State Rank Reason (see State Rank above)
Known from 1 collection from Flathead County in 1895.
Plants: Acrocarpous, the tufts not crowded, 10(-25) mm (FNA 2014), light green, the stems erect and frequently branched (Lawton 1971).
Leaves: Crowded near top of stem, upright-spreading when wet, somewhat erect to slightly contorted when dry, 2-4 mm, ovate-lanceolate; apex abruptly acute to acuminate; margins plane, smooth or nearly so (FNA 2014) with upper leaves sometimes toothed towards apex (Lawton 1971); costa broad, not approaching apex closely (FNA 2014).
Leaf Cells: Laminal cells translucent, lax, oblong and rhombic to 6-sided, with thin walls and a smooth surface; distal cells similar in size to basal cells (FNA 2014).
Amblyodon dealbatus differs from Meesia species by its thin-walled and lax (swollen when wet, crumpling while drying out) laminal cells (FNA 2014).
