only that it was the same species but must have been collected 

 under precisely the same conditions, in fact, it appeared to be 

 part of the same collection. It seemed impossible that plants not 

 known to be cosmopolitan could have developed in regions so 

 remote and of so different environmental conditions as in Ceylon 

 and Ohio and have produced such perfect identity of characters. 

 Two plants could not possibly be any more perfectly alike. 

 Knowing that Cooke had received some of Morgan's specimens, it 

 seemed too probable that there had been an error in labeling and 

 that the specimen should have been marked Ohio instead of 

 Ceylon. Later, however, at South Kensington in the Broome 

 Herbarium there was found a specimen just as perfectly iden- 

 tical with the Morgan specimens as was the Cooke specimen 

 and this was marked Hydnum Ceylon. G. H. T. 1854." 

 There appeared to be no reason to doubt that this was truly a 

 Ceylon plant and hence that the Cooke specimen was also cor- 

 rectly labeled. It seems, therefore, conclusively demonstrated 

 that plants identical in every respect with the type of Steccherinum 

 Morgani were collected in Ceylon by G. H. K. Thwaites between 

 1854 and 1868, and that No. 385 is in all probability one of these 

 plants. 



. The South CaroHna plant of Ravenel, No. 1634, does not belong 

 to this species. It is also evident that Berkeley had the Ravenel 

 plant in mind as the type of his H. glahrescens not only from the 

 fact of his having described the species in a work on North 

 American fungi, but also from the fact that when he placed any 

 name on the Ceylon plants it was with the ascription " B. & 

 Rav." or " B. & R." It seems clear, therefore, that the name was 

 first given to the American plant and the Ceylon specimens were 

 then referred to this species, as we believe, erroneously. 



Steccherinum laeticolor (Berk. & Curt.) 



Hydnum laeticolor Berk. & Curt. Grev. i : 99. 1873. 



The type of this species according to the citation of Berkeley 

 is Curtis 2930, with which are associated other specimens from 

 the South, as Beaumont 4647, 5166, and Ravenel 894. These 

 specimens are all in the Berkeley Herbarium at Kew. The 

 species as thus represented is a clearly defined segregation some-
