mycetes, and Ascomycetes, especially the Tuberacei. (A list of 
these groups is appended.) 
The best time of year to search for Fungi is undoubtedly from 
July to November, although some may be found during the rest of 
the year. 
The Tuberacei are probably neglected because very little indi- 
cation of their presence underground is to be observed except by the 
eye of an expert. On digging up the mould under oak and fir trees 
their presence may sometimes be detected when the dead leaves are 
scraped away, by the appearance of a mycelium on the top of the 
soil, but more easily perhaps by the fact that the mould when dug 
up exhibits here and there firmer masses, due to its being com- 
pacted together by the nearly invisible mycelium, and these lumps 
when broken open show the more or less globular fungi inside. 
4, Lichens.—tThe Lichen flora of the county is by no means 
exhausted. The subalpine and alpine species are those in which the 
county flora is naturally deficient, although singularly enough the 
gravel beach at Lydd, which is only a few feet above the sea level, 
furnishes a larger number of subalpine species than any other part 
of the county. Species which in Devon and Cornwall occur on the 
borders of Dartmoor are here scattered over small prostrate bushes 
which, dwarfed by the rough winds that sweep over the level ground 
of Romney Marsh, rarely reach more than a foot and a half in 
height. 
The other groups that are not well represented are those which 
might be expected to occur on limestone walls and old ruins and on 
aged trees in parks. The limestone district of the Lower Greensand 
and the wooded districts alluded to under mosses, are those most 
likely to furnish species new to the county. 
As a rule wooded districts a few miles from the sea are the 
richest for lichens, especially in damp valleys and on isolated trees 
exposed to the light and air. Oak trees in particular are furnished 
with a great number of species. Within a radius of about twenty 
miles from London, lichens are, as a rule, imperfectly developed, the 
smoke of towns being particularly detrimental to their growth. 
Where lichens are abundant, as a rule, the 8.W. side of a tree is 
the richest, and the S.W. side of the county is likely to yield more 
than the eastern. 
5. Marine Algae.—No list of the marine algae of the county 
has been published so far as I am aware. Mr J. T. Neeve of Deal 
has explored the neighbourhood of that town with remarkable 
success, having detected a species new to science, Gonimophyllum 
Buffhami,as yet found nowhere else, although the seaweed Weto- 
phyllum laceratum, upon which it is a parasite, is quite a common 
species on the English coast. The neighbourhood of Folkestone
