20 Peck: Mycologists at Scarborough, 
the Fungi was given, and the characteristics of the principle 
groups briefly discussed. It was pointed out that the Agari- 
cinee offer peculiar difficulties in the discrimination of genera 
and species, owing to the fact that the characters commonly 
used are mainly the size, colour and texture of the stem and 
pileus, the attachment, size and conformation of the gills, and 
the colour, shape, surface and size of the spores. It was 
suggested that the microscopic examination of the structure 
and arrangement of the various tissues might afford valuable 
aid in the determination of species and genera, especially in 
forms which have a very close resemblance to one another. 
An interesting discussion followed in which Messrs. Clarke, 
Cheesman, Roe, Johnson and Malone took part. 
Mr. W. N. Cheesman exhibited a collection of Fungi and 
Mycetozoa made by him last year in Australia and New 
Zealand. He pointed out the salient features of interest in 
each species and gave a description of the bush or jungle found 
at the Antipodes and other collecting grounds visited. The 
Fungi consisted mainly of polypores and resupinate Thele- 
phoracee, of which seven species new to science were recorded. 
These are described in the current number of the Kew Bulletin, 
by Miss E. M. Wakefield, and the Mycetozoa in the July number 
of The Journal of Botany. 
Mr. Peck contributed a Lantern Exhibition illustrative of 
the Fungus Flora of the district, and of interesting specimens 
met with at recent annual Forays. 
Mr. Johnson gave an account of his investigations upon.the 
Salmon disease amongst coarse fish. 
The attention of the Mycological Committee was directed 
to certain beech trees in Forge Valley believed to be suffering 
from a fungus disease, but investigation revealed the pest to 
be due to insects. Specimens were collected and sent to the 
Board of Agriculture and Fisheries who identified the Beech 
Felted Coccus, Cryptococcus fagi, the subject of the Board’s 
leaflet, No. 140. The owner expressed his intention to carry 
out the Board’s recommendations. 
Altogether 310 species and varieties were met with, divided 
into the various groups as follows :—
