often cut into narrow lobes, whereas in the allied genus 

 Lachnodadium^ which grows erect from a short, stem-like 

 base, the branches are so narrow and so numerous that 

 the species are superficially confounded with branched 

 species of Clavaria. The mistake is corrected on exam- 

 ining a section which in Lachnodadium has the hymenium 

 confined to one side of the sporophore, whereas in Clavaria 

 the hymenium entirely surrounds the sporophore. 



Although, as already stated> the even hymenial surface 

 is the hall-mark of the Thelephoreae, as a matter of fact 

 the genera remaining to be considered have the surface of 

 the hymenium more or less uneven, and shadowing in, as 

 it were, those features which become of primary importance 

 when fully evolved in allied families. 



CladoderriS) an exotic genus with a fan-shaped pileus 

 attached laterally by a very short stem, has the hymenium 

 rugulose and more or less covered with blunt projections, 

 suggesting the more highly differentiated, blunt, tooth-like 

 projections on the hymenium of Radulum, belonging to 

 the Hydnaceae. On the other hand, Craterellus, belong- 

 ing to the Thelephoreae, has a central stem and funnel- 

 shaped pileus, and the inferior hymenium has more or less 

 pronounced veins or wrinkles running from the margin of 

 the pileus to the stem, and resembling very closely in 

 habit and general structure the genus Cantharellus, be- 

 longing to the Basidiomycetes, where the gills more 

 resemble thick, blunt-edged veins, than the thin, sharp- 

 edged gills characteristic of the last named-order. 



In the present family the spores vary from colourless, 

 through pale yellow to deep ochraceous in different genera. 



Representatives of the family are met with everywhere, 

 being most abundant in temperate regions, yet the most
