The blades of Calliblepharis jubata may vary in width and the degree of subdivision. In Cornwall and the Isles of Scilly specimens occur that are unlike the normally accepted appearance, these have particularly broad fronds up to 15 mm long (Dixon & Irvine, 1977). Calliblepharis jubata is very similar to Calliblepharis ciliata. However, the latter has smaller branchlets (5 mm) and a wider frond. Calliblepharis jubata matures in summer, with the appearance of cystoscarps and spermatangia. Calliblepharis ciliata mature throughout the winter (Dixon & Irvine, 1977).Specimens of Calliblepharis jubata with narrow blades may also be confused with Gigartina acicularis. However, Gigartina acicularis is a rigid plant that reaches maturity in winter, while Calliblepharis jubata is not rigid. Very young Calliblepharis jubata may also resemble Gelidium spp. However, the cortical cells of Calliblepharis jubata are much larger (7-15 µm) although microscopic examination is required to differentiate between them (Dixon & Irvine, 1977).
