T_PLHIS grows on the ground in heathy mountainous places.
We have gathered it near Edinburgh, bearing tubercles, which
Dillenius says are rarely seen.
It is considered by Acharius as so near the common L. pyxidatus,
t. 1393, that he doubts whether, it be more than a variety.
The same question may arise concerning many of this
tribe, but this appears to us as distinct from pyxidatus as most
others. The neat elegant slenderness, and white colour, of the
stalks, are characteristic, and the sharp triangular teeth, which
border the cups, are peculiar. The tubercles also are very
different, being always minute, reddish brown, at the end of
each tooth. The margin is occasionally proliferous, and in
some of the younger cups the tubercles are almost confluent
and sessile, but each seems to become subsequently elevated.
