Simuliomyces microsporus Lichtw., Mycologia 64: 180. 1972. ( Figs 56–60 )

Specimens examined: — COLOMBIA. SANTANDER: Tona; Río Agua Blanca, prepared from Simulium sp. Larvae, D. Baron, COL2–Tr5, Tr9; Tona, Río Seca o Chucurí, prepared from Simulium sp. larvae, D. Baron, COL6–Tr15.

Comments: — Simuliomyces microsporus is also a cosmopolitan species ( Lichtwardt et al. 2001) and behaves as an epiphyte, being attached to thalli of G enistellospora spp, Paramoebidium sp , Pennella spp , Smittium sp or Stipella sp. ( Manier 1955 a, Ingold 1967, Moss 1970, Valle et al. 2011). Colombian specimens were attached on thalli of Paramoebidium chattoni — (COL2–Tr5), Genistellospora sp. —(COL2–Tr7, Tr8 and Tr9) and Genistellospora homothallica — (COL6–Tr15). We observed specimens with ellipsoidal trichospores measuring 14–19 × 3.8–5 μm, collarless and biconical zygospores 31.5–36 × 6.5–7 μm with a zygosporophore about 17 × 6.5 μm ovoid, arising laterally from one of conjugating cells.

FIGURES 61–64. Stachylina lentica from Chironomidae . Various thalli with a small holdfast (arrow), and long-ellipsoidal trichospores on generative cells. Scale bar for Figs 56, 57 = 50 μm; for Figs 58 –64 = 20 μm.
