IOI 
A NOTE ON TRAMETES RUBESCENS. 
By W. B. Allen. 
With Plate 16. 
In August and September, 1900, there occurred on Sa/ir 
caprea at Willey, Shropshire, a Trametes which is perhaps 
worthy of a note. 
On the first occasion that it was noticed the specimens were 
immature, being roundish irregular masses oozing out of the 
wood. The pilei varied from whitish to olive-brown in colour 
and were characterized by a dense pulverulence so that, when 
touched, every finger-mark remained imprinted. 
On later inspection the fungus became dimidiate with a very 
decurrent base, the pileus became zoned and the pores were 
seen to be white and the orifices roundish becoming elongated 
and daedaliform in age, especially towards the margin. 
_ The striking feature about the fungus, which could not fail to 
mmediately arrest attention, was that the pores and flesh at once 
changed, on being scratched, from white to a beautiful crimson- 
lake colour, in some specimens almost to blood-red. On being 
dried, the whole hymenium naturally changed to a pinky-tan. 
In our English handbooks there appeared to be nothing at 
all near to it except L7vametes Bulliardi, which is a fungus we 
have often gathered, but never saw it change to crimson on 
~ng wounded: further Bulliard: is a_sweet-scented species, 
whereas this was entirely odourless. On referrmg to Fries’ 
ymenomycetes Europaei we found that he mentioned a 
“ametes rubescens which seemed to fit most admirably, the 
chief points in the description being “ ubique rubescens, junior 
abo pruinosa.” 
his species is not in our British Flora, moreover Fries had 
Not seen it growing, and adds a note that it seems to be close to 
Bulliardi. In his description of this latter he Says “poris e 
pallido, tufescentibus.” This phrasing would seem to imply 
that the colour-change is a gradual process in course of age and 
in drying and is not the usual formula he employs when describ- 
ing a fungus that changes instantly on being wounded. 
Ow rufescens is one of the words not fully dealt with by 
either Canon du Port or Mr. Wharton in their excellent papers 
°n colours of fungi as used by Fries, but we can scarcely recon-
