Balmuto, Fifeshire— In England it has been found by S o w e r b y at Walthamstow,
and Kensington Gardens; near Darlington by Mr R o b s o n ;
also at Allesly by the Reverend Mr B r e e .
Whole plant 2 - 4 inches long, whitish, extremely slender, filiform, smooth,
more or less attenuated at the apex, flexuose or straight, the hymenium
gradually passing into the stipes, which is generally minutely tomentose
or strigose at the base. Radicular tuber dark brown, compressed, roundish,
as large sometimes as the seed of a common vetch.
In the 1st volume of this work, I have figured one species
of Pliücorhiza, and have explained iny reasons for extending
the genus to all those Clavarim which possess a radicular tuber.
