A peculiar plant having the aspect of some ally of L. mplochs. In 

 the two specimens seen the thallus is rather scattered and little visible, 

 being overrun by a foreigu plant, but the apothecia are frequent.

Usually not rightly separated by authors from L. exuina and L. 

 roboris. The tliallus is generally small, macular, thin, distinctly limited 

 by the hypothallus, rarely thickish and more expanded. It is always well

 mutual pressure.

 tracts. — Distr. Local and scarce in S., W., and N. England, and in S.
