Spores when mature solitary, globose, subglobose to ellipsoidal, 4.5–5.5 × 4.5–5.0 µm, yellowish brown; wall uniformly c. 0.5 µm thick, minutely verruculose; spore profile smooth.

Sterile cells mostly in chains to 250 µm long; individual cells of variable shape and size, globose, ellipsoidal, usually irregular with two flattened sides, 5–12 (–15) µm long, hyaline, occasionally subhyaline with pale yellow tint; contents homogeneous; wall 0.5–1.0 µm thick, smooth.
