The wrinkled scabies (Rhytismatales) are an order of the hose fungi . The species live parasitically on plants.

features

The sexual forms ( teleomorphs ) form apothecia as fruiting bodies , the excipulum of which is reduced. The fruiting body develops within the stroma , which in turn is sunk into the host tissue. The hymenium escapes into the open as host and fungal tissue with longitudinal slits burst open. In Cudonia and Spathularia , the fruiting bodies develop on the ground and morphologically resemble those of the Helotiales . The asci are thin-walled, have an undifferentiated apex and are not amyloid . The ascospores often have a gelatinous sheath or appendages.

The asexual forms ( anamorphic ) are mostly Leptostroma -like: The conidia are formed on constantly multiplying conidiogenic cells.

Systematics

The genre and family descriptions are artificial in many areas, but sufficient studies for a new classification are still pending. There are four families and 22 genera that are not assigned to any family (with selected genera and species):

• Bark scab relatives (Ascodichaenaceae) with 3 genera
  • Ascodichaena
    • Beech bark scab ( Ascodichaena rugosa )
• Cryptomycetaceae with 4 genera
  • Cryptomyces
• Ling circuit related (Cudoniaceae) with 2 genera
  • Circles ( Cudonia )
  • Spatulas ( Spathularia )
• Wrinkled scab relatives (Rhytismataceae) with 43 genera
  • Cleft lips ( lophodermium )
  • Shield cup blanks ( Colpoma )
    • Oak shield cupling ( Colpoma quercinum )
  • Crack scabs? ( Lirula )
  • Meloderma
  • Nematococcomyces
  • Wrinkled scabs ( Rhytisma )
    • Maple scab ( Rhytisma acerinum )
  • Terriera
  • Triblidiopsis
  • Vladracula
