284 THE UREDINEAE AND USTILAGINEAE OF ESSEX:
Messrs. Cooke and Varenne in brackets after the name I have
used, or after the initial indicating the form to which they refer
in my list, wherever such names are different from those used in
the present compilation. In one or two cases in Dr. Cooke's
lists I am unable in the absence of specimens to say precisely to
what forms the names refer.
The following list contains records of 85 sp. out of about 260
given in Dr. Plowright's monograph ; Dr. Cooke records 9
species not given below, and Mr. Varenne's collection includes 12
species of which no fresh records are available—these with
Puccinia bupleuri recorded by Mr. Plowright (Monograph, p. 154),
from Walton-on-the-Naze, make a total of 103 species known
from the county. This number will, on further search, doubtless
be largely augmented, although, of course, the distribution of
these fungi depends on the distribution of the host plants.
An excellent paper by Dr. Cooke on this group of plants is
published in the Essex Naturalist, Vol. iv., pp. 28-39, contain-
ing many useful suggestions on the collecting and study of minute
fungi. There is room for very considerable further work with
these and other groups of fungi in the county, and I have only to
add that it will give me very great pleasure to render any aid in
my power in naming specimens, etc., for anyone who will collect
them.
Thirty species are recorded below which do not appear in
either of the lists quoted above, including two species not
mentioned in Dr. Plowright's monograph, viz., Puccinia acetosae
Schum., and Melampsora orchidi-repentis Plow. These new
county records are indicated by an asterisk * ; in the cases where
the host plant upon which the parasite is growing is not men-
tioned in Dr. Plowright's book, a dagger † is placed before the
name of the host.
The following abbreviations are used :—
AE indicates aecidium form.
U ,, uredospore ,,
T ,, teleutospore,,
The initials in brackets after the names of the localities indicate upon whose
authority the record is given :—
H. indicates Mr. A. W. Heaver, of Maldon.
T. „ ,, E. E. Turner, of Coggeshall.
W. „ ,, H. Whitehead, of the Essex Field Club Museum.
C. „ Myself.
