Type species
The type species (lectotype) of the genus Meredithia is Meredithia microphylla (J.Agardh) J.Agardh.

Status of name
This name is of an entity that is currently accepted taxonomically.

No synonyms are currently included in AlgaeBase.

General environment
This is a marine species.

Plants typically associated in small clumps, individual plants 2.5-4.0 cm wide and to 2.5 cm tall. Blades stipitate, stipe simple or branching, 1.5 mm wide in lowest portion narrowing above dichotomies. Older eroded blades occur lower on the stipe, marginally attached, leaving bumps (scars) as they senesce, terminal blades oval to elongate appearing eccentrically peltate(?), but this appearance seems to derive from a spiraling of the blade at the point of attachment to the stipe. Blades typically entire or slightly lobed, margins broadly undulate, forming typically stipitate blades from the margins of subtending blades. Blades 250-400 µm thick in longitudinal section near the margin with a moderately to densely filamentous medulla; 2-3 layered inner cortex some cells of which are obviously stellate; outer cortex dorsiventral with 1-2 versus 2(-3) cell layers on the ventral and dorsal surfaces, respectively. Ventral cortical cells 2.5-3.5 µm wide, 5.0-7.5 µm tall; dorsal cortical cells 2-3 µm wide, 3-5(-7.5) µm tall, outermost ones at times becoming strongly obclavate and up to 10 µm high, giving the impression of being spermatangial mother cells, but which nonetheless remain pigmented and never bear spermatangia. Best identified by comparison to the type COI-5P barcode sequence (GenBank: KF280937).
