Aquatospora

Aquatospora W. Dong, H. Zhang & K.D. Hyde

 

Index Fungorum number: IF557903; Facesoffungi number: FoF09245

Etymology: referring to aquatic habitat of this fungus

 

Saprobic on decaying wood submerged in freshwater. Sexual morph: Ascomata black, scattered or gregarious, superficial, hemisphaerical to conical, base flattened, carbonaceous, with ostiolate papilla. Ostiole central, relatively broad, circular, black. Peridium uneven in width, carbonized, composed of black amorphous layer, whose cells are obscured. Pseudoparaphyses numerous, trabeculate, filiform, hyaline, sparsely septate. Asci 8-spored, bitunicate, clavate to narrowly ellipsoidal, with a short pedicel, apically rounded. Ascospores 2–4-seriate, hyaline, septate, subcylindrical, thin-walled, smooth. Asexual morph: Undetermined. (Description from Dong et al. 2020).

 

Type species: Aquatospora cylindrica W. Dong, H. Zhang & K.D. Hyde

 

Notes: Aquatospora clusters with Acrocordiopsis Borse & K.D. Hyde and Xenoastrosphaeriella Jayasiri et al. with low bootstrap support (Dong et al. 2020). Acrocordiopsis is a problematic genus, which was placed in Salsugineaceae by Hyde et al. (2013) and Caryosporaceae by Ariyawansa et al. (2015). Acrocordiopsis was referred to Salsugineaceae (Wijayawardene et al. 2018, 2020) based on some common morphology between Acrocordiopsis and Salsuginea K.D. Hyde (Borse and Hyde 1989; Hyde 1991). Acrocordiopsis clustered distantly from Salsuginea in the phylogenetic tree of Zhang et al. (2018) and close to Aquatospora in the study of Dong et al. (2020). Xenoastrosphaeriella differs from Aquatospora in having paler end cells of ascospores (Hawksworth and Boise 1985; Phookamsak et al. 2015; Jayasiri et al. 2019). Aquatospora shares similar characters with Astrosphaeriellaceae members in having large, erumpent to superficial, hemisphaerical or conical, carbonaceous ascomata with nearly flattened bases (Borse and Hyde 1989; Ariyawansa et al. 2015; Phookamsak et al. 2015). However, the unique combination of morphology of clavate to narrowly ellipsoidal asci, hyaline, cylindrical ascospores and molecular characters warrant Aquatospora as a new genus (more details see key to freshwater genera of Astrosphaeriellaceae). (Notes from Dong et al. 2020)
