Neosonderhenia

Neosonderhenia Crous, in Crous et al., Stud. Mycol. 94: 200 (2019).

Index Fungorum number: IF 832025; Facesoffungi number: FoF 04734, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.

Associated with leaf spot. Sexual morph: Ascomata pseudothecial, immersed, with central ostiole; wall of 3–6 layers of brown textura angularis. Asci 8-spored, bitunicate, sessile, fasciculate with small ocular chamber. Ascospores hyaline, smooth, guttulate, median septate. Asexual morph: Conidiomata globose, immersed, subepidermal with central ostiole, brown; wall of 3–6 layers of brown textura angularis. Conidiophores reduced to inconspicuous conidiogenous cells lining the cavity, doliiform, pale brown, proliferating percurrently. Paraphyses hyaline, subcylindrical, sparsely septate. Conidia solitary, medium brown, verrcuculose, distoseptate with central pore at each septum, apex subobtuse, base truncate.

Type species: Neosonderhenia eucalypti Crous

Notes: Neosonderhenia is characterized by a pseudothecial ascomata with central ostiole, bitunicate asci, hyaline, smooth, guttulate ascospores. The asexual morph is characterized by globose, immersed conidiomata, conidiogenous cells proliferating percurrently and distoseptate verrcuculose conidia with a central pore. Neosonderhenia resembles Sonderhenia in having conidiomatal paraphyses and is best differentiated based on their DNA phylogeny.
