Abstract

MICHETTI, Karina M.; LEONARDI, Patricia I.  and  CACERES, Eduardo J.. Vegetative morphology and asexual reproduction of Draparnaldia mutabilis (Chaetophoraceae, Chlorophyta), first verified record for Argentina. Darwiniana [online]. 2007, vol.45, n.2, pp.175-180. ISSN 0011-6793.

Thalli of Draparnaldia mutabilis consist of a reduced, prostrate rhizoidal system and an erect system with marked differentiation between axial and lateral, highly branched, filaments, grouped in dense fascicles. The asexual reproduction is by zoospores with an erect germination pattern. This is the first verified report of this species for Argentina. In addition, a key to the best-described species is provided.
