Jobellisiales D’souza & K.D. Hyde, ordo novusIndex Fungorum number: IF551134

Jobellisiales is a monotypic order in the class Sordariomycetes, subclass Diaporthomycetidae. It includes a single family Jobellisiaceae characterized by saprobic lignicolous taxa found in terrestrial and freshwater habitats. Sexual morph: Ascomata superficial, basally immersed, brown to black, or externally with yellowish pigments, papillate perithecial. Peridium 3-layered, with an orange, middle wall layer. Hamathecium with paraphyses. Asci unitunicate, cylindrical, with a large, refractive, J-, apical ring. Ascospores uniseriate, 1-septate, coloured, with germ pores. Asexual morph: Undetermined.

Type family: Jobellisiaceae

Notes: This order encompasses taxa that possess relatively large, superficial ascomata, a three layered, thick peridium, cylindrical asci and one septate ascospores. Ascomata of Jobellisia luteola (Ellis & Everh.) M.E. Barr are peculiar in appearing orange to yellow brown, whereas those of J. barrii Huhndorf et al. and J. viridifusca K.M. Tsui & K.D. Hyde have a bright orange middle wall layer (Ranghoo et al. 2001, Liu et al. 2012). The family Jobellisiaceae was introduced by Réblová (2008) as a monotypic family and currently includes seven species. Réblová (2008) using LSU rDNA sequence analysis showed that the closest relatives to Jobellisiaceae are Diaporthales, Calosphaeriales and Togniniaceae. No asexual morph is reported for this order. In our phylogenetic analysis this order is closest to Calosphaeriales (Maharachchikumbura et al. 2015).

Type species: Jobellisia luteola (Ellis & Everh.) M.E. Barr
