DISCOMYCETES RECORDED IN ESSEX.
By W. D. GRADDON, B.Sc.
[Read 27th January, 1940.]
NO list of the species of discomycetes recorded as occurring
in our County has appeared since 1888, when M. C. Cooke
published in this Journal4 a list of 56 species. Since that time
records have accumulated all too slowly, and the list which is
here presented contains only 135 names—a poor representation
of the total of about one thousand species known for the whole
country.
Very many of the species have been only once recorded, and
many of these single records date back to early days, even to the
times of John Ray and Edward Forster. There is therefore
much scope for diligent searchers after these attractive fungi
to re-establish the occurrence of many of the species listed
and to provide additional records which will help to bring our
knowledge of this group up to the high level of that of the
Basidiomycetes and Myxomycetes of Essex.
The nomenclature and sequence are those of the system of
classification of Emil Boudier5. Valuable assistance for
correlation of the names with those in Massee's6 book is available
in Dr. Ramsbottom's list of British species7.
