Notes     (Last Modified On 3/6/2009)
general taxon notes:

Andreaea mutabilis is easily recognized by the differentiation of its isodiametric basal marginal cells in contrast with the elongate, pitted, centrally located basal cells. The narrowly acuminate leaves with a long lanceolate upper part are different from those of A. rupestris. Another diagnostic feature of A. mutabilis is that its capsules split longitudinally from the base to the apex.
