Myriactula pulvinata   (Kutzing) Kuntze,  1898 (Algae)
Organism information awaits expert curation
Class: Phaeophyceae

Plants forming small, globular gelatinous tufts. Basal endophytic portion forming the medulla and upper peripheral portion forming the photosynthetic cortex. Basal part of the medulla consisting of hyaline rhizoidal cells, irregular in shape; 10-13 µ long and 6-15 µ broad. Upper part of the medulla composed by short branched filaments of chained, moniliform, hyaline cells 33-150 µ long and 16-40 µ broad. Cortex composed of assimilatory filaments and hairs, as well as reproductive bodies interspersed among them. Assimilatory filaments narrow at the base, broad above, 150-200 µ long and 12-16 µ broad. Hairs long, tapering gradually towards the apices. Intercalary meristem situated at the bases of the assimilators and hairs.

Plants asexual, bearing both unilocular and plurilocular sporangia, arising from the apical cells of the medulla or from near the bases of the assimilatory filaments. Unilocular sporangia pear-shaped, 82-198 µ long and 26-36 µ broad. Plurilocular sporangia cylindrical, uniseriate, 132-190 µ long and 6 µ broad.

Epiphytic on Cystoseira.
