Periconiaceae

Periconiaceae Nann.

Index Fungorum number: IF 81124; Facesoffungi number: FoF 06657

 

Saprobic, pathogenic or endophytic on various hosts. Sexual morph: Ascomata scattered to gregarious, immersed, semi-immersed or erumpent, black or brown, globose to subglobose. Neck central, papillate, with hyaline periphyses. Peridium in longitudinal section composed of several layers of thin or thick-walled, pale brown to brown cells. Hamathecium comprising cellular, branched, anastomosed, pseudoparaphyses. Asci bitunicate, fissitunicate, oblong to cylindrical, 8-spored, with a short pedicel and a shallow ocular chamber. Ascospores 2–3-seriate, broadly fusiform, hyaline, 1-septate, smooth-walled, with an entire sheath. Asexual morph: Hyphomycetous. Conidiophores macronematous or micronematous, mononematous, pale to dark brown, branched or unbranched, septate, thick-walled, smooth or verruculose. Conidiogenous cells are monoblastic or polyblastic, integrated or discrete, ovoid to clavate formed on the terminal or intercalary of the stipe, sometimes with small, pimple-like pores. Conidia sphaerical to fusoid-ellipsoidal, catenate or solitary, pale to dark brown, aseptate, sometimes with a minute, unthickened pore at base, smooth-walled or verruculose. (Descriptions from Hongsanan et al. 2020)

 

Type genus: Periconia Tode

 

Notes: Historically, Periconiaceae has long been neglected and Periconia was included in Massarinaceae (Zhang et al. 2009, Hyde et al. 2013). Tanaka et al. (2015) resurrected Periconiaceae as a sister taxon of Massarinaceae in Massarineae (Pleosporales, Dothideomycetes) based on their phylogenetic analyses. Phukhamsakda et al. (2016) showed Periconiaceae and Massarinaceae diverging in the late Cretaceous period (around 70 MYA). Four genera are accepted in Periconiaceae. (Notes from Hongsanan et al. 2020)
