Status: Native
Synonyms:
Mnium magnifolium Horik.
Mnium punctatum Hedw. var. elatum Schimp.
Rhizomnium perssonii T. Kop
Rhizomnium punctatum (Hedw.) T. Kop. var. elatum (Schimp.) T. Kop.
Rhizomnium magnifolium has rhizoids all the way the stem to the youngest leaves, a result of having rows of special cells called micronemata that lack chloroplasts. Rhizomnium punctatum does not have micronemata, and therefore does not have rhizoids all the way up the stem. R. magnifolium has a margin that is frequently red in color and is 2-stratose. The costa can end short of the leaf apex or go right up to the apex, but usually there is no apiculus present. R. magnifolium is found in upper elevation fens.
