The moss-back alga (Cladophorophyceae, Chlorophyta) on two species of freshwater turtles in the Kimberleys

The range of the Australian freshwater alga Basicladia ramulosa Ducker is extended, both in its turtle hosts (Chelodina burrungandjii Thomson et al.; Emydura australis (Grey)) and in geography, to tropical northern Western Australia. Along with further morphological observations, sporangia are described for the first time in this taxon.
