(short diameter 6V 2 u)- Cystidia vesiculous, sackshaped or some- 

 what bottleshaped^ 25 [i broad. Surface of cap formed of 

 balloonshaped, hyaline cells (20—35 u diam.). 



Fig. specim.: Hjallese, old lawn, July 1897. — Very common 

 in grass. — In woods (on foot-paths etc.) a paler, more campanulate 

 form is not uncommonly met. This probably is the C. hemero- 

 bhis of Fries. But I do not think it specifically distinct. Fries 

 places the two species in different groups; C. hemerobius he 

 regards as glabrous, while C. plicatilis is placed in »furfurelli«. 

 But as a matter of fact both are perfectly naked. 



32. C. miser Karst. (Plate I, fig. 1). 



Spores subrotund-lriangular, somewhat flattened, 8 x 7 (a (short 

 diam. 5(a), black, impellucid. Surface of cap formed of ovate- 

 globose, about 18 n broad cells. 



Fig. specim.: Aalsbo, on cow-dung in pasture, under Betulas, 

 Oct. 1899. — Apparently not rare, on cow-dung in copsewoods 

 and pastures, but easily overlooked. 



This very minute species I formerly referred to C. Schroeteri 

 Karst, (sensu Schroder), but it has much smaller spores. I refer 

 it now to C. miser Karst., although the author describes this 

 species simply as »hyalino-cinerellus« and does not mention 

 that the young, unexpanded cap is more bright-coloured, orange 

 or tile-red, especially towards the apex. From minute specimens 

 of the C. ephemerus-iype it is most easily recognized by being 

 absolutely glabrous, and by the spores. 



Besides these 32 species some few others are recorded from 

 Denmark. 



C. oblectus (Bolt.) is mentioned by E. Chr. Hansen as found 

 on manured ground near Copenhagen in 1875. It has not been 

 observed since. — Ricken (loc. cit.) regards it as a mere form 

 of C. sterquilinus. 



C. alternates (Schum.). This species has not — as far as I 

 know — been met with since the time of Schumacher (a. 1800). 

 It seems to be variously conceived by the different authors. 



C. deliquescens Fr. is recorded by Sev. Petersen (loc. cit.) 

 from Slagelse Skov. Cooke's figure of this species has very 

 much in common with some forms of C. atramentarius. 



C. digitalis (Batsch). Also recorded by Sev. Petersen from 

 Slagelse, bul regarded by him as a dubious species.
