Fig. 16 Specimens examined. Site 2: slide BUL-2-9; Site 11: slides BUL-11-1 (zygo.), BUL-11-2, BUL-11-3. Notes. This species was found on the hindgut lining of Baetidae hosts ( Baetis rhodani Pictet, Baetis melanonyx (Pictet) and B. alpinus (Pictet). The species seems to have a cosmopolitan distribution, at least in the Northern Hemisphere ( Lichtwardt et al. 2001 ). In Europe, the species is common, with records from France, where it was originally described under the name of Genistella ramosa ( Leger and Gauthier 1932) ( Pouzar 1972 ), from United Kingdom ( Moss 1979 ), Switzerland ( Lichtwardt 1986 ), Spain ( Valle and Santamaria 2002 ), Norway ( White and Lichtwardt 2004 ), Sweden ( Lichtwardt 1984 ), Portugal ( Valle 2013a ) and Italy ( Valle et al. 2013 ). Legeriomyces ramosus has been reported also from India ( Misra and Tiwari 2008 ), China ( Strongman et al. 2010 ), from several localities in USA ( Lichtwardt 1986 ) and Canada ( Strongman 2010 ). Bulgarian specimens have, as is usual in this species, a broad range of trichospore variability, measuring 30-40 x 7-8.5 µm , with two appendages differing in length. Zygospores measure 50-61 x 9-12 µm in our collections (Fig. 16 ). Figures 11-16.
