THE ESSEX NATURALIST.
Miss Lister has also furnished the following report on the myxomycetes
found on the occasion of the Fungus Foray on October 10th, 1931 :—
About half an inch of rain had fallen during the previous week, which
no doubt had aroused a number of plasmodia from the "sclerotium"
or resting stage. Twenty-two species of Mycetozoa were recorded, but no
specimen of Badhamia utricularis, one of the most characteristic of the
Forest species, was seen, although prostrate logs clothed with its favourite
food, Stereum hirsutum, were plentiful.
The following is a list of the species found :—
Physarum nutans, Pers., on dead wood and leaves.
P. bitectum, Lister, on dead holly leaves.
Fuligo septica (L.) Gmel. ; several weathered aethalia were seen.
Craterium minutum (Leers) Fries. ; weathered, on dead leaves.
Didymium squamulosum (A. and S.) Fries. On dead holly leaves.
Colloderma oculatum (Lippert) G. Lister. On living trees ; fresh sporangia
continued to emerge during the succeeding three weeks on a piece
of bark brought back and kept moist indoors.
Stemonitis fusca Roth and S. ferruginea Ehrnb., both matured from white
plasmodia brought indoors.
Comatricha nigra (Pers.) Schroet, was found in all stages from youth to
maturity.
C. typhoides (Bull.) Rost. Abundant in dead wood.
Licea pusilla Schrad. Sporangia have continued to develop on fragments
of dead wood clothed with gelatinous algae that have been kept
moist since they were collected on the day of the foray. This species
was first recorded for Essex on the occasion of the last Fungus Foray
a year ago.
Reticularia Lycoperdon Bull. A typical large silvery aethalium was
found, and also a small rusty-brown form half an inch across (the
latter has been described by M. Ch. Meylan, in the Jura, as a distinct
species, if. jurana, but hardly on sufficient grounds).
Lycogala epidendrum (L.) Fries. Both mature and immature aethalia
were found.
Trichia varia Pers, was seen in great quantity in all stages of development.
T. persimilis Karsten, T. decipiens (Pers.) Macb. and T. Botrytis
Pers, were also found on dead wood.
Arcyria cinerea (Bull.) Pers., A. pomiformis (Leers) Rost., A. incarnata
Pers., A. denudata (L.) Wettst, and A. nutans were seen on decayed
wood.
