RECEPTACLE (r) 190-640 µm slender or stout, variable in shape and size, with a dark-coloured foot (f) and one, two or rarely more lateral projections of receptacle stalk cell II (rscII); in very young thalli, the receptacle consists of a series cells continuing into a filiform primary appendage; later, except for the large basal cell, all the other cells divide again to form a small-celled tissue. The expanding cup-shaped distal cavity is 120-260 µm diam and has many filiform, multi-celled appendages (app), up to 580 µm long, on its margin; on the inner surface of the cavity, perithecia (p) and antheridial branchlets are present.
