Fig. 17 Specimen examined. site 12: slides BUL-12-1; BUL-12-4. Notes. This species was previously known from Costa Rica ( Lichtwardt1997 ), Spain ( Valle and Santamaria 2004 ), Dominican Republic (Valle and Cafaro, 2010) and Mexico ( Valle et al. 2011 ) in the tract of Simuliidae and Chironomidae . Bulgarian specimens were associated with Chironomidae midges ( Chironomus sp.). They had cylindrical-elongated trichospores measuring 16-19 x 3-4 µm , with a short collar about 2.5 µm , slightly flared outwards. The thallus is branched at the base, with verticillate apical branching (Fig. 17 ). Each fertile branch has 4-6 generative cells. Specimens from Bulgaria resemble most of those described from Spain.
