Notes – Spegazzinia was introduced by Saccardo (1880) as a hyphomycetous genus. Spegazzinia was classified in Apiosporaceae, Sordariomycetes (Hyde et al. 1998) based on its morphological characteristics. Tanaka et al. (2015) referred Spegazzinia in Didymosphaeriaceae based on molecular evidence of S. deightonii (S. Hughes) Subram. and S. tessarthra (Thambugala et al. 2017b). The asexual morphs of Spegazzinia have been reported for Didymosphaeriaceae. One of the most important morphology characters of Spegazzinia is its pleomorphism (Mena-Portales et al. 2017). Most species produce two types of conidia in the same mycelium; type “a” which are composed by 4–8 subglobose, very dark cells with very long spines, which are very similar in morphology and size in almost every species; and type “b” which are subsphaerical or broadly ellipsoid, in general flattened in one plane, cruciately septate or muriform, almost always pale brown and smooth, with short spines or lobed (Mena-Portales et al. 2017). There are 14 Spegazzinia species in Species Fungorum (2020).

 

Type species: Spegazzinia ornata Sacc., Michelia 2(no. 6): 172 (1880).
