Material examined. SAM H2339, preserved colony; two microslides ( SAM H2579, H2580). PIRSA Stn IBMP 2c.

Description. One colony or several fragmented infertile colonies without hydrorhizae. Stems irregularly branched at angle of 60–80°, branches robust, monosiphonic, internodes more or less cylindrical, increasing slightly in width distally beside hydrotheca, oblique node just above axillar hydrotheca as a strong indentation in perisarc.

Hydrothecae biseriate, short, conical, narrowing from floor to margin, one almost distal on internode, perisarc smooth to weakly undulated, free adcauline wall straight to slightly concave, fixed adcauline wall convex, abcauline wall almost straight to weakly concave, ratio of adnate adcauline wall to free adcauline wall 1.8:2.4. Floor transverse. Margin with four low equidistant cusps, some margins with one or two replications.

Colour (preserved material) pale honey yellow; perisarc thick throughout.
