Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1
Classification: Chaetosphaeriaceae, Chaetosphaeriales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Etymology: Refers to its similarity on conidial morphology with Calceispora Matsush.
Diagnosis: Similar to Codinaea s. str. and Calceispora in well-developed conidiophores, phialidic conidiogenous cells, and hyaline, aseptate conidia bearing setulae, but differs in rough-walled and monophialidic conidiogenous cells bearing inconspicuous collarettes, and subglobose to ellipsoidal conidia with thick wall and one setula at each end.
Description on the natural substrate: Saprobe on dead branches. Colonies effuse, hairy, dark brown. Mycelium partly superficial and partly immersed, composed of pale brown to brown, branched and septate hyphae. Teleomorph: Unknown. Anamorph: Conidiophores macronematous, simple, erect, straight, or slightly flexuous, cylindrical, dark brown, septate, smooth or verruculose, thick-walled, proliferating percurrently. Conidiogenous cells integrated, terminal, monophialidic, cylindrical, smooth or verruculose, apex with narrow sporulating loci without distinct periclinal thickening, collarette inconspicuous. Conidia holoblastic, acrogenous, solitary, subglobose to ellipsoidal, aseptate, hyaline, smooth, with one slender at each end. Conidia secession schizolytic.
Ecology/Substrate/Host: saprobe on dead branches of broad leaf tree.
Geographical distribution: China.
Notes: Calceisporiella is morphologically similar to Codinaea s. str. and Calceispora in producing well-developed conidiophores, phialidic conidiogenous cells, and hyaline, aseptate conidia with unbranched setulae, but differs from them in rough-walled and monophialidic conidiogenous cells bearing inconspicuous collarettes, and the globose to ellipsoidal conidia with thick wall and one setula at each end (Carmichael et al. 1980; Sutton 1993; Seifert et al. 2011; Réblová et al. 2021). The appendages in the type species of Calceispora are cellular and much wider, and differs from the setulae appendage in Calceisporiella. Phylogenetically Codinaea and Calceisporiella and Codinaea s. str. are distinctly related and grouped into two different clades in the phylogenetictree
