Abstract: Cintractiella

             is an unusual genus of smut fungi containing two described species that produce sori as adventitious gall-like spikelets on members of tribe
             Hypolytreae
             (subfam. Mapanioideae, Cyperaceae). In September 200, during a botanical expedition on the volcanic island of Kosrae located in the eastern Caroline Islands and within the Federated States of Micronesia, a specimen of
             Mapaniapacifica
             was collected displaying
             Cintractiella
             -like sori in adventitious spikelets on the host leaves. Sori were hypophyllous, occurring in groups of spikelets composed of olivaceous-brown scale-like leaves, 1–1.5 mm wide and up to 6 mm long. Microscopic comparison with the protologue and drawings of the type material of
             C.lamii
             show several differences in teliospore and sori characters between it and the newly collected material on
             Mapania
             . To our knowledge, this represents only the second known collection of any member of
             Cintractiella
             on vegetative organs of
             Hypolytreae
             and a third species for this genus and the only known smut species infecting
             Mapania
             , herein described as
             Cintractiellakosraensis
             sp. nov.
