Notes.

Species were obtained from the hindgut lining of Leuctridae nymphs (mainly Leuctra hippopus ). We found several thalli, most of them producing trichospores and one also bearing helicoidal zygospores, formed homothallically, measuring 25-27 × 5.5-6.5 µm, growing on a fusiform zygosporophore measuring 20-23 × 7-8.5 µm, with a 3 µm long supporting cell and a sigmoid or reflexed intermediate cell about 20-24 µm long in the specimens seen (Fig. 24 View Figures 21–25 ). All the characteristics of spores and accompanying cells fit those of the specimens reported from other localities in Europe, including Spain ( Santamaria and Girbal 1998; Valle and Santamaria 2005), Norway ( White and Lichtwardt 2004); Italy ( Valle et al. 2013). Thallus has the characteristic basal cell (Fig. 25 View Figures 21–25 ) and lateral subsidiary branches.
