Investigations on the genus Phycopeltis (Trentepohliaceae, Chlorophyta) from South-East Asia, including the description of two new species

In the course of an investigation of the genus Phycopeltis from South-East Asia, two new species, P. javanica and P. juarensis, were discovered; P arundinacea and P. dorsopapillosa were also recorded. P. javanica is characterised by obligate alternation of generations, intercalary gametangia and zoosporangia, absence of a sporangiophore and presence of dorsal papillae. P. juarensis is characterised by obligate alternation of generations, intercalary gametangia, terminal zoosporangia and presence of a sporangiophore up to five cells long. For P. dorsopapillosa the present record is the first for South-East Asia, suggesting the possible pantropical distribution of the species.
