H ab. On the inferior surface of the leaves of the Beech (Fagus sylvatica),
in summer. Frequent.
Plant forming mostly distinct spots on the under surface of the leaves,
sometimes confluent, minute, granulose, densely crowded, slightly immersed
in a hollow of the leaf ; when young whitish, at length purplish
and rich brown. Peridia davate, and more or less turbinate.
A beautiful carmine-purple variety of this species occurs on
the Continent, and especially in Switzerland, and is mentioned
by D e C a n d o l l e , P e r s o o n , and K u n z e . The ordinary
state of it has been recently discovered in various parts of England
; and I have noticed it in many places in Scotland. Mr
B a x t e r of Oxford communicated fine specimens to me last
year (1825).
