almost entirely furliiraceous, with a few scattered squamules towards
the base. Tbe apothecia, which are small, dark-brown, are verv rarelv

both, however, it is separated by the podetia and the reaction with K,
so th at It may with propriety be regarded as holding an intermediate
specilic place, lu our British specimens there are only a few youno-

Well distinguished by tbe minutely foliaceo-squamulose podetia (wbioli
in old age become siibdemidate) and by tlieir perforate axils with dentate
or sublacerate margins. Tlie podetia vary in height from 1 to 3 inches,
aud are slender or somewhat turgid, simple or repeatedly branched. It
is not very common in fruit, but when present the apothecia are cymoso-
aggregate, at first plane and margined, at length convex and immarginate.

Probably this is to be regarded as but a more robust state of the type
(with which it is sometimes confluent) depending upon the nature of tbe
habitat. Tbe podetia are nmcli branched, with the branches often as if
