Index Fungorum, Facesoffungi, MycoBank, GenBank

Classification: Chaetosphaeriaceae, Chaetosphaeriales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Etymology: refers to its morphological similarity with Zanclospora 

Diagnosis: Similar to Zanclospora, but differs in aseptate, fusiform to narrow-ellipsoidal ascospore, and unilateral phialides produced along the midsection of setiform conidiophores.

Teleomorph: Ascomata globose to sub-globose, dark brown, solitary to densely gregarious, superficial on a thin subiculum, distinctly papillate. Ascomatal wall in surface view, opaque in water, textura angularis in lactophenol, composed of pseudoparenchymatic cells. Ascomatal apex papillate, opaque. Paraphyses unbranched, septate, tapering. Asci cylindro-clavate, short stalked, unitunicate, thin-walled, apical ring not observed, with 8 ascospores irregularly arranged. Ascospores hyaline, fusiform to narrow-ellipsoid, one-septate. Anamorph: Conidiophores setiform, solitary, erect, unbranched, multiseptate, brown, tapering to an apical phialide, several unilateral phialides produced along the midsection. Conidiogenous cells mono- or poly-phialides, ovoid, brown, produced along the conidiophore midsection, with several collarettes in a sympodial arrangement, or sometimes with percurrent proliferations; collarettes small, funnel-shaped. Conidia narrow fusiform, hyaline, one-celled.

Ecology/Substrate/Host: Saprobe on decaying wood of branches (Adapted from Fernández and Huhndorf 2005).

Geographical distribution: Panama (Fernández and Huhndorf 2005).

Description and illustration: Fernández and Huhndorf (2005).

Notes: The new genus is created for Chaetosphaeria minuta, which in our phylogenetic analysis is closely connected with Zanclospora but forms in a distinct linkage. The diagnostic characters for the genus are hyaline, fusiform to narrow-ellipsoid, aseptate ascospore, and Zanclospora-like anamorph with setiform conidiophores, several unilateral phialides produced along the midsection, and hyaline, aseptate, fusiform conidia. It differs from Zanclospora in aseptate ascospore and unilaterally arranged phialides in one side along the midsection of conidiophores (Fernández and Huhndorf 2005; Réblová et al. 2021a).

Type species: Zanclosporiella minuta (F.A. Fernández & Huhndorf) W.P. Wu & Y.Z. Diao (≡ Chaetosphaeria minuta F.A. Fernández & Huhndorf).

Other accepted species: Species Fungorum – search Zanclosporiella.
