Abstract
Several fungal parasites of marine algae from Mandapam, on the east coast of south India, are reported. The green algae Chaetomorpha media (C. Agardh) Kutzing collected from intertidal rocks showed the presence of the fungal parasites Pontisma lagenidioides Petersen and Labyrinthula sp. on incubation in sterile seawater under laboratory conditions. Whole plants were destroyed within 12 to 15 d. Similarly, the blue-green alga Lyngbya sp. and the green filamentous algae Rhizoclonium sp. and Cladophora sp., incubation in seawater, showed severe infection by Labyrinthula sp. The host range of Labyrinthula sp. and culturing methods are also discussed. These pathogens are new records from India and some of the host/parasite combinations reported here are also new. Species of Cladophora showed infection by Sirolpidium bryopsidis (de Bruyne) H. E. Petersen and Olipidium rostriferum Tokunaga. An epiphytic chytrid on the brown alga Sphacelaria sp. was identified as Chytridium polysiphoniae Cohn.
