Specimens examined.

Site 4: slides BUL-4-1, BUL-4-5, BUL-4-7; site 7: slide BUL-7-6.

Notes.

We found this species associated with Leuctra hippopus (Kempny 1899) in two Bulgarian rivers and streams. The specimens examined had the typical characteristics of the species, including the straight trichospores measuring 47-56 × 5-7 µm in our collections, with generative cells 21-26 µm long and a supporting cell 6-8 µm length (Fig. 21 ). All the characters of trichospores and accompanying cells fit the description of the species ( Santamaria and Girbal 1998). Zygospores were not seen on this occasion. This species was described from Catalonia, Spain ( Santamaria and Girbal 1998, Valle and Santamaria 2005) and has been reported also from Norway ( White and Lichtwardt 2004), France ( Valle 2013b) and Italy ( Valle et al. 2014).
