The genus Parascutellinia is revised and amended, based on examinations of the type specimens from Humaria carneosanguinea, Lachnea violacea, Lachnea iuliana, Parascutellinia fuckelii, and Peziza arcte-spora. In addition, numerous collections of Parascutellinia carneosanguinea have been studied and sequenced. Phylogenetic analysis revealed that, contrary to earlier assumptions, it represents one single species. Therefore, H. carneosanguinea, L. violacea, and P. arctespora are considered conspecific. L. iuliana is excluded from Parascutellinia and considered conspecific with Trichophaea woolhopeia. Based on type examination and sequencing (including recent collections) of Parascutellinia fuckelii, the latter is also excluded from this genus, and the new genus Spaniodiscus is proposed. In addition, a species morphologically similar to Parascutellinia fuckelii was examined and found to be morphologically and genetically different from Spaniodiscus. For this species, the new genus Fallacidiscus is proposed.
The genus Parascutellinia was published by Svrček (1975) with Lachnea violacea Velen. as type, considering this species different from Scutellinia (Cooke) Lambotte because of the type of hairs: superficial with a simple base vs. deeply rooted with usually forked base, respectively […]
