Chordaria in family characteristics is close. In case Rupr&chtiella
fUiformis (Rupr.) Yendo (Trav. Mus. l'Acad. Imp. Sci. St. Petersb.,
vol. 10, l!n.'!. p. 118) proves to be identical, generic-ally at least, with
Anal ipus fusiform is Kjellm., Analipits must be removed to the Hetero-
chordariaceae.
36. Gobia Reinke
Frond filiform, more or less lubricous, simple or branched, hollow
except in the very young stage, growth apical or subapical, composed
of an inner tissue of loosely anastomosing colorless filaments giving
rise to short, compact, vertical, assimilating filaments, to zoosporangia
and to scattered colorless hairs; gametangia unknown.
Reinke, Algenfl. westl. Ostsee, 1889a;, p. 65.
The type of the genus, and the only other species known except the
following, is Gobia. baltica, based upon material of Cladosiphon
balticus Gobi (Brauntange finn. Meerbus., 1874, p. 12).
The growth in length of the species of Gobia is said to be from an
apical cell at first, but this soon ceases and intercalary growth sets in
(cf. Reinke, 1889a, pp. 65, 66). If we are correct in referring the
Mesogloia simplex Saunders to Reinke 's genus Gobia, with which it
seems to agree in details of structure, we are probably also correct in
interpreting the growth of the genus as being subapical in that the
apical cell in very young plants and in very young branch initials very
early cuts off a subapical cell which takes on the principal meristematic
function. The same thing happens in Chordaria and presumably also
in Myelophycus and in AnaUpus. This is very different from the
situation in Dictyosiphon, where the terminal cell retains its meris-
tematic function and activity as long as active growth in length con-
tinues. Gobia, from this point of view, differs from the other genera
of the Chordariaeeae in the loosely placed anastomosing filaments of
its inner tissues.
Gobia simplex (Saunders) S. and G.
Plate 42, fig. 58, and plate 78b
Fronds olive brown, 5-12 cm. high, 2-3.5 mm. diam., simple, cylin-
drical or in part decidedly clavate, often arcuate, very blunt, solid in
the juvenile stage, soon becoming hollow except at the very base of the
apex, attached by a small disk ; central filaments loose, colorless, ana-
stomosing freely, 25-35/* diam. ; cortical filaments straight, perpendi-
cular to the main axis, the terminal segments composed of 2-4 cells.
