Intimately related to Z. badia, from Avbich it differs chiefly in tbe form
ami size of the spores, Avhence Nylander I. c. is inclined to regard it as
speciKcally distinct. The specimens gatliered are well fertile, with tlie
apotliecia nmuerou.s, crowded, at times 2-3 confluent. As previously
observed (p. 85), it is one of the hosts of Sjfhinctrina kylemoriensis.

In general appearance suhsimilar to Lecidea kochiana, but separated by
the lecanorine apothecia. These, according to Fries (Lich. Europ. p. 147),
are at times obsoletely pruinose, a character not apparent in the two
British specimens seen.

I he Ihallus spreads very extensively and varies somewhat in thickness
and colour.^ In some other countries it occurs on the trunks of ai>-ed
trees,^ but it has not with certainty beeu found upon such in Great
Jsntain ; though what may be the sterile thallus has been noticed spar-
mgly on oaks m tbe New Forest. The apotliecia are numerous, though
somewhat scattered, with the thalline margin often obliterated. The
spermogones, which are very minute, scattered, and slightly prominent,
might readily be mtstaken for very young apothecia, with which they are
concolorous. » i / j

Distinguished by the less pulverulent, constantly whitish thallus and
by the darker biatoroid apothecia. I t seems a distinct variety rather than
a state of the^ so-called variety porphyria (Pers.), into which the type
passes in certain situations.
