This differs from the type in tlie upper portion or the entire length of
the stipes being concolorous with the underside of the eapitulum. It
is probably an accidental state. Leighton erroneously describes it as
liaving a whitish margin.

The tliallus, even when best developed, forms only a very thin, widely
spreading film, which often becomes obliterated. The minute, scattered
apothecia, the slender stipes, the form of the capitulum, the rather compact
mazædium, and the simple spores distinguish it from its British
allies.

This differs from the type in the colour of the thallus, the constantly
minute apotheoia, and the colour of the underside of the capitulum. In
the only British specimen this last character is scarcely apparent.
