and Nolanidei of Fries) besides some few species of Nolanea and 

 Eccilia. To the latter the group Leptonidei of Entoloma, all the 

 Leptonias and the majority of the Nolaneas and Eccilias. Besides 

 these two types (with small variations within each type) we 

 have in Nolanea pascua (and some few other species) a third: the 

 quadrangular-stellate or almost cruciform spore. 



2-spored basidia are rare. Nolanea cetrata is constantly 

 twospored (as already observed by Schroeter). In Leptonia cha- 

 lybæa the number appears to vary (even on the same gill) from 

 two to four, three being the ordinary number. In the specimens 

 of L. euchlora which I have investigated the number of sterigms 

 was 2 — 3 (but I have only found this species once). 



Cyst id i a are rarely met with; and when present they are 

 generally very trivial: hairshaped or subcylmdric. 



Classification. The numerous species of the genus Rho- 

 dophyllus represent comparatively few types. Many species are 

 almost too intimately related to deserve specific rank. This is 

 especially true of the Entolomæ Nolanidei Fr. From E. clypea- 

 tum through E. rhodopolium, E. nidorosum etc. to E. speculum 

 all the species form a chain of almost imperceptible links. And 

 when this holds true of the living plants themselves the case is 

 of course still worse when it comes to recognizing and di- 

 stinguishing species from figures and descriptions In the figure 

 the minutiae which characterize the different species (shades of 

 colour, villosity etc.) are either entirely lost or accentuated out 

 of all proportion. — It is therefore rather difficult to attain to 

 a fully correct identification and naming of the species found. 

 Still I hope that my list will not show many serious mistakes. 



The number of Danish Rhodophylli appears to be compara- 

 tively large. The number of species found and figured by me 

 is 47 (besides some few species which I have not found in a 

 condition fit for portraying). — Fries in Hymenomyc- Europ. 

 enumerates 69 species (including the angular-spored Clitopili 

 and Eccilias) which he has seen himself. And Ricken (loc. cit.) 

 has about eighty (besides some dubious natives) for all Central 

 Europe. - The species mentioned by me are not all the Danish 

 Rhodophylli. Sev. Petersen (loc. cit.) describes several species 

 — f. inst. Leptonia formosa, L. solstiiialis, Nolanea codes, N. vina- 

 cea and Eccilia parkensis — which I have not met with. Thus 

 probably the total number of Danish Rhodophylli is considerably 

 above 50.
