Common reed (Phragmites) interacts with a large suite of other organisms including cryptogams attached to live or dead culm bases. We report an unusual observation of at least ten taxa of lichens and hepatics attached to persistent reed stubble on the swampy bank of freshwater Cypress Creek north of Tampa, Hillsborough County, Florida. This bryoid material included the minute, leafy hepatics Microlejeunea globosa, Microlejeunea cf. ulicina, Myriocoleopsis minutissima, and Frullania cf. inflata; and the lichens Arthonia subdiffusa, Chrysothrix xanthina, Opegrapha viridis, Phaeographis sp., Physcia sp., and an unidentified species of Parmeliaceae. These generally corticolous or epiphyllous taxa have not previously been reported from common reed, and suggest unrecognized complexity in both cryptogamic microhabitats and reed epiphytes.
