4. LICHENES. (Lichens.) 
By O. V. Darbishire, M.A.- 
The lichens found in the Gardens are very few in number, not 
only of individuals but also species. They are, furthermore, as a 
rule very poorly developed, a condition of things very generally 
prevailing near and in towns 
Of the species mentioned in the following list, Lepra ibe 
alone appears to be in a flourishing PIRE in the Garden To 
it is due the green colour comm only se n the bark of older 
trees and on wood palings. It is an DAE Tre consisting 
of masses of green algae enveloped by a thin coat of fungal hyphae, 
but never producing any fruit. Lecanora crenulata seems to be 
fairly well distributed on limestone rocks and building stones, 
otherwise the specimens are mostly dwarfed and scanty. 
Most of the species where no locality is given were found in 
the rock garden, but nearly every bit of limestone bears small 
apothecia of Lecanora crenula
