Yorkshire Naturalists in Coverdale 299) 
Orthothecium intricatum, Seligeria pusilla, Hypnum stellatum 
var. protensum and Bartramia Céderi ; in the streams with an 
abundance of Hypnum palustre were found Fontinalis squamosa 
and Hypnum ochraceum. In one swampy spring head what 
appeared like an uncommon Bryum, turned out to be Mnium 
stellare, a moss one associates with dry woodland walls and 
rocks ; this same moss was also seen on the rocks by the Cover 
side further down the valley. Close to Carlton it was interesting 
to see the variation of the mosses on the walls accordingly as 
they were limestone or grits. On the grit walls Hypnum 
cupressiforme was dominant, with plenty of Leucodon sciuroides, 
and a little Grimmia trichophylla, whereas on the limestone 
the dominant species is Pleuropus sericeus with Bryum cap- 
pillare, Encalyptra streptocarpa, etc., and in one place, near 
Gilbert Scar Bridge, some fine Bartramia ithyphylla. On 
limestone by some of the lower tributary streams we gathered 
Eurhynchium. tenellum. In the woodland by Coverbridge 
mosses were luxuriant ; on the walls of the roadway we made 
the most interesting find of the day, a moss, Neckera com- 
planata, which is extremely frequent in these places but barren, 
was found in very good fruit, the Mnium stellare, before 
mentioned, was also on the walls in its typical state. Some 
damp limestones with tufa had Weisia verticillata in good 
fruit as were Barbula tophacea and Hypnum commutatum. 
A small Eurhynchium gave some trouble and had to be sub- 
mitted to Mr. W. Ingham who determines it as E. pumilum. 
This moss is a new record for the drainage area and was in the 
fruiting state. Mnium cuspidatum was well grown and 
fruiting, and so was Homalia trichomanes. An adjournment 
was made to the stream side and the rocks examined ; Hypnum 
molluscum var. fastigiatum,  Dichodontum pellucidum of 
varying forms covered many of the rocks, with Barbula 
spadicea, B. cylindrica, Eurhynchium crassinervium, Mnium 
stellare, M. cuspidatum and Bryum pallens. In the afternoon 
we cycled to Jervaulx and from here we took the road through 
Masham, calling in Hackfall Woods, where another variety, 
condensatum of H. molluscum was seen with the uncommon 
Hypnum Patientia. 
MycoLtocy.—Mr. W. N. Cheesman reports :— 
Eastertime is somewhat early for many of the fungi, and 
this year the cold dry weather had the effect of retarding 
growth, but by diligent search, Mr. R. Fowler Jones and the 
writer succeeded in getting together fifty-five species of fung1 
and sixteen species of Mycetozoa, most of which were of common 
occurrence, exceptions being Urvocystis colchict, the fungal 
parasite of Colchicum autumnale, which has only been once 
previously recorded for Yorkshire (1880), and Tvemellodon 
gelatinosum growing on the underside of a pine log. This
