Semicells in frontal view suboblong with broadly rounded angles and convex lateral sides. Lateral sides, including the apical angles, 5–6-crenate, the crenations near the basal angle with one granule, the other ones generally with two granules. Apex truncate and bi-undulate. Cell wall ornamented with small granules, arranged in short, intramarginal, radiating series, the upper 4–5 lateral series doubled near the margin. In addition, a central tumour ornamented with 6 bended vertical series of granules, the inner two as a rule mutually fused to a big, central wrath. Semicells in apical view broadly elliptic with a more or less triangular tumour on either side, in lateral view subovate with a faint inflation near the base. Chloroplast axile with one pyrenoid. Zygospore globose, furnished with long, stout, furcate spines.</paragraph>
