known on the Continent, and chiefly, he thought, confined to Europe.
The form was very different from all others allied to it, having the pilei
of a circular discoid form with a stem in the centre, and all the stems
united in a common base. He had often wondered why it was that it
should be found in the northern parts of Europe, but never in this
country. It was here at last, and Epping Forest and Mr. English had
the honour of having added it (Polyporus umbellatus) for the first time
to the British flora. [Applause.] In the last volume of the ' Transac-
tions ' (vol. ii., 181), 338 species of larger Fungi had been enumerated
as having been found at Epping. That was then stated to be only a
first list, to which they hoped soon to make additions. He had a list of
altogether 41 additions made since the publication of that list, and he
hoped before they got to the end of November to increase that number,
so that there might be published a substantial supplemental list. Dr.
Cooke then referred to another species new to Britain—Agaricus
(Pleurotus) acerinus—collected by Mr. Worthington Smith on tree stumps
in Walthamstow, and to the finding of Agaricus (P.) corticatus on old
trunks in the forest, a species new to the district. It was also pleasant
to note the re-occurrence of Agaricus (P.) mastrucatus in the forest,
which had not been seen since Sowerby's time. But perhaps of still
greater interest were two comparatively small species, new to Science,
which had been found in Epping Forest, for the first time anywhere.
One was a small species with a bell-shaped pileus, resembling very much
the form called by mycologists Agaricus psathyra; but the spores in the
latter were dark-coloured, whereas in the new species they were un-
coloured, and the whole plant was of a white hue. It had been named
by him (Dr. Cooke) Agaricus (Collybia) psathyroides, from its resem-
blance to the above-mentioned species, and was first found in Epping
Forest in October, 1880, growing on the ground. The other species,
which was also entirely new, had been found by himself last year at
Chingford when out with the Hackney Microscopical Society. It was a
wretched day, something like the one they had had that day—an aqueous
day. [Laughter.] At the bottom of some bushes, amongst leaves, a
species of the sub-genus Mycoecna, small but interesting from its dark-
coloured pileus, was found. Shortly afterwards the same species was
sent to him from Sussex, and he had figured and described it under the
name of Ay. (Mycena) pullatus. He thought they might congratulate
themselves as members of the Essex Field Club on good work that was
being done in the investigation of the mycological flora of Essex.
In conclusion Dr. Cooke made some remarks with respect to the
fresh-water Algae of the Epping districts, of which up to the present
there had been no record in the ' Transactions.' During the last year-
he had been paying attention to that section of the Fresh-water Algae
called Chlorophyllophyceae. In this section he had a list of thirty-six
species found in the forest districts, and about eighteen Desmids. The
list was a small one, but it was very good considering he had had only
