Mr. E. M. Holmes on the Saturday paid some attention to the Mosses,
Lichens and Hepaticae, and he has kindly furnished the following lists of the
species observed. Mr. Holmes remarks:—"These lists are the result of only
three hours' wanderings around the lake in Hatfield Forest. So far as I can
judge from the mosses and lichens found I am inclined to think that where the
chalk comes near enough to the surface to render the soil calcareous, many more
species might be detected in early spring, as also in the boggy ground near the
lake. The lichens, though abundant, do not fruit freely. The commonest species
occurring on trees are :—Pertusaria amara and P. globulifera, Lecidea canescens,
Ramalina fraxinea, R. farinacea and Calicium hyperellum, frondose species being
