N o t uncommon on trunks of trees, old pales, large Hones,
and barren fandy moors, frequently growing llightly attached
to the Items of heath, and very confpicuous from its bleached
white colour, and its elegantly divided and curled form, but
the Ihields are very rarely indeed to be found. Our fpecimen
was gathered on Cromford Moor, near Matlock, by Dr. Smith,
who is poffefled of another from Malvern Hills, Worcefterlhire,
in which (contrary to the remark of Dillenius) the powdery
terminations (1) and the Ihields (2) are on the fame individual
plant. This powdery part, which Dr. Hedwig confiders as the
male flower, is frequently feen, though the Ihields are fo very
rare that we could hardly prefent the reader with a greater bo-,
tanical curiofity. We are therefore inclined, from this circum*
fiance, and from the analogy of L. ciliaris (fee With. V. 3. 30)
to think the black warts (3) are rather the male flowers.
This fpecies is remarkable for being always compofed of two
membranes, the undermoft black, the upper white, with a con-,
fiderable cavity between them. Sometimes the plant grows out
into large cylindrical powdery protuberances, which are like*
wife hollow. Our figure reprefents a group of different individuals
in various dates, not all from one root.
Dillenius, in his quotation of Linn, pi, Lapp, confounds this
yyifh L. centrifugus.
