 I have no doubt that the plant in question is 6". pygmaeum Wain , but at the 

 same time it must be mentioned that it does not quite come up to Walnk t's 

 description of spseudopodetia albido-glaucescentia^ all though they certainly 

 are sbasis versus nigricantia . Lhe podetia as a whole are very dark throughout 

 though portions here and there are lighter. But I do not think that in this 

 case a greater darkness in colour warrants the making of a new species. The 

 specimens from the Shetland Islands are lighter in colour and they undoubtedly 

 belong to Wainio's species.
