Seventeen seaweed species (two green algae, nine brown algae and six red algae) of the Andaman Islands, India, were studied for their culturable fungal endophyte as-semblage. A total of 796 endophytic isolates (67 species of fungi belonging to 22 genera and 10 sterile forms) were recovered from the 17 seaweeds. All the fungi were marine-derived forms and many belonged to Eurotio-mycetes and Sordariomycetes of the Ascomycota group. More species of Aspergillus, Fusarium, Penicillium and Trichoderma were present as endophytes. While most endophytic species recovered were present in low fre-quency, some fungi like Aspergillus niger, Aspergillus sp. 1, Nodulisporium sp., Pestalotiopsis sp., Trichoderma yunnanense and Xylaria sp. 1 exhibited more than 40% frequency of colonization. Apart from yielding the maxi-mum number of endophytic isolates, different Tricho-derma species showed the highest colonization frequency in 11 of the 17 seaweeds. The results of this study indi-cate that fungi belonging to Eurotiomycetes which occur in low frequency as endophytes in terrestrial plants represent a significant percentage in the seaweeds and that the environment might have a more critical role than host specificity in determining the endophyte commu-nity of seaweed mycobiome.
