NOTES

Halodiatrype salinicola has immersed ascomata with a cylindrical or subconical, periphysate ostiole, apically rounded, clavate asci and allantoid, 0-1-septate, light brown ascospores. Halodiatrype salinicola is distinguish from H. avicenniae by having unique ascomatal characters and apex composed of brown outer amorphous layer and inner yellow cells of textura porrecta and aseptate ascospores becoming 1-septate at maturity. This species shares some common features with Cryptosphaeria species such as ascomata that lack stromatic tissues and allantoid, light brown ascospores. However, our phylogenetic survey proved that this species is phylogenetically distantly placed from Cryptosphaeria , as reported by Dayarathne et al. (2016). Two strains of H. salinicola and strains of H. avicenniae formed a well-separated clade from all other genera in Diatrypaceae with high bootstrap support (99% ML/ 90% MP/ 1.00 PP).
