LICHENS OF HASLEMERE DISTRICT. 
By H. H. Knight, M.A. 
Most of the lichens in this list were found growing on trees 
or palings. There are no exposed rocks in the neighbourhood 
of Haslemere, and the few saxicolous species were seen on stone 
walls near farm-houses. 
A few of these lichens were seen on 
Hindhead, the majority come from the Sussex woods visited 
during the meeting.
