We have not yet completed our taxonomic analyses of the Hawaiian
Campanella  species.  Three to four species occur in Alien Wet Forests in the
Hawaiian Islands, differing mainly in microscopic details.  Several discolor greenish
grey to bluish grey in age, while several remain white to buff throughout maturation.
Marasmius hawaiiensis  Henn., described from material collected on Molokai in 1887
and subsequently lost, is probably a Campanella .
