In the late Visean Glösa moss assemblage, Type I specimen KS27–074 is a nearly complete single-layered leaf with a central band of narrower cells and small pores in the periclinal walls; this fragmentary assemblage does not document complete plants or securely identify living moss taxa. This navigation entry is not a phylogeny or a complete taxon dossier.
