Paulbroadya Darienko & Pröschold.

The thallus of Paulbroadya consists of prostrate system, formed from rounded cells or cell-packages and erect system, formed by dense unilateral or bilateral branches (Fig. 25). The morphology is very similar to other taxa previously treated under Dilabifilum . These genera can be distinguished only by means of genetic markers (Darienko & Pröschold 2017). One of the two described Paulbroadya species (Guiry & Guiry 2022), P. petersii, was isolated from Hydropunctaria and Verrucaria species (Thüs et al. 2011; Darienko & Pröschold 2017) but was not, to date, recorded in free-living state.
