N. golemanskyi, after Todorov, 2010

Nebela golemanskyi Todorov, 2010

Diagnosis: Shell large, colourless and pyriform, with a distinct short neck about one fourth of the
body length, and a rounded aboral region. It is almost uncompressed laterally, has no lateral margins and lateral pores. The shell has a comparatively thick wall and is composed of characteristic voluminous, globular or rarely elongated, rounded and hollow siliceous plates with an average diameter of about 10–15 μm. Occasionally small diatom
frustules scattered sparsely over the surface are incorporated amongst the plates. There are usually large parts between plates interspersed with well visible small beads of organic cement. The aperture is roughly circular to oval, truncate but not convex and bordered by a thin collar of organic cement.

Dimensions: Length 198-219 µm; width 111-132 µm; aperture 36-40 X 29-33 µm; W/L ratio 0.52-0.61 (n=24).

Ecology and distribution: Wet Sphagnum peatlands (1800–2000 m a.s.l.) in the Vitosha Mountain
(Bulgaria). It was found in associations with the next dominant species: Hyalosphenia papilio, N. galeata,
N. speciosa, N. penardiana, Argynnia dentistoma, A. vitraea, Q. symmetrica and Cyphoderia ampulla.
The habitats, where N. golemanskyi occurs, are characterized by constant high moisture, high contents of
organic matter and acid reaction of the environment (pH between 4.9 and 5.6).
