274 Yorkshire Naturalists at Burnsall. 
sylvaticum, Trollius europeus, and Crepis paludosa were notice- 
able features of the flora. 
MycoLocy.—Mr. C. Crossland writes :—Between twenty 
and thirty species of fungi, including Agarics, Polypores, 
Uredines, Pyrenomycetes and Discomycetes, all of common 
occurence and wide distribution were sent me by Messrs. 
Malone, Broadhead, and F. A. Mason. Mr. Mason, however, 
a few days later wrote me that he had exposed three prepared 
dishes in the hope that spores floating in the air might 
be caught and developed on the gelatines prepared for them. 
Mr. Mason sends me the names of some of the fungi which 
have so far developed on the dishes :— 
1. Oospora lactis. 5. P. olaraceum. 
2. Monilia variabtlis. 6. Botrytis cievrea. 
3. Aspergillus glaucus. 7. Saccharomyces ellipsoideus. 
4. Penicillium glaucum. 
Nos, I, 2, 5, 7, are not previously recorded in the Yorks. 
Fungus Flora. The beautiful Thamnidium elegans found on 
insect excreta has only one record in the flora. 
Mr. Mason has three others grown on the prepared dishes 
not yet identified. 
BryoLocy.—Mr. C. A. Cheetham writes :—The mosses seen 
in Trollers Ghyll were of the usual type associated with a lime- 
stone gorge. In the stream at the bottom of the valley Eur- 
hynchium rusciforme took the main place with Amblystegium 
filicinum and Hypnum falcatum var. virescens. On the stones and 
sides of the stream were Bryum pseudo-triquetrum, B. bimum, 
B. pallens, Philonotis fontana and Wetsia viridula. On the 
vertical walls of the ghyll the most interesting were Tvichos- 
tomum mutabile var. lophocarpum, Seligeria pusilla, Eurhynchium 
tenellum, Mnium orthorynchum, and the hepatic, Madotheca 
laevigata. 
Where tufa was being deposited Weisia rupestris and Hyp- 
num commutatum were frequent. In one or two places 
Encalypta vulgaris was in fine fruit and on a solitary grit boulder 
in the midst of limestones a patch of Ptychomitrium poly- 
phyllum was in good fruit, this moss is no lover of limestones 
and it was interesting to see it here, we did not meet it again 
even on the grit area. Above the limestones the mosses 
changed quickly, on the clayey banks of the stream, Dicranella 
varia was abundant and asmall patch of Bryum filiforme was 
- noted. The bed of the old Skyreholme dam had a fine growth 
of the var. elatum of Mnium affine and the grit rocks had 
Dicranium scoparium and Campylopus flexuosus, these two 
with the hepatic Lophozia Flerkit were the only rewards of a 
scramble up the grit scars above. While crossing the cotton 
grass area midst Sphagnum and Polytrichum commune we got 
a few tufts of Polytrichum strictum.
