Spegazzinia Sacc.

Spegazzinia Sacc. Padova: [1] (1879)

Notes.

Spegazzinia is a diverse, hyphomycetous genus introduced by Saccardo (1880) to include S. ornata as the type species. Spegazzinia species have been reported mainly as saprobes on litter of tropical, subtropical, and temperate vascular plants ( Matsushima 1980; Lu et al. 2000; Manoharachary and Kunwar 2010; Thambugala et al. 2017). Additionally, some have been identified as endophytes (e. g., S. tessarthra and S. bromeliacearum ) ( Manish et al. 2014; Crous et al. 2019). Apart from that, Spegazzinia species have also been found in soil ( Ellis 1971). The morphological characteristics of Spegazzinia are quite distinct from those of other hyphomycetous genera due to its pleomorphism ( Mena-Portales et al. 2017). They have two types of conidia in the same mycelium, such as α and β conidia. Some species have spines in both types of conidia, while some taxa do not bear spines. Currently, 28 Spegazzinia species are listed in Species Fungorum (2025). In this study, we introduce a new host record of S. deightonii from a dead leaf of Arundo pliniana in China.
