Yorkshire Bryological Committee.— Mr. W. Ingham, 
B.A. , writes: — The year 1905 has been a very successful one for 
Mosses and Hepatics. 
The excursions to Ripon, Askrigg, and Pocklington were 
attended by members of this Committee, and detailed reports 
have appeared in the " Naturalist." 
The most noteworthy plants discovered during the year are 
as follows : — Lopliosia iiiHata var. compacta Nees on a mass of 
millstone grit in Shipley Glen, Bradford, 13th February, 1905, 
and var. laxa Nees on the moors between Buckden and Arnclifte. 
Aplo5iii Goiilanii (Husnot) near Falling Foss, Robin Hood's 
Bay, a Hepatic new to the British Isles, and found by me on 
1 6th Sept., 1905. Pedinophyllum interruptinn var. pyrenaicum 
(Spruce), on rock ledges by Redmire Fall in Wensleydale, June 
1905. This habitat and the one at Malham in 1857 by Carrington 
are the only records for pyrenaicum'' in the British Isles. 
Of mosses, Hypniim vernicosiim is plentiful among the Globe 
Flowers and Bird's-Eye Primroses at the side of Semmerwater, 
and is w^orthy of record as a definite locality for a rare and 
obscureh- understood moss. 
In the June " Naturalist," an important new variety of 
Hepatic was described and illustrated.
