Hyalosphenia spec.

Diagnosis: shell exceedingly transparent, colorless, without any pores, but finely granulated; pseudostome broader as with H. cuneata. Greatly compressed, but without any indication of a broad rounded keel; nucleus with central nucleolus which contains some spheres.

Dimensions: Length 43 µm (n=1).

Ecology: In Sphagnum from Tirol, Austria, collected by Angie Opitz in 2015.

Remarks: This species differs from H. cuneata by its smaller size, its broader pseudostome, the structure of the nucleus and a finely granulated surface of the shell. It differs from H. punctata in size and structure of the nucleus and shell.
