Cystocarp development in the red alga Nothogenia fastigiata (Galaxauraceae, Nemaliales)

Cystocarp development in the red alga (Galaxauraceae, Rhodophyta) Nothogenia fastigiata (Bory) Parkinson (the type of the genus) was examined in detail. Carpogonial branches are typically three cells in length, with the hypogynous cell producing 3–4 sterile branches and the basal cell producing a similar number of branches that will eventually form the pericarp. Following fertilization, the gonimoblast arises directly from the carpogonium and grows laterally, eventually lining the pericarp and producing terminal carposporangia directed towards the centre of the cystocarpic cavity. The production of the gonimoblast directly from the carpogonium is entirely compatible with the placement of Nothogenia in the order Nemaliales.
