 DESCRIPTION AND ILLUSTRATION. — seeAbdel-Wahab et al. (2017).   
DISTRIBUTION. — Saudi Arabia.  NOTES  
 Halocryptovalsa avicenniae, comb. nov. (synonym of Cryptovalsa avicenniae) and its asexual stage (libertella-like) is kown from Avicennia marina from Australia and on driftwood from Saudi Arabia (Abdel-Wahab et al. 2017). This species morphologically resembles Cryptovalsa species as well as the new species, Halocryptovalsa salicorniae Dayarathne & K.D.Hyde, sp. nov. Halocryptovalsa avicenniae, comb. nov., has larger ascomata than other members of Diatrypaceae, lacks papillial furrows on the ascomata and has more ascospores per ascus (Abdel-Wahab et al. 2017). Therefore, it can be clearly distinguished from the previously described marine species, Cryptovalsa halosarceiicola, C. mangrovei and C. suaedicola. The presence of the asexual stage (libertellalike) in the same stroma is characteristic of this species. Morphological variation between Hcr. avicenniae and Hcr. salicornia e are compared in Table 4.   
 Halocryptovalsa Dayarathne & K.D.Hyde, gen. nov., species do not form a stable position in our phylogenetic study. In our phylogenetic analyses with combined ITS+Btub neither Cryptovalsa rabenhorstii strains nor any other Cryptovalsa species grouped with Halocryptovalsa Dayarathne & K.D.Hyde, gen. nov., species, confirming Halocryptovalsa Dayarathne & K.D.Hyde, gen. nov., and Cryptovalsa as phylogenetically distant. Halocryptovalsa avicenniae, comb. nov., lack of ITS and BTUB sequence data in the GenBank. Therefore, we conducted a separate phylogenetic study with combined 18S and 28S rDNA sequences by including both Hcr. avicenniae and Hcr. salicorniae with selected diatrypaceous species following Abdel-Wahab et al. (2017) (Figs 3; 4). According to our second phylogenetic analyses of 18S and 28S rDNA sequences, Halocryptovalsa avicenniae, comb. nov., strains formed a single clade with Hcr. salicorniae. Hence, by considering both morphological and phylogenetic affinities we accomadated these two species under the newly introduced genus Halocryptovalsa Dayarathne & K.D.Hyde, gen. nov.
