Overview
Comprehensive Description
Description
The foliose phase (gametangial) in the life-history grows from a small holdfast and short stipe to form one or more delicate fronds, flattened and thin. Fronds to 30 cms or more in length branching irregularly and from the margins. The tetrasporangial phase is crustose. The tetrasporophyte is crustose and very difficult to distinguish from other encrusting algae. The gametophyte is very similar to Halymenia latifolia and some other red foliose red algae.
