Notes – Rappaz (1995) introduced Barrmaelia which resembles Diatrypaceae due to its allantoid ascospores, but in contrast, has short-pedicellate asci and J-, ascal rings. Rappaz (1995) combined six species in Barrmaelia (B. macrospora, B. moravica, B. oxyacanthae, B. picacea,
B. pseudobombarda, and B. sustenta) and described one new species, which he also selected as the generic type, B. rhamnicola based on morphology. Maharachchikumbura et al. (2016b) regarded Barrmaelia as a xylariaceous genus with a conidial morph that did not belong to nodulisporium-like or geniculosporium-like taxa. Wendt et al. (2018) placed Barrmaelia in Xylariales genera incertae sedis due to its unconfirmed affinities to the other families. A study on natural classification of Graphostromataceae, Hypoxylaceae, Lopadostomataceae and Xylariaceae has placed the genus in the Diatrypaceae based on their morphology and tentative phylogeny (Daranagama et al. 2018). However, the clade comprising Barrmaelia and Entosordaria within Xylariaceae sensu lato has been introduced as Barrmaeliaceae (Voglmayr et al. 2018). 

Barrmaelia rhamnicola, the type species of the genus was introduced by Rappaz (1995) and epitypified by Voglmayr et al. (2018). It is characterized by often slightly curved, relatively large ascospores, which are filled with conspicuous oil drops and lack a germ slit. The known libertella-like asexual morph has been shown for B. rhamnicola. Barrmaelia rhamnicola is illustrated in this entry.

Type species: Barrmaelia rhamnicola Rappaz, Mycol. helv. 7(1): 130 (1995).

Other accepted species: Species Fungorum – search Barrmaelia.
