NOTES ON SOME OF THE EAKEIi 
FUNGI 
FOUND IN 
OK NEAR MATTISHALL IN 1880. 
By Rev. J. M. Du Fort. 
Read 2,0th Nov., i88o. 
Agaricus (hebeloma) osterosporns, a new species, described and 
named by Dr. (^uelet in 1879, groAvs very plentifully in a mixed 
Avood of beech and oak at Mattishall. It is someAvhat like Agaricus 
riinosus, but the colour of the stem, and tlie peculiar shap>e of its 
bulbous base, besides the stellate form of the spores, mark it very 
distinctly. I had previously been puzzled by it because of these 
characteristics, Avhich distinguish it from Agaricus rhnosus. 
Russula fellea, Avhich had not been recognized in the British 
Isles till last year, groAvs freely in the same Avood, and on the 
Western Broad Avay betAveen Honingham and Weston. Many 
species of Russulce arc not very easily distinguished from each 
other, but the straAV-colourcd stem, and the arrangement of the 
gills, clearly separate this species from Russula ochroleuca. 
On November 12th I found a Polyporus in this same Avood, 
Avhich Mr. PloAvright pronounced to be Polyporus picipes, an 
uncommoir species. 
A Lactarius, found on August 12th at Mattishall Bergh, somc- 
Avhat like Lactarius torminosus, after comparison Avith a specimen 
sent by Mr. Rcnny from fSwitzerland, seems most probably to be 
Lactarius scrohiculatus. I hope to find another specimen of the 
plant next year, Avhich may decide the name, as this species has 
not yet been noticed in England. 
In the last Aveek of September some SAvede Turnips at Mattishall 
Avere affected Avith Avhat seemed to be a prodigious quantity of 
Peronospora parasitica. On closer examination this Avas seen to 
be a noAV disease among Turnips, Oidiuin balsamii, figured and 
described by Mr. Worthington Smith in the ‘ Gardener’s Chronicle’ 
for 25th September, 1880. Though the leaves Averc covered Avith 
the fungus, the roots did not seem to liavc suffered mucli. This 
fungus had only been found before on IMullcins and StraAvberry 
plants.
