Eriocortex eriocauli R.G. Shivas, Vánky, M.D. Barrett & M. Lutz


Sori in some capsules of an inflorescence, filling them with a black, granular-powdery mass of spore balls, replacing the ovaries, liberated by the opening of the capsules but hidden by the floral envelopes.

Spore balls globose, ovoid, broadly ellipsoidal, subpolyhedrally, rarely triangularly irregular, 40-120 × 45-145 µm, dark reddish brown, subopaque, permanent, breaking by hard pressure, composed of several tens to some hundreds of tightly packed, easily separating spores, and a thin, dark, hard, fungal cortex.

Spores globose, ellipsoidal to rounded subpolyhedrally irregular, 8-12 × 8.5-14 µm, pale yellowish brown; wall even, thin, c. 0.5 µm thick, smooth.

Cortex 2-4 µm thick, dark reddish brown, composed of tightly packed, interwoven and conglutinated structure of short or elongated, irregular, often bent or even ramifying sterile fungal cells, 1.5-2.5 µm wide, 8-20 µm long; wall slightly uneven, 0.5-1 µm thick.

Sterile cells absent.
