Molecular Taxonomy:

Tan and Druehl 1994; Tan and Druehl 1993

Life History:

alternation of heteromorphic phases, with macroscopic sporophytes and microscopic discoid gametophytes that initially may be filamentous; isogametes produced from surface cells, unfused gametes recycling the gametophytic phase (Wynne 1969a, p. 14)

Phenology:

annual sporophytes appearing in the spring and summer, becoming fertile sooner in the south than in the north
