Halofilum Darienko & Pröschold.

Halofilum is a filamentous genus of mostly coastal marine algae that accommodates species previously assigned to Dilabifilum . The short-branched, dense and easily disintegrable filaments consist of vegetative cells containing parietal chloroplasts with pyrenoids ( Fig. 23 ) and reproduce by budding or cell division ( Darienko & Pröschold 2017). The genus currently harbours three species ( Guiry & Guiry 2022) including H. ramosum , which was isolated from Wahlenbergiella and Hydropunctaria lichens ( Gasulla et al. 2019) as well as from stone cracks of coastal rocks in Porth Trecastell, United Kingdom and walls of archaeological remains in Carthage, Tunisia ( Darienko & Hoffmann 2010; Darienko & Pröschold 2017).
