MycoLtocy.—Mr. A. E. Peck writes :— 
The Committee were represented by Mr. W. N. Cheesman, 
Miss C. A. Cooper and myself. Mycologists do not expect to 
meet with finds of outstanding interest at this time of year. 
At Castle Howard, Polyporus cuticularis on Beech, according 
to the writer’s experience, was unusual on this host. Hitherto 
he had only met with it on trunks of Alder. 
Fomes fomentarius occurs in the fine avenue of Beech trees 
and the writer is confident that certain specimens at the foot 
of one Beech tree are the same as were observed at the time 
of the visit of the Mycological Committee in 1909.
