Morphological variation ofStromatella monostromatica

Abstract

Thirty two isolates of Stromatefla monostromatica (Dangeard) Kornmann were studied in unialgal culture; extensive morphological variation was documented. The shape of bicellular germlings and development of young plants were similar for all isolates which had globular sporangia. These features are, therefore, the most important diagnostic characteristics of the species.The widespread distribution of S. monostromatica suggests that this is a cosmopohtan species.
