TYPE SPECIES. — Halodiatrype salinicola Dayarathne & K.D.Hyde View in CoL , in Mycosphere 7 (5): 612-627 (2016).

DESCRIPTION

Sexual morph

See Dayarathne et al. (2016).

Asexual morph

(on PDA after 60 d at 25°C) libertella-like, in black conidial drops. Conidia falcate, hyaline, 1-celled, smooth, upper end subacute, base truncate, curved to nearly semicircular.

NOTES

Halodiatrype was introduced by Dayarathne et al. (2016) and is significantly different to other genera in this family by having ascomata lacking stromatal tissues,comparatively large ascospores with septa and a libertella-like asexual morph. Generally, Diatrypaceae species have well-developed ascostromata with aseptate ascospores ( Maharachchikumbura et al. 2015). In our phylogenetic analyses, species belonging to this genus formed a well-separated (75% ML, 0.92 PP) clade (clade B) along with the marine genus Pedumispora . Halodiatrype formed a well-separated (99% ML,90% MP,1.00PP) clade within Diatrypaceae ( Fig. 1 View FIG ) supported by ITS phylogenetic data ( Fig. 2 View FIG ). This study is the first report of an asexual morph for this genus from an axenic culture of Halodiatrype avicenniae .
