Dicarpella Syd. & P. Syd., Annls mycol. 18(4/6): 181 (1921)

MycoBank number: MB 1512; Index Fungorum number: IF 1512; Facesoffungi number: FoF 09976; 5 morphological species (Species Fungorum 2020).

Type species – Dicarpella bina (Harkn.) Syd. & P. Syd.

Notes – Dicarpella has seven species epithets in Index Fungorum (2020). Dicarpella georgiana was transferred to Mastigosporella as M. georgiana (Barr 1978). Wuestniopsis was proposed to accommodate Dicarpella georgiana and D. quercifolia (Reid & Dowsett 1990), while Dicarpella dryina has been linked to Tubakia seoraksanensis (Senanayake et al. 2017a, Braun et al. 2018). Therefore, currently Dicarpella comprises only D. bina, D. liquidambaris-styracifluae and D. rubicola. Sequence data for the type species are unavailable. The asexual morph of Dicarpella was reported as Tubakia (Belisario 1991) and a few Tubakia species have diplacella-like sexual morphs (Sogonov et al. 2008, Senanayake et al. 2017a, 2018, Braun et al. 2018). Due to the unavailability of sequence data for the type species in both genera, it cannot be confirmed that Dicarpella and Tubakia are congeneric. Hence, Senanayake et al. (2017a) placed this genus in Melanconiellaceae, which we follow here until molecular data is available.
