with species of Clavulina on GenBank, thereby corroborating
our initial generic assignments based on morphology. The
maximum parsimony (MP) analysis was based on 787 bp of
rpb2, utilized 263 parsimony informative characters, and
yielded four most parsimonious trees of 1112 steps. Each of
these trees supported the placement of the four species in
a monophyletic Clavulina, within a broad assemblage of neo-
tropical species. The ML analysis produced a phylogeny with
a likelihood score of ln 5410.20416, with similar overall topol-
ogy to the MP trees (results not shown). One of the four most
parsimonious MP trees is illustrated in Fig 1, with MP and
ML node support generated from 1000 replicates. Based on
this phylogeny, the four Clavulina species described here occur
in a monophyletic Clavulina at various positions within a neo-
tropical assemblage and are not closely related to north-tem-
perate taxa.
