Eponomy
"Named for Gerald T. Kraft for his unequalled contributions to our knowledge of the algal flora of Lord Howe Island and his enduring mentorship of GWS."

General Environment
This is a marine species.

Description
Plants forming small spreading clusters of simple, largely prostrate, at times anastomosing, blades. Individual blades stipitate, stipes 1.5-2.0 mm wide and tall, positioned eccentrically; blades typically 1-3 cm in diameter, peltate and round to oval with undulate to crispate margins. Blades 200-275 µm thick in longitudinal section near the margin, composed of a moderately dense filamentous medulla with occasional, darkly staining stellate medullary cells observed throughout the section. Inner cortex of 2-3 cell layers of relatively large isodiametric (cytoplasm in rehydrated material having a stellate appearance) cells forming a distinctive transition to the central medulla; outer cortex (strongly) dorsiventral with 1-2 layers of slightly larger (3-6 µm wide, 5-8 µm tall) versus 2-3 layers of slightly smaller (3-5 µm wide, 5.0-7.5 µm tall) cells on the ventral and dorsal surfaces, respectively. Reproduction not observed. Best identified by comparison to the type COI-5P barcode sequence (GenBank: KC157615).
