lias very much the asqiect of Cladonia gnmgens, from which, as well
as from an analogous form (tenuis Floerke) of C. rangiferina, not yet
detected iu Britain, it differs in the absence of anj' reaction with K. It
is from 1 to 14 iu. high, and with us occurs only sterile.

distinguish this form. Tlie apothecia are rare.

brandies. Altliougli regarded by some authors as a distinct species s. n.
Cladonia urhuscida AA’allr., it bolds only a somewhat analogous relation
to the type as forma gigantea does to the preceding species. I t varies in
leiigtli from 3 to 5 in., and occasionally has the podetia very robust and
less branched. The few British specimens are only sparingly fertile.

this. Apparently, however, it is only an abnormal aud stunted condition
of the preceding variety. I t is very rarely fertile.

A well-marked variety, wbicb alike in a young and mature state
appears to be constant to its characters. I t is ea-ily recognized by the
densely thyrsoid apices of the podetia, which are usually shorter than in
the type. With us it is very seldom fertile.

The much smaller size (1-2 in. high) and the cæspitose pulvinate habit
distinguish this form. I t approaches states of Cladonia pungens, from
which the absence of any reaction with K keeps it distinct. I t rarely
occurs in a fertile condition.
