Jirivanaea is a genus of mosses in the family Sematophyllaceae. It contains five species.
Etymology
Jirivanaea was named for Jiří Váňa, a bryologist from the Czech Republic.
Range
The species within Jirivanaea occur in South America, Central America, Mexico, and some Caribbean islands.
History
A 2017 paper determined that Acroporium and Sematophyllum were paraphyletic on the basis of morphological and molecular data. A new genus, Vitalia, was proposed, with Vitalia caespitosa (formerly Acroporium caespitosum) designated as the type species. However, the generic name Vitalia is already in use in fungal taxonomy. Jirivanaea is a substitute name for the same four species. In 2023, a new species was described from Brazil.
Description
Jirivanaea is a pleurocarpous moss, meaning its main stem is indeterminate and its branches may morphologically differ from it. Carvalho-Silva et al. describe Vitalia as being "robust with galeate leaves and brotherelloid cells." The stems of Jirivanaea are creeping, freely branched, and lack a central strand and paraphyllia. Leaves differ little between stem and branch; are erect, never homomallous, galeate, oblong-ovate or ovate, and concave; with entire margins and without a costa. Cells are linear and smooth, while alar cells are inflated and colored. Setae are elongate and smooth, with capsules sub-erect to pendent; the annulus is not differentiated, and the operculum long-rostrate. Spores are spherical and finely papillose.
