In a new type of Batrachospermum life history, the Batrachospermum phase does not originate from the erect filaments of a Pseudochantransia but directly from a prostrate crustose growth, the prothalle of Sirodot. It is probable that the few lowermost segments of those Batrachospermum cladomes are diploid, the remainder due to an interposed “somatic” meiosis are haploid.
