The apothecia, frequent in the single specimen seen, often appear
as if divided into several hymenia. The spermogones, sparingly
present, have the spermatia cylindrical, or fusiform-cylindrioai,
0,004-/ mm. long, 0,0008 mm. thick.

Stirton remarks th a t this species is nearly allied, if not identical
with A subumbonata, but the larger apothecia and spores seem to
make it distmct.

specimen in the British Museum, collected by W. Johnson at Bywell,
Northumberland, and labelled by him L. contortula, has no visible
thallus, and the apothecia are not gyrose ; but the spores and other
characters agree with the description given.

Closely allied to the following species, from which it differs in the
more contiguous, at times subrugose thallus and in the more concave
, immersed apothecia. In the original specimen cephalodia are absent
as IS usually the case in Britain.
