Tarzetta (Cooke) Lambotte
Index Fungorum number: IF 5358; MycoBank number: MB 5358
Tarzetta was established by Cooke (1879) as a subgenus of Peziza Fr. and later combined to the genus Tarzetta by Lambotte (1888). Its type species is Tarzetta catinus (Holmsk.) Korf & J.K. Rogers. Tarzetta was originally circumscribed as a member of the Pyronemataceae. Using four-gene phylogeny, Pyronemataceae was demonstrated as a paraphyletic group and then Tarzetta was placed in Tarzetta Geopyxis lineage (Hansen et al. 2013; Wang et al. 2016; Kumar et al. 2017). Ekanayaka et al. (2018) introduced the new family Tarzettaceae to accommodate Geopyxis, Hydnocystis, Hypotarzetta, Paurocotylis, Stephensia, and Tarzetta based on phylogenetic analyses of five combined loci of ITS, LSU, SSU, tef1-α, and rpb2 regions. Currently, Tarzetta comprises 21 species that have a widespread distribution in north temperate region (Kirk et al. 2008; Ekanayaka et al. 2018; van Vooren et al. 2019). In China, only four species have been reported, i.e., Tarzetta catinus, T. confusa, T. cupularis, and T. linzhiensis (Kirk et al. 2008; Zhuang 2014; Hyde et al. 2021). The apical ends of the paraphyses often used as an important diagnostic character to separate species in Tarzetta. However, van Vooren et al. (2019) suggested that the morphology of paraphyses may differ with the age of the collection or the area of hymenium that we observed.
