The Fungus Flora of the Mulgrave District. 63 
leaves, etc., in the early part of the year. One hundred and 
seventy-three species were finally determined, about fifty 
being additions to previous lists. 
At the September foray five agarics not previously recorded 
for the British Isles were found. Three of the five were 
figured by Miss Massee on Plate I. of The Naturalist for 
January. These was also a beautiful little greenish Mycena — 
M . chlorantha. Of the 392 found, fifty-seven were still further 
additions to the district, making 107 for the year, thirty-four 
being new to Yorkshire, ten of which were new to Britain. 
(See The Naturalist, January 19x3, pp. 21-28, with Plate.) 
In 1913 two meetings were again held. Twenty-seven 
further species were added to the district records in May, and 
sixty-one in September. Thirty were new to Yorkshire, two 
being new to Britain (See The Naturalist, Jan., 1914, p. 12). 
Prior to the publication of the Yorkshire Fungus Flora in 
1905, it was impossible to tell which were new to Yorkshire. 
The appearance of that work put the county records on a 
proper basis, and made it an easy matter to keep them periodi- 
cally posted iix The Naturalist, where they may be followed. 
At and since the foray of 1908 no fewer than 166 Mulgrave 
finds have proved to be new to Yorkshire, to which may be 
added one found in 1894 and four in 1900, making 171. Of 
these thirty-three were new to Britain, two being new to 
science. 
There must be many widely-spread species certain to be 
there which we have not yet seen, especially micro-species. 
The grounds at Kew, of about 300 acres only, have yielded 
over 2,200 species. If it was possible to carefully investigate 
all suitable spots at various times of the year, the known 
mycological flora could still be very considerably increased. 
A glance at the table shows that we are comparatively weak 
in some branches, especially the Ascomycetes, considering the 
great number of known British species. Nor are either the 
Deuteromycetes or the Hyphomycetes at all well represented. 
So far as we have found, under thirty are parasitic on the 
trees ; under fifty on herbaceous plants and other fungi ; and 
three or four on insects. The rest live as saprophites on dead 
and disintegrating vegetable substances, which they help very 
largely to break down and reduce to humus. These ancient 
and charming woods, situated near the sea, and intersected 
by streams, are to some extent independent of weather con- 
ditions, so far as moisture is concerned. 
These bring the total revised and corrected number regis- 
tered for the Lythe-Mulgrave-Sandsend district to about 1245. 
Numerous varieties have been recorded, but none taken into 
account in these calculations. The records have accumulated 
as follow : —
