The naked basidia relatives ( Exobasidiaceae ) are a family of smut fungi (Ustilaginomycotina) and like all smut fungi are parasites of plants .

features

The naked basidia relatives do not develop any fruiting bodies , or they are sunk into the plant tissue. Plant galls are often created by hypertrophy . The hyphae system is monomitic , the hyphae run through the host tissue inter- and extracellularly. Buckles can be present. Sometimes haustoria are formed. The fruit layer is whitish and is formed under the leaf surface. Hyphae protrude from the stomata or break through the cuticle . The basidia are cylindrical to club-shaped or urn-shaped with a different number of sterigms . The basidiospores are released actively, rarely passively. They are hyaline , small, thin-walled, club-shaped to cylindrical and often curved. When ripe, they are septate with a conspicuous, off-axis, tapering (apiculate) hilum . When germinating, they form rod-shaped, spindle-shaped or thread-shaped conidia .

ecology

Nude basid relatives are common, especially in temperate areas. The species live biotrophically and parasitically and produce plant galls on leaves, especially on heather plants . Some species live on economically important plants, such as Exobasidium japonicum on azalea or Exobasidium vexans and Exobasidium camelliae on tea and can cause significant crop failure.

Systematics

Joseph Schröter described the family in 1888. The type genus is Exobasidium . They are the sister group of the Graphiolaceae , which parasitize on palm trees. The following genera belong to the family of the naked basid relatives:

• Austrobasidium
• Endobasidium
• Exobasidium
• Laurobasidium
• Muribasidiospora
