Cryphaea F.Weber is a genus of mosses in the family Cryphaeaceae, within the order Hypnales and class Bryopsida (the "true mosses," phylum Bryophyta, kingdom Plantae). The genus was validly published by Friedrich Weber in 1814 in the Tabula Exhibens Calyptratarum Operculatarum.
Cryphaea has a complicated taxonomic history: over its history, 165 species-rank names have been applied within the genus, but only a fraction are recognized in modern nomenclature — Wikipedia's summary lists 26 currently accepted species, while the GBIF Backbone Taxonomy recognizes 34 accepted species as descendants of the genus. This gap reflects extensive synonymization typical of moss taxonomy, where many historical names described the same taxon under different authors or regional floras.
Occurrence data compiled by GBIF shows the genus is recorded across a wide geographic span rather than being confined to a single continent. The largest numbers of records come from Atlantic and Western Europe — the United Kingdom, France, Belgium, the Netherlands, Ireland, Germany, Spain, and Portugal — with national checklists also confirming its presence in Scandinavia (Denmark, Norway, and Sweden, where it is documented as native). Substantial records also exist from the Americas (the United States, Mexico, Bolivia, and Colombia) and from Oceania (New Zealand and Australia), pointing to a broadly temperate-to-subtropical, near-cosmopolitan distribution rather than a narrow regional range.
Among the species placed in the genus, Cryphaea heteromalla and Cryphaea jamesonii are highlighted in general reference sources as representative members; Cryphaea heteromalla is the species most commonly illustrated in general encyclopedic treatments of the genus.
Distribution
Occurrence records place Cryphaea most densely across Atlantic and Western Europe (UK, France, Belgium, Netherlands, Ireland, Germany, Spain, Portugal), with national checklists confirming native presence in Scandinavia (Denmark, Norway, Sweden). Further substantial records extend to the Americas (US, Mexico, Bolivia, Colombia) and Oceania (New Zealand, Australia), indicating a broadly temperate-to-subtropical, near-cosmopolitan range.
Taxonomy Notes
The genus was published by Friedrich Weber in 1814. Its species-level taxonomy has been heavily revised over time: about 165 species-rank names have historically been applied within Cryphaea, but current sources disagree on how many remain accepted — 26 per a Wikipedia summary versus 34 accepted descendants in the GBIF Backbone Taxonomy — reflecting ongoing synonymization common to moss genera.
