Cryptosphaeria Ces. & De Not.

NOTES

Cryptosphaeria Ces. & De Not. was introduced by Greville (1822). Taxonomic significance of this genus remained unclear as the original author incorporated a number of disparate taxa under this genus viz. Botryosphaeria species, due to some morphological similarities such as ascostromata characters ( Rappaz 1987). Cesati & De Notaris (1863) re-used the name Cryptosphaeria and designated Cryptosphaeria millepunctata as the type species, although Cr. eunomia , is now the widely accepted name for the type ( Clement & Shear 1931). Cryptosphaeria Ces. & De Not. (1863) has been adopted in favour of Cryptosphaeria Grev. ( Rappaz 1989) . Cryptosphaeria species produce 8-spored, spindle-shaped asci with long stipitate and subolivaceous to brown ascospores ( Glawe & Rogers 1984; Rappaz 1987; Trouillas et al. 2011). This genus comprises 13 species of which Cr. eunomia and Cr. mangrovei have been reported as saprobes from marine habitats ( Trouillas et al. 2015; Jones et al. 2015). Recently, Cr. mangrovei has been synonymized with Halodiatrype mangrovei , based on morphological characteristics ( Dayarathne et al. 2016) (see description and illustration under Halodiatrype mangrovei . Currently, combined ITS (ITS1, 5.8s and ITS2 regions) and Btub gene sequence data coupled with morphological characteristics are used to differentiate Cryptosphaeria species ( Acero et al. 2004, Trouillas et al. 2010a). Our phylogenetic analyses showed that Cryptosphaeria is polyphyletic, as reported by Shang et al. (2017) and Senwanna et al. (2017).
