206 PI3IINA, NOVUM HYPHOMYCETUM GENUS. 



H. Langwellense. — Approaching H. angliciim Bab., but differing 

 from it in the blunter, shorter, less porrect phyllaries, subglabrous 

 ligules, and in the radical leaves, which are broader at the base and 

 abruptly decurrent. From the east coast of Caithness. 



H. poUinarmm. — Perhaps nearest to H. murorum Linn, pt., 

 differing from it in the closely-aggregated heads, the short, straight- 

 based peduncles, which are mealy with floccose down (hence the 

 name), the broader phyllaries, and the scarcely-toothed, round- 

 based, fleshy radical leaves, &c. From the north coast of Suther- 

 land. 



H. scoticum. — I purpose giving this name to the plant collected 

 in several places from the coasts of Caithness and Sutherland, first 

 in 1885, and which was recorded and distributed by me as H. nor- 

 vegicum Fr. Dr. Lindeberg now considers, that although some of 

 the specimens resemble that species in general appearance, yet 

 that others are so different that they cannot be united to it. It 

 differs from H. norvegicum in the leaves being fewer, much broader, 

 and rapidly decreasing upwards in size ; the broader, concolorous, 

 adpressed phyllaries, the outer ones of which do not descend into 

 the peduncle, and in other minor points. 



There are several other interesting forms that I hope to record 

 later on, but as I expect to revisit Sutherlandshire during July, I 



on them.

Amongst the identifications of British Hieracia I have recently 

 x^v>eived from Dr. Lindeberg are typical U. casium Fr., and H. 

 strictum Fr. I mention this because the great bulk of specimens 

 found under these names in British herbaria are wrongly so called. 



The following are, I believe, new county records : — H. argenteum 

 Fr., Caithness, 109; H.gothicum Fr., Caithness, 109; H. nitidum 

 Backh., W. Sutherland. 107.
