Sammeyersia S.Y. Guo, E.B.G. Jones & K.L. Pang, in Abdel-Wahab et al., Bot. Mar.: 0.1515/bot-2016-0118, 15 (2017)
Lulworthiomycetidae, Lulworthiales, Lulworthiaceae, Sammeyersia
Index Fungorum number: IF 820458; Facesoffungi number: FoF 06955; 1 species with sequence data.
Saprobic on decayed wood. Sexual morph: Ascomata immersed or superficial, ostiolate, with a long neck, brown to black, solitary or gregarious, globose or subglobose to pyriform. Necks cylindrical, straight or curved, sometimes two on one ascoma. Peridium two-layered, composed of an outer layer of cells of textura angularis and an inner layer of elongated cells with huge lumina; inner layer thickened at the base of the neck, composed of cells with thickened and vastly melanized wall. Paraphyses absent. Asci unitunicate, 8-spored, elongate-fusiform or cylindrical, thin-walled, mature deliquescing. Ascospores hyaline, filamentous, curved, narrowing at each end into an elongate, conical process or apical chamber, acute or rounded, filled with mucus that is out through an apical pore. Asexual morph: Undetermined (adapted from Abdel-Wahab et al. 2017).
Type species: Sammeyersia grandispora (Meyers) S.Y. Guo, E.B.G. Jones & K.L. Pang, in Abdel-Wahab et al., Bot. Mar.: 0.1515/bot-2016-0118, 15 (2017)
Notes: Sammeyersia was introduced by Abdel-Wahab et al. (2017) to accommodate Sammeyersia grandispora which was earlier Lulworthia grandispora. Sammeyersia grandispora is identified by the length of the ascospores over 400 μm (Abdel-Wahab et al. 2017). The new isolate in the study conducted by Hyde et al. (2020) grouped with the S. grandispora isolates deposited in GenBank. Therefore, based on both morphological and phylogenetic data, the new isolate was identified as S. grandispora. Sammeyersia grandispora is illustrated in this entry (notes taken and modified from Hyde et al. 2020).
