Sori (see Fineran, 1971: 496, fig. 2) as root galls, simple, digitate or much branching, ca. 1-2 ´ 3-10 mm, filled with intracellularly developing spores. Spores (Figs. 14, 15) globose or subglobose, solitary, rarely in pairs, sometimes with a short hyphal appendage, 10-16 ´ 10-16 (-17) µm, subhyaline to yellow; wall two-layered, inner layer equal, c. 0.8 µm thick, outer layer equal or unequal, very variable in thickness, usually 1-2 (-2.5) µm thick, in some spores apparently absent, in others 2.5-5 µm wide, smooth or slightly undulate, in SEM smooth to irregularly roughened.

Sori gallae radicis, simplices, digitati vel multiramosi, cca. 1-2 ´ 3-10 mm, sporis intracellulariter evolutis impleti. Sporae globosae vel subglobosae, solitariae, raro binae, aliquando appendage brevi, hyphali, 10-16 ´ 10-16 (-17) µm, subhyalinae usque flavae; pariete bistratoso, strato interno aequali, cca. 0,8 µm crasso, strato externo aequali vel non aequali, crassitudine valde vario, plerumque 1-2 (-2,5) µm crasso, in sporis nonnullis conspicue absenni, in aliis 2,5-5 µm crasso, levi vel parum undulato, sub SEM levi usque irregulariter scabroso.

Etymology: casparyanella, diminutive of casparyana, allusion to the much smaller spores of this species, than those of Entorrhiza casparyana.

Typus in matrice Juncus gregiflorus L. Johnson (Juncaceae), New Zealand, South Island, Canterbury, between Pigeon Bay and Port Levy, IX. 1970, leg. J. M. Fineran. Holotypus in Herbario Ustil. Vánky (HUV 14794!), isotypus in CANU 16006 (sub. E. casparyana).
