THE ESSEX NATURALIST.
Tea was served shortly before 5 o'clock, following which a short
meeting of the Club was held, with the President in the chair.
The President referred to the lamented death, as the result of a street
accident, of one of the Club's honorary members, Dr. B. Daydon Jackson,
and on his proposition it was agreed to send a letter to Mrs. Jackson, ex-
pressing the condolence of the Club. Reference was also made to the loss
sustained by the Club in the recent decease of our member, Mr. St. John
Marriott, a zealous worker among the hepatics.
The President then called upon our Referees for their reports on the
finds of the day.
Mr. Gould remarked that, notwithstanding a paucity of numbers,
which was rather surprising after what seemed to be a most favourable
season as regards weather, the collection made that day was highly
representative.
Mr. Pearson reported that, seeing that his list of fungi found that day
reached a total of at least 140 species, the yield was quite up to or even
above that of past years.
Mr. Ramsbottom thought the comparative scarcity of specimens
might be due to the fact that although the mycelium of a fungus is
constantly growing, it may fruit but once in a season ; were this not
so we should have a constant succession of fungi over a long period, which
does not seem to be the case. It was noteworthy that Laccaria laccata
and Clavaria cinerea had been most abundant that day, while the common
species, Paxillus involutus, had been very rare.
Miss Lister was quite satisfied with her bag of myxomycetes, a goodly
haul of 25 species having been recorded during the Foray ; one form
found was a new record for Epping Forest (Didymium Listeri, Massee).
Mr. Paulson called attention to the specimens of "fungus-root"
(mycorrhiza) which he had collected : he said this was not the ordinary
roots of the tree, but a horizontally-spreading network of modified rootlets,
close beneath the surface of the soil, composed of an association of fungus-
hyphae with the tree-root, which appeared to be a case of symbiosis, since
it was clear the fungus did no harm to the tree. Over one hundred fungi
were now known to produce mycorrhiza.
Votes of thanks to the several Referees were passed by acclamation, on
the President's motion, and the meeting terminated.
Mr. Pearson reports later that the total yield for the day was 145
species of fungi, most of which belonged to the Basidiomycetes. Of these
the following were first records for Epping Forest, viz. :—
Clitocybe vibecina Fr.
Nolanea cetrata (Fr.) Schrot.
Clavaria corniculata (Schaeff) Fr. (=C. muscoides Fr.)
Corticium flavescens (Bon) Massee.
Tulasnella microspora Wakef. & Pears.
Sebacina sphaerospora Bourd. & Galz,
The last-named has only recently been recorded from Britain ; a
description of the species is therefore appended :—
