F ir s t observed on the Scottish mountains by Mr. Dickson,
Our specimens were gathered by Mr. Turner on the top of
Ben Lawers, and we have received others found on Skiddaw,
Cumberland, by W. Pilkington, Esq., F.L.S. It grows on
dry turfy alpine heaths among mosses. Several stems often
spring from one common small root, and spread horizontally
in every direction. They are snow-white, without any polish,
simple or branched, tubular, round, tapering towards each
extremity, so as to be often very sharp-pointed. They are
somewhat zigzag, and the surface is a little pitted. Dr.
Acharius thinks the fructification is unknown. Mr. Dickson
represents globose lateral tubercles, and we find a similar appearance
on one of Mr. Menzies’s American specimens, rather
resembling the young thick-edged shields of an Acharian
Parmelia. Indeed we cannot but consider this plant as a very
doubtful Bceomyces, for the leaves drawn by Dillenius are
surely a mistake.
