which deviate from the normal Pholiota-type and branch off 

 into Hebeloma (P. radicosd), Cortinarius (P. caperata) etc.; but 

 also such a typical Pholiota as P. speclabilis has rough spores. 



Cystidia are found in most species; but in most cases they 

 are rather trivial: obtusely hairshaped or slightly clubshaped. 

 In a few cases they are vesiculose or inflated-bottleshaped (f. inst. 

 P. prcecox). Another characteristic type of Cystidium is that 

 found in P. squarrosa: obovate-clubshaped, generally tipped with 

 a short cylindric-hairshaped appendix. 



The number of Pholiotas figured in »Danmarks Agaricaceer« 

 is comparatively small, only 18, while Fries in »Hymenomycetes 

 Europæi« enumerates 47 (of which 37 seen by himself). The 

 geographical position of Denmark is too northern to give us a 

 fair representation of the South-European tribe Aegerilini. And 

 our woods — nearly all of which are under rational cultivation 

 by the forester (old stumps lifted, superannuated and sick trees 

 not allowed to stand etc.) — are a rather poor home for xylo- 

 philous fungi. 



Still the number of species could undoubtedly be added to. 

 ThusSEv. Petersen (Danske Agaricaceer) records P. sphaleromorpha 

 and phragmatophylla as well as P. terrigena and P. muricatu. And 

 I myself have seen a specimen (from Sjælland) of a xylophilous 

 Pholiota which probably was P. aegerita. If these be added the 

 number of Danish species approaches very much that of the 

 Central-European Pholiotas recorded by Ricken (27). —
