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.
