Jarxia D. Hawksw., Stud. Mycol. 31: 93 (1989).
MycoBank number: MB 25310; Index Fungorum number: IF 25310; Facesoffungi number: FoF 07879; – 2 morphological species (Species Fungorum 2020), molecular data unavailable.
Type species: Jarxia thelenula (Müll. Arg.) D. Hawksw., Stud. Mycol. 31: 95 (1989).
≡ Microthelia thelenula Müll. Arg., Bot. Jb. 6: 416 (1885).
Notes: Jarxia contains two non lichen-forming species (Doilom et al. 2018; Index Fungorum 2020). Doilom et al. (2018) re-examined the syntype of J. thelenula which has the same morphology as the holotype (Hawksworth 1989), thus they agree to place this genus in Naetrocymbaceae.
