Anomalomyces yakirrae R.G. Shivas, M. Lutz, McTaggart & Vánky

Description

Sori in some ovaries of an inflorescence, globose to subglobose, 2.5-3.5 mm diam., covered by a thin olivaceous brown peridium, at maturity rupturing irregularly to expose the dark brown semi-agglutinated to granular-powdery mass of spore balls.

Spore balls subglobose, ovoid, ellipsoidal to subpolyhedrally irregular, 30-125 × 25-70 µm, dark reddish brown or opaque, composed of tens to hundreds of tightly packed spores that separate under moderate pressure, covered in a dark reddish brown amorphous layer 2.5-3.5 µm thick.

Spores subglobose, broadly ellipsoidal to subpolyhedrally irregular, 8.5-12.0 × 7-10 µm, pale reddish brown; wall smooth, 0.5-1.0 µm thick; outer spores with remnants of spore ball coating attached.
