Original despcription by R. Ruedemann (1947, p. 264):
"Rhabdosome composed of long slender, flexuous conical thecae, forming a bushy colony by repeated and irregular branching. Three of four radial branches of the first order and seven or more of the second order. Rhabdosome reaches diameter of 20 mm or more; single branches 14+ long, and beginning with a width of 0.3 mm attain such of 0.8 mm. Apertures terminal, round, straight transverse. New tubes arise out of circular openings that are irregularly spaced. They are usually inclined forward, at various angles and may also curve backward. Only branches of first and second order have been observed. No sicula, nor any growth lines seen." |
