Disciotis venosa (Pers.) Arnould

Disciotis is a genus of fungi in the family Morchellaceae. Members of this family, characterized by their cup- or bowl-shaped apothecia, have a widespread distribution, especially in northern temperate regions.[1]

Description

Disciotis has a cupulate (cup-shaped) pileus with vein-like hymenial folds and a small to non-existent stipe.[2]

Species

The type species is Disciotis venosa, originally described as Peziza venosa by Christian Hendrik Persoon in 1801. Other species described in the genus include:

  • Disciotis ferruginascens Boud. (
  • Disciotis maturescens Boud. (1891)
  • Disciotis rufescens R. Heim (1934)

It has been suggested that these species (and variants not listed above) all represent a single, morphologically variable species.[3]

There is confusion about the names but the genus also includes these species:
