I t is remarkable that this pretty species should have remained
so long undescribed. That it is not very uncommon in
England is certain. We have had it from various friends, as
Dr. Abbot, Mr. W. Brunton junior, Mr. Turner, the Rev.
Mr. Walford of Long Stratton, and the Rev. Mr. Harrima'n.
Neither is it difficult to discover. It grows on old trees,
either on their cracked bark or in their decayed cavities, apparently
not thriving on live wood. The crust is thin, even,
finely leprous, very white (at least when dry), bearing prodigious
abundance of little bright orange-coloured shields, generally
crowded together in parcels or rows. When young
they are flat, with a border coloured like the disk; but by age
they grow very convex and lose their border.
There is a little yellow Peziza found on cow-dung, which
seems confounded with the sculellata, and another on rotten
wood, P. aurea, Soiverby t. 150, which being very common,
and somewhat resembling this Lichen, may have caused it to
be passed over by many observers.
