l62 THE ESSEX NATURALIST.
*A. incarnata Pers. On sticks and logs.
*A. pomiformis (Leers) Rost. On decayed oak.
A. nutans (Bull.) Grev. On birch log.
On the Cryptogamic Foray, November 12th, the party, after
leaving Loughton, proceeded by Loughton Camp to Monk Wood,
and thence to High Beach; the searchers for Mycetozoa, under
the guidance of Mr. J. Ross, also visited a group of old hollies in
High Wood. Heavy rain on the previous day and night had
probably washed away some of the more fragile sporangia, but
fourteen species were found. Of these Didymium squamulosum
(Alb. & Schw.) Fries, Lamproderma scintillans (Berk. &Br.)Morgan,
both on dead leaves; Diclydiaethalium plumbeum (Schum.)
Rost, weathered, and Arcyria incarnata Pers. var. fulgens Lister,
on dead wood, had not been recorded on October 12th. The
species that were obtained on both forays are marked with an
asterisk in the above list.
Besides these twenty-seven species, Mr. Ross had found in the
Forest area, during the previous few weeks, Physarum cinereum
(Batsch) Pers., P. vernum Somm. var. iridescens Lister, Cra-
terium minutum (Leers) Fries, Diderma deplanatum Fries., Trichia
decipiens (Pers.) Macbr., and Arcyria cinerea (Bull.) Pers.; and
Mr. W. D. Graddon had obtained Cribraria vulgaris Schrad. on
coniferous wood and C. argillacea Pers. on birch wood near
Buckhurst Hill. It is interesting to note that of these thirty-five
species fifteen occurred on birch wood, although several were
not restricted to birch.
A FORGOTTEN ESSEX GARDENER-BOTANIST.

SUCH names among local botanists as Fothergill, Warner,
and the Forsters are well known to members of the
Essex Field Club; not so the name of Gilbert Slater, of Leyton,
which may be due to the fact that he was an Essex man for
only seven years.
Gilbert Slater was born in or about 1753, the son of Capt.
Gilbert Slater, of Stepney, Middlesex, Deputy Master of the
