Abstract

Roots of coffee and rubber plants and four ferns growing along two streams were examined for the presence of endophytic aquatic hyphomycetes by plating and aerating surface-sterilized root segments. No aquatic hyphomycete colonies could be isolated from plated root segments. Aeration yielded conidia belonging to 5-8 different aquatic hyphomycete species per plant. Average conidial production ranged between 3 and 410 per g root mass in five of the plants; in the fern Christela dentata, it reached 12,900. Between 8 (decorticated roots of Coffea arabica) and 96% (entire roots of C. dentata) of root segments yielded aquatic hyphomycete conidia. The number of endophytic aquatic hyphomycetes species amounted to 14 and 38% of the total species numbers previously found in the two streams. Tetracladium furcatum. Triscelophorus acuminatus, T. konajensis and T. monosporus are recorded for the first time as root endophytes.
