Taxonomic notes
Womersley (2003: 133) notes: "The type of Acrosorium ciliolatum has numerous short, slender, "cilia" on the margins and surface.... As Kylin (1929: 13) considered, A. ciliolatum is not specifically distinct from A. venulosum, and is the earliest name for this Acrosorium. Most descriptions under Acrosorium vunulosum or A. uncinatum state "gametophyes unknown". However, a few southern Australian collections (e.g. AD, A31152) with typical uncinate branches and agreeing well with this species, do bear cystocarps, and the description" (given by Womersley 2003) "of female stages is based on these." - (26 Jan 2009) - Wendy Guiry

General environment
This is a marine species.

Common names

(as Acrosorium venulosum (Zanardini) Kylin)
English: Red Hook Weed (Bunker et al. 2010).

Description
Flattened, membranous, deep-red fronds, 30-150(-200) mm long. Frond deeply divided into linear-lanceolate, irregularly branched segments, often terminating in hooks. Margins toothed, often ± proliferous. Frond traversed by network of microscopic veins, macroscopic veins absent. Womersley (2003: 131-133, figs 61, 62A, B) gives descriptions of the thallus and reproduction.

Habitat
On rocks and epiphytic, lower intertidal and subtidal, widely distributed, occasional. Womersley (2003: 133) gives the following data: Occurs mainly in sheltered situations in calm waters, or deeper water on rough-water coasts.
