Darksidea D.G. Knapp, Kovács, J.Z. Groenew. & Crous, Persoonia 35: 95 (2015)
Index Fungorum number: IF 810760; Facesoffungi number: FoF 08258, 6 morphological species (Species Fungorum 2021), 6 species with molecular data.
Endophytic on host. Sexual morph: Ascomata globose, brown; ostiole not reported; wall of 3–4 layers of brown textura angularis, surface of textura epidermoidea. Pseudoparaphyses intermingled among asci, hyaline, septate, hyphal, anastomosing. Asci bitunicate, clavate to ellipsoid, with weakly developed apical chamber, stipitate, 4–6-spored. Ascospores multiseriate in asci, hyaline, guttulate, aseptate, thick-walled, ellipsoid. Asexual morph: Unknown (Adapted from Knapp et al. 2015).
Type species: Darksidea alpha D.G. Knapp, Kovács, J.Z. Groenew. & Crous
Notes: Darksidea was introduced by Knapp et al. (2015) with D. alpha as type species. Darksidea belongs to dark septate endophytes, the enigmatic root colonizing fungal group ‘on the dark side’. Darksidea is characterized by globose, brown ascomata, hyaline, septate asci, clavate to ellipsoid asci, guttulate, aseptate ascospores. Darksidea is a distinct genus both morphologically and phylogenetically in Lentitheciaceae.
