Note on a Fungics found imbedded in th^ Eens of Cambridgeshire, 



By the Eev. M. J. Berkeley, F.L.S. &c. 



[Bead February 5th, 1856.] 



FuKGi are so rare in a fossil state, if indeed any undoubted cases 

 occur before the post-pleioccne period, that no apology need be 

 made for recording so trifling a matter as tlie present. Moulds 

 are occasionally well preserved in amber, and a diligent search 

 would probably detect species of other groups amongst the vege- 

 table relics in the London clay. In the Museum at Kcw there is 

 a specimen of Polyporus famentarius^ Pr., communicated from the 

 Fens of Cambridgeshire by the Eev. Mr. Hailstone, where it 

 occurred with bog-oak, and must have been buried for many 

 centuries. The specimen is so perfect that it shows the peculiar 

 substance of the pileus in admirable condition, both as regards 

 colour and texture. It may be remarked, that the specimen, which 

 is attached by the centre and ungulate, is far more strongly lac- 

 cate than any British individuals which have passed through my 

 . hands, and in fact accords perfectly with one which was gathered 

 in Sikkim by Dr. Hooker, and which may be seen in the same 

 compartment of the Museum. It must have been dependent from 

 Bome large branch, a situation in which the species seldom if ever 

 occurs in Great Britain, and was probably surrounded by a moister 

 atmosphere, in consequence of the prevalence of extensive forests, 

 than exists at present in the same or neighbouring districts.
