A study on the mangrove leaf litter fungi of two tropical
mangroves in Singapore was carried out. Five Halophytophthora
species and four isolates which did not fit the descriptions of known
species were isolated from leaves of Avicennia alba, A. rumphiana,
Rhizophora apiculata and R. mucronata. Halophytophthora
exoprolifera, H. kandeliae, H. operculata, H. spinosa var.
lobata and H. vesicula are new records for
Singapore; the first three also being new records for tropical
mangroves. The isolate of H. exoprolifera sporulated at 28
°C and may be a tropical strain. H. operculata is
reported for the first time outside of Australia. The results of this
study contribute to the little known distribution of the
Halophytophthora in the Indian Pacific region. Thirteen
deuteromycetes were also isolated from the mangrove leaf litter and
represented both phylloplane fungi as well as possible marine
fungi.
