F o UN D on rocks, as well as on trees in old dark woods,
but only in the alpine counties. We have gathered it about
Amblefide, Weftmoreland, and at Hafod, Cardiganthire.
Mr. E. Forfter found it in Rookwood grove, at Boconnoc,
Cornwall, and Dillenius, Mr. Griffith and Mr. D. Turner in
North Wales.
The fronds fpread from a centre in a loofely imbricated
manner among mofs, generally on the trunks of trees, efpe-
pially hazels and thorns. Their texture is membranous and
pliable ; their lobes rounded, various in fize ; their upper fide
rather rugofe, of a greyifh or greenith brown, fprinkled all
over with rough, dark-coloured warts or granulation?; their
under fide pale reddiffi brown, downy, dotted with fmall,
white, fmooth, fcattered pits. The ffiields are of very rare
occurrence, Handing for the möft part near the margin, fmall,
llightly elevated, having a rufty-brown difc, elevated by age,
and a narrow, pale, entire border, which is obliterated as the
ffiields grow old.-----Hi is has been confounded with L .ß l -
vaticus, with which it agrees in a certain foetid fmell when
moift, and fomewhat in colour; but differs widely in fructification,
as well as in the fize and roundnefs of the lobes.
