Taxonomic notes
As to type, the names Acrosorium reptans (P.L. Crouan & H.M. Crouan) Kylin and A. uncinatum (Turner) Kylin are based on forms of Cryptopleura ramosa (Wynne 1989; Maggs & Hommersand 1993, p. 254-55); however, some reports of A. reptans are based on specimens of A. venulosum and some on Cryptopleura ramosa. Individual examination of specimens is therefore necessary to establish validity of many records. John et al. (2004) cite Acrosorium uncinatum (Turner) Kylin, Nitophyllum uncinatum (Turner) J. Agardh and Aglaophyllum laceratum Mont. as synonyms of this species.

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

According to Maggs & Hommersand (1993: 255), Acrosorium uncinatum sensu Kylin (1924: 77) [non Fucus laceratus var. uncinatus Turner (1808: 68) is a synonym of Acrosorium venulosum (Zanardini) Kylin (1924: 77). - (26 Jan 2009) - Wendy Guiry
