Mitosporic fungi isolated from seagrasses in the northern Gulf Coast of the United States.

Fungi are known to be species rich and important as decomposing agents for a number of coastal and estuarine plants, such as marshes and mangroves. The reported number of marine fungi associated with seagrass beds is relatively lower, and their role in such plant communities remains to be examined in greater depth. Monthly sampling in seagrass beds composed of Thalassia testudinum and Halodule wrightii in the Perdido Bay, FL. area has resulted in the observation of previously reported fungi, but also some new interesting fungi. This is the case of the conidial ascomycetes Trichocladium allopalonellum and Cumulospora marina, which constitute new reports on seagrass substrates. Additionally, Trichocladium achrasporum appears to be a new record for Ruppia maritima. Other fungi isolated are Dendryphiella arenaria, previously reported from T. testudinum, and one unidentified species of Phoma. All of these fungi were isolated from surface sterilized blade fragments placed on nutrient agar. The most commonly isolated fungus was Trichocladium allopalonellum. Detection of these fungi on standing leaves of seagrasses, helps support the notion that filamentous mitosporic fungi are more diverse and common, and their ecological role in seagrass beds more significant, than previously reported.
