WITH A CATALOGUE OF THE SPECIES.
253
dozen more species in this subgenus should be found in the Forest.
Of the subgenus Flammula one new species, Ag. decipiens, was
found and described by Worthington Smith. Under the subgenus
Naucoria is generally included Ag. subglobosus A. and S., one of the
least known of Agaricus, of which Fries himself seems to have been in
doubt. It was found in the Forest during the present year (1888) for
the first time in Britain, and if our determination proves correct, it
should be included in Nolanea, instead of Naucoria, as the spores
are pale, and salmon coloured. We are not aware that, in the
subgenus Galera, Ag. rubiginosus and Ag. mniophilus have been
found in Britain elsewhere than in Epping Forest, and Ag. (Tubaria)
stagninus only at High Beach.
The purple-spored section, Pratelli, does not contain many Epping
varieties. Of course amongst these must be included Ag. (Stro-
pharia) worthingtoni and Ag. spiniriger, whilst Ag. (Hypholoma)
epixanthus and Ag. dispersus are very local, if not rare. No other
species requires mention.
Amongst the black-spored species we have nothing of note.
This brings us to the deliquescent Coprini, in which the gills
dissolve away to an inky fluid. In this genus C. aratus B. is rare,
but was found in Monk's Wood. Coprinus congregatus was not
recognized in Britain until it was found in Epping Forest.
The beautiful but rather difficult genus Cortinarius, with a veil
like a spider's web, is fairly represented in the Forest. C. albo-
violaceus was first found and recorded here, but has since turned up
in various other places. A similar species, C. argentatus, also first
put in an appearance at Chingford, and, up to now, it has only been
found there. Cort. renidens also has been found nowhere else in
Britain. Cort. lepidopus was an entirely new species found during
the same year, both at Epping and two other widely separated
stations. It is most likely that a great accession will yet be made to
this genus in the Forest.
It is unnecessary to refer at length to Hygrophorus, as most of the
Forest species are common. Except, perhaps, H. chrysodon from
Monk's Wood, and H. russo-coriaceus, with the odour of Russian
leather, from Monk's Wood and High Beach.
The species of the genus Lactarius, or the milky Agarics, are very
well represented. Many of the common species are very common,
and some of the rarer ones have been found, now and then, such as
L. lilacinus, L. subumbonatus, and last, but not least, Lactarius
