The naked basidia ( Exobasidium ) are a genus of fungi from the family of the naked basidia relatives (Exobasidiaceae).
features
Macroscopic features
Naked basidia are parasites on the heather family (Ericaceae). Some species parasitize leaves, some annual shoots and others the entire plant (systemic infection). Infested leaves and shoots are often puffed up or misshapen and pale or mostly red in color.
Microscopic features
The hyphae are intracellular and have no buckles. The underside of leaves is covered with hymenium, which rarely affects whole shoots. The spores are elliptical or cylindrical, usually curved, hyaline, smooth, inamyloid and have 1–3 septa at maturity .
