Note.

This species was obtained from the hindgut lining of Simuliidae larvae. Most of the observed specimens of S. microsporus were attached to thalli of both Genistellospora homothallica (Fig. 2 ) and Paramoebidium chattoni . All the individuals had trichospores and one of the specimens showed also the typical type-I zygospores’ young (Fig. 2 ). All characteristics and measurements of Bulgarian S. microsporus match that of previous descriptions of the species in Europe ( Moss 1970; Valle 2004, White and Lichtwardt 2004). This species, discovered in the USA ( Lichtwardt 1972), has a sub-cosmopolitan distribution (see Lichtwardt et al. 2001), with a patchy distribution in the Northern Hemisphere and also Australia (Lichtwardt and Williams 1992).
