On the basis of our molecular phylogenetic results we propose that specific
and infraspecific epithets currently placed in the segregate genus Cladina
be transferred to the genus Cladonia, and that Cladina become a synonym of
Cladonia. Of the almost fifty species and infraspecific taxa currently rec
ognized as accepted names, we have identified 14 epithets at specific or in
fraspecific ranks that require transfer into the genus Cladonia. Of these,
eight have never been placed in the genus and six have not been recognized
at their proposed rank or position in Cladonia. In addition, the author cit
ation of the name Cladina mills is corrected.
