The phylogenetic placement of this genus was determined by Crous et al. (2018a). Five epithets are listed in Index Fungorum (2020), but sequence data are available for only two species (P. fissurella and P. shathenatiana, Crous et al. 2018a). We were unable to obtain fresh collections to illustrate this genus. Thus, a drawing of P. shathenatiana and P. salicorniae is provided (Fig. 1). Morphological characters can be seen in Crous et al. (2018a).
Type species: Phaeotheca fissurella Sigler, Tsuneda & J.W. Carmich., Mycotaxon 12(2): 450 (1981).
Other accepted species: Species Fungorum – search Phaeotheca.

Notes – a–c = Phaeotheca salicorniae (redrawn from Crous et al. 2016b, CPC 27406), d–f = Phaeotheca shathenatiana (redrawn from Crous et al. 2018a, MSX102094). Scale bars: a, d–f = 10 μm.
