NOTES: Niesslia kapitiana is characterised by the small size and hooked nature of the setae and by the scattered arrangement of the setae over the ascomatal surface. The ascospores are also unusual in being spinulose, 0–1 septate, 13–21.5 × 4–5.5 µm and surrounded by a gelatinous sheath. No reported species of Niesslia have ascospores of this size and morphology. Niesslia vaginata (current material) has ascospores that are finely verrucose, and surrounded by a gelatinous sheath. However, in that species the ascospores are 9.5–13 × 2–3 µm, and the setae are straight and 30–64 µm long and 8.5–16 µm wide at the base.
