Description

Sori on roots forming elongate often branched-digitate dark brown galls to 15 mm long.

Spores globose or subglobose, (12.0–) 13.5–23.0 (–28.0) µm diam., solitary or sometimes in pairs and then often with flattened contact sides, light yellow to yellowish brown; wall 2-layered, very variable in thickness and ornamentation, (1–) 2–4 (–10) µm thick, often with well-developed warts and tubercles, sometimes smooth.

Spore germination resulting in spores becoming 4-celled by 2 perpendicular divisions, forming 4 basidial cells that remain in the spores; each cell producing a long thin pedicel on which 1–4 terminal falcate or looped basidiospores are produced; on solid media the basidial cells producing branched hyphae.

Comments

Walker (2007) noted the presence of spiral hyphal coils in the gall cells of some Australian specimens. It is noteworthy that E. casparyana was first detected in Australia on plants of Juncus planifolius growing as weeds in plant pots containing Isolepis infected with E. seminarii (Walker, 2007).
