H ab. Between the scales of old half-decayed cones of Pinus Abies. Appin,
Captain C a rm ic h a e l.
Plant produced within the scales of the cones, aggregated, crowded, sub-
globose, of a reddish-brown colour. Sporidia oval, of a dull pale yellow,
copious, enclosing sporidiola. The peridia are apt to hu rst somewhat
irregularly at first, b u t eventually are so far transversely divided
as to leave the lower half, which remains for a long time after the sporidia
have escaped.
This rare and fine species has been added to the British
Flora by my indefatigable friend Captain C a r m i c h a e l , who
finds it at Appin, on the west coast of Scotland. It is considered
as of unfrequent occurrence, even on the Continent.
A l b e r t i n i and S c h w e i n i t z were the first to describe it.
