From P saltata it is distinguished not only by the larger thallus and

This approaches P. rufescens, hut is distinguished hy the numerously
lobed thallus with its glabrous and shining- upper surface, and by the
form of tlie smaller apothecia. These are usually abundant, adnate or
elono ate and attenuate lobes, and at length become revolute. Sometimes
they occur two together (geminate) on each fertile lobe, m which state
it is represented iu Dill. I. c. {J'eltidea pellucula Ach.). On the margins
of the lobes pycnides occasionally occur, w ith stylospores oblong, oblongo-
fusiform or almost ovoid, 0,007-0,012 mm. long, 0,003-4 mm. thick. ^
