Notes.
Réblová (2006) designated the lectotype (illustration; Tode 1791: fig. 79) and epitype (Fries´s Scleromyceti Sueciae 116, decayed wood, PRM 666367) of C. rostrata. Untereiner (1993), in her revision of the genus Endoxyla, cited Ceratostomella ampullasca (Saccardo 1882) and Endoxyla laevirostris (Munk 1965) as synonyms of C. rostrata. However, recent collections and molecular DNA data have revealed that these two species are conspecific and were reclassified as Natantiella ligneola (Réblová and Štěpánek 2009). There are numerous records of C. rostrata in MyCoPortal; however, these may represent species of Endoxyla, as the synonymy of this species was only recently clarified. Accurate identification would require a thorough examination of the herbarium specimens cited, which are housed in various collections around the world.
Ceratostomella rostrata is somewhat similar to C. cuspidata; however, it differs in having larger ascomata and pale brown, allantoid to suballantoid, narrower ascospores measuring 4.5–6 × 1.5–2 μm. These ascospores are typically arranged in a fascicle in the upper part of the ascus or are 2–3 - seriate within the ascus. Molecular data for this species are not available.
