Blytt's Andreaea Moss - Andreaea blyttii
State Rank Reason (see State Rank above)
Distribution data in BIOTICS had Distribution Confidence as "Reported but unconfirmed" with no explanatory notes (Spribille report). FNA 2014 does not show this in Montana.
General Description
Plant: Small to large, usually in dense tuft. Red-black, blackish, or green-brown. Stems erect and irregularly branched. Rhizoids at base of plant. Central strand is absent.
Leaf: Leaf curved or second to straight, wide-spreading to squarrose, short-lanceolate, and widest near base. Apex oblique or symmetric. Costa is absent. Margins entire.
Leaf Cells: Basal laminal cells short- to long-rectangular. Marginal cells are rounded-quadrate to short-rectangular, with thicker-walls, often pitted, and straight. Median laminal cells quadrate to short-rectangular with lumens rounded, and rectangular or irregularly stellate. Median laminal cells in 1-layer with occasional patches of 2-layers. Laminal papillae usually present, large, and whitish.
Seta/Capsule: Setas are essentially absent. Capsules are erect, elliptic, and open with 4 lateral valves.
Diagnostic Characteristics
Species is highly variable and usually identified by the process of elimination. Plants identified as A. alpestris differ by having straight leaves with low papillae, but treated as a high elevation form of A. rupestris in the FNAv27.
