Description

Sori in scattered ovaries, globose to ovoid, 2–4 (–5) mm long, covered by a smooth initially green, later brown peridium of host tissue, the entire sorus sometimes falling from the host or first the peridium rupturing irregularly exposing a granular black-brown mass of spore balls; hyphae intracellular.

Spore balls globose, subglobose, ovoid, elongate to irregular, (40–) 60–320 × (35–) 50–240 µm diam., dark brown, opaque, composed of numerous (several hundred) spores, united by sterile fungal cells and spore processes.

Spores globose, ovoid to irregular, slightly polyhedral, subhyaline to pale yellowish brown, 7–12 (–13) × 6.5–9.0 (–10) µm diam., usually with several ±well-developed extensions (spore processes) and remnants of the broken walls of the sterile cells; wall 0.5–0.7 µm thick, smooth.

Sterile cells empty at maturity, thin-walled (0.1–0.2 µm; measured by TEM), appearing as irregular meshes or wings on the spore surface when the spores are separated.

Spore germination with septate basidia producing lateral and terminal basidiospores.

Comments

Moesziomyces bullatus has sori that remain green until maturity. The protuberances on the spores are diagnostic.
