conditions. When dry it is pale, and when old dry specimens 

 revive in wet weather they become sordidly incarnate or brownish. 

 It forms a transition to Marasmius. And like Schroeter (loc. cit.) 

 I do not see any real difference between this plant and Marasmius 

 argijropus (»archyropus« auct. div.). 



14. C. conigena (Pers.). 



Spores ellipsoid-ovate, very small, 3 x l 3 / 4 u (or 'd l j 2 X l 3 / 4 — 2). Edge 

 of gills with obtusely fusiform, about 7 |a broad cystidia (the 

 free part of the cystidium is about 25 p long). 



Fig. specim.: Trolleborg, on cones of Pinus, Oct. 1898 (and 

 later years). — Found in several places. Unlike C. tenacella it 

 prefers cones of Pinus. Only once I have met a few specimens 

 growing on a cone of Picea excelsa. Cookes figure (loc. cit. 

 tab. 30) is excellent. See also no: 12. -- Collybia nujosuras, to 

 judge from the descriptions of Fries, Ricken and others, is too 

 closely related to C. conigena to be maintained as a distinct 

 species. 



15. C. tuberosa (Bull). 



Spores subglobose-ellipsoid, 3— 4 x 2— 3 u or 4— 5 X 2 3 / 4 (ßg- 

 specim.). 



Fig. specim.: »Vaasemose«, in mixed wood on the ground 

 amongst sticks and foliage, Oct. 1901. — Rather common, gene- 

 rally growing on dead mushrooms (Lactarius deliciosus, Russula 

 nigricans etc.). The form and colour of the Sclerotium most 

 clearly distinguish this species from C. cirrhata. 



16. C. cirrhata (Schum.) 



Spores ovate-ellipsoid, 4—6 x 2—3 u (or ovale, 4 1 /, x 2 s / 4 ). Cy- 

 stidia
