Yorkshire Naturalists in Eskdale. 
siderable amount of interest in them was taken by the assembled 
naturalists as well as by other visitors and residents. This 
interest was also extended to the portfolios of Fungus photo- 
graphs exhibited by the writer. 
With regard to parasitic fungi, one specimen only, of 
Polyporus hirsutus was observed, upon Ash, while neither the 
Birch polypore ( Polyporus betulinus) nor Armillaria mcllea 
were recorded. The Larch canker Dasyscypha calycina was 
seen but once, while the canker which is so ruinous to Ash was 
found to be particularly prevalent at Falling Force. Whether 
the last named is the result of fungus or insect attack, or a 
combination of both, has not yet been decided. 
Our chief find undoubtedly was that of some very fine 
specimens of Collybia radicata, on a stump at Falling Force 
Wood. The pilei, which were of a rich brown colour — rugose 
and viscid, were 4 inches and 5 inches in diameter with stems 
of 10 inches and 11 inches in length. Their outstanding 
feature, however, was that the margins of the gills were found 
to be coloured like the pileus while gills of typical specimens 
are wholly white. 
These specimens were sent to our veteran worker Mr. Charles 
Crossland of Halifax, who writes as follows : — ‘ I have carefully 
examined the Agaric but cannot make it other than Collybia 
radicata. The colour of the pileus is certainly deeper than 
usual, and runs along the gill margins almost to the stem, but 
this may be so only in luxuriantly grown specimens (yet there 
is one not particularly luxuriant) ; the others are the finest I 
ever saw. I have carefully examined the gills and find the 
brown cast is due to a luxuriant outgrowth of hyphae, ending 
in clavate or subglobose tips, hyaline in a through light, but 
decidedly with a brown tint in bulk. You are quite right in 
saying that brown gill edges are not mentioned in the books 
as a character.’ 
Mr. A. Clarke, of Huddersfield who later saw the specimens 
says. ‘ Collybia radicata without a doubt — the edges of the 
gills being tinted is probably due to decomposition having set 
in — it is of no value as a character.’ 
I ought to explain that I noted the new feature immediately 
upon gathering the specimens and looked for symptoms of decay 
but had no hesitation in deciding that they were in perfect 
condition and one or more were probably not fully developed. 
Thus is created an interesting position which one feels 
should be the subject of further investigation. Mr. Crossland 
kindly named several other specimens which were sent to him. 
The list includes 132 species of which 66 do not occur in 
the 1902 list. Four are new to the County, viz. — Lactarius 
retisporus Mass., Inocybe maritima Fr., I. margarispora Berk, 
and Boletus cestivalis Fr.
