Shivasia solida on Schoenus apogon. A. Embedded, stained, semi-thin section of a sorus (H.U.V. 17649), sh = sporogenous hyphae, sp = spore balls, p = peridium. B. Fungal cells of the peridium covering the sori, formed of thick-walled, sterile hyphae (H.U.V. 15059). C. Spore ball formation in sporogenous fungal layer on the surface of innermost floral organs, in U-shaped pockets, hand sectioned, stained with cotton blue in lactophenol (H.U.V. 15059). D–E. Young spores and spore balls covered by fungal cells of the young peridium, embedded in plastic, sectioned and stained with new fuchsin and cristal violet (H.U.V. 15059). F. Spore balls in different developmental stages, hand sectioned, stained with cotton blue in lactophenol (H.U.V. 15059). G–H. Spore germination in water, at room temperature, in 3–5 days (H.U.V. 15059). Bars: A = 100 μm, B–H = 10 μm.
