the Highlands, about Aviemore, and elsewhere.—I t has been found in
England, near Twizel House, by P rideaux J ohn S elby, Esq. and by
myself in the grounds o f Morton J ohn D avison, Esq. of Beamish, near
Newcastle.
Plant effused, in distinct roundish patches, or confluent, not immersed in
the leaf in the slightest degree, whitish when young, changing gradually
to orange, reddish-brown, and lastly very rich deep brown. Peridia
polymorphous, rarely simple, b u t for the most p a rt terminated b y
several short, obtuse processes ; the main summit is often truncate.
A fine species, intermediate between tbose with simple,
and those with branched peridia, exactly analogous to tbe situation
of Clavaria rugosa.
