A new species of Cintractiella (Ustilaginales) from the volcanic island of Kosrae, Caroline Islands, Micronesia.

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 an
