var. nana, which also grows near Marske Mill, Saltburn. The 
two wide-spread plants Conocephalum conicum, and Pellia 
eptphylla were frequent in the wood. 
MossEs.—Roseberry Topping was almost devoid of mosses, 
the only one seen being the ubiquitous Tortula muralis. Ona 
sloping bank near Great Ayton was plenty of Polytrichum 
urnigerum in abundant fruit. In Kildale Wood were Hypnum 
exannulatum var. pinnatum growing with the large H. crenulata 
above mentioned, also a stout form of Hypnum stramineum 
simulating H. sarmentosum in habit. 
MycoLocy.—Mr. Crossland writes :—The three mycologists, 
Mr. Gibbs, Miss C. A. Cooper and the writer devoted one of the 
days to a short length of Airyholme Woods lying in the hollow 
between Easby Bank and Roseberry Topping. The tree 
denizens are spruce with a sprinkling of alder, poplar and elder, 
with larch on the sides of the slopes. Apart from the circular 
beds of fallen fir needles the floor of the wood was richly car- 
peted with moss and moisture-loving phanerogams. There 
were several little piles of half-rotten, moss grown, pine logs, 
typical breeding grounds which a mycologist loves to investi- 
gate. Here we had a really good time at very little trouble. 
Among the larger species were several fine tufts of the anise 
scented Lentinus cochleatus, and many sporophores of Poly- 
porus varius. Here also,were found eight of the ten mycetozoa. 
The species noted in Airyholme are marked A. 
Miss Cooper and Mr. Gibbs joined the party in Kildale on 
Monday. The fungi gathered in that locality are marked K. 
The remainder were noticed about Great Ayton. At Easby a 
quantity of young Populus canescens arising from suckers were 
affected with Melampsora aecidioides, the bright orange spots 
of the disease giving the leaves a peculiar appearance. 
Pasture species were scarce, probably on account of the 
dry weather. The pasture and dung fungi were all found in 
the vicinity of Great Ayton. 
The 132 species met with are here classified according to 
habitat. The names are asin the Yorks. Fungus Flora. Those
