Crypho + gnomonia, referring to the cryptic stromata on hosts.

Cryphognomonia pini C.M. Tian & N. Jiang

Pseudostromata erumpent, causing a pustulate bark surface. Central column yellowish to brownish. Stromatic zones lacking. Perithecia conspicuous, flask-shaped to spherical, umber to fuscous black, regularly scattered. Paraphyses deliquescent. Asci fusoid, 8-spored, biseriate, with an apical ring. Ascospores hyaline, clavate to cylindrical, smooth, multi-guttulate, symmetrical to asymmetrical, straight to slightly curved, bicellular, with a median septum distinctly constricted, with distinct hyaline sheath. Asexual morph: not observed.

Cryphognomonia was classified as a new genus in Gnomoniaceae throughout molecular data and the characteristics of sexual morph. Morphologically, Cryphognomonia can be distinguished from the other genera by pseudostromata and ascospores with obvious hyaline sheath.
