The dense clusters it forms, are frequently composed of several
hundred plants, and the stems, which accommodate themselves
in length and direction to their situation, are so crowded and
compressed at their base, as to appear more or less united in
bundles, whence the origin of the specific name. In general
habit, this species resembles A. velutipes, a plant confined to
the same kind of station; and still more nearly A. lateritius, a
very distinct species, to which A . pomposus of B o l t o n must
be referred.
The sporidia of A . fascicularis are of a dark colour, and
are shed so copiously, as to discolour all the pilei situated beneath
the rest.
