Cell walls as taxonomic markers in polish species of the genus odontoschisma (dum.) Dum. (Hepatcae, cephaloziaceae)

摘要

To get valuable diagnostic characters, the structure of cell walls was studied with use of two stains (Ruthenium Red-RR- and Resorcine Blue-RB) and in polarized light. As far as the stem structure is concerned, European species of the genus Odontoschisma fall into two groups; in Odontoschisma elongatum and in Odontoschisma macounii a thick, frequently com- Pletely obscuring cell lumen, "lining layer' is present.
