CLASSIFICATION 249 



ACETABULARIA 



The single species constituting this genus has only been met 

 with once, about a century ago. It was described and figured by 

 Sowerby, one of the pioneers in British mycology, and is retained 

 in the hope that someone may succeed in finding it again. It has 

 been suggested that it should be omitted from the list of British 

 fungi, as being something spurious. This, however, in the light of 

 other fungi described many years ago by Bolton, another pioneer 

 in the study of fungi, being considered as doubtful, have recently 

 been rediscovered, and the original description and figures proved 

 to be correct, by Mr. C. Crossland of Halifax. 



Pholiota 



This genus includes some of our most beautiful species of fungi, 

 the colour ranging from deep orange to clear, bright yellow, and 

 often furnished on the cap and stem with large scales, which always 

 adds so much to the appearance of a fungus. The ring on the stem 

 is constantly present, and in most instances is well interwoven or 

 compact, and persistent. In Flammula, a closely related genus, the 

 ring, if present, is only loosely fibrillose, and never forms more 

 than a silky zone round the stem of the mature fungus. In Cor- 

 tinarins, again, the secondary veil is only cobweb-like, and never 

 forms a membranous ring. 



Pholiota agrees in structure with Annillaria in the Leucosporeae, 

 and with Stropharia in the Melanosporeas. 



Pluteolus 



The two species included in this genus are easily recognized by 

 the perfectly free gills and thin, viscid cap. 



Corresponds with Schulzeria in the Leucosporea, Clilorospora 

 in the Chlorosporeae, and with Pluteus in the Rhodosporere. 



BOLBITIUS 



A very remarkable genus, approaching Coprtnus in the early 

 deliquescence of the gills. All the species are slender, and disappear 

 very quickly. Clear yellow to bright orange are the predominating 

 colours. 



Inocybe 



A very large genus, the species of which cannot be identified with 

 certainty, without microscopic examination, on account of a general 

 superficial resemblance between what are in reality very distinct 

 species. The characters of most importance in the correct dis- 

 crimination of species are the spores, whether warted or smooth, 

 and the presence or absence of cystidia in the gills. Bright colours 

 are absent, dingy brown being the predominating tint. Some
