Diagnostic Notes **Sori** in some ovaries of an inflorescence, forming hard black globose to ovoid bodies, 1–2 (–3) mm long; when young covered by a silvery membrane. **Spores** in plane view (10–) 13–21 (–24) × 10–18 (–20) µm, rounded or angular, in side view flattened, 8–12 µm thick, light to dark olivaceous brown or reddish brown; wall 1.0–2.5 µm thick, often slightly thicker at the angles, with 1–4 low (but well-developed) internal swellings, lacking light-refractive areas; surface finely and densely verruculose; warts either not affecting the spore profile or giving it a slightly wavy or finely serrulate aspect; in SEM densely situated, rounded often confluent irregular warts are visible. **Spore germination** of _Anthracoidea_-type. **Anamorph**: _Crotalia cintractiae-variabilis_ Lehtola may be present. 3.
