This species is represented by a single gathering in July 1868 1 Thwaites from Ceylon. The sporangia are to a large extent immatui purplish, and with the spores imperfectly developed, but a few a nearly mature and show the rufous-brown colour described abov Although the character of the long clustered stalks is peculiar, tl colour and texture of the sporangium-wall, and the colour, size, ai markings of the spores are similar to what is ^en in other membe of the TubulinecB, while the threads of the capillitium find a clo analogy in the tubular extensions of the sporangium-wall of Siph ptycMum.
