Fossombronia longiseta

Distinguishing Features

Often obscured by other bryophytes and small grasses on seeping open soils or protected under south-facing rock overhangs, this translucent and frilly green occasional liverwort forms lettuce-like patches (~3-10 mm wide) of sinuous and continuous leaves. Functionally annuals, plants of F. longiseta are so named for the short-lived but tall (up to 3cm), sprout-like sporophyte that emerges in spring. Microscopic examination of the spores are required for identification.
