Genus/species: Pseudopezicula tracheiphila
- Cell: numerous, small, gelatinous apothecia containing paraphyses and asci with 4 binucleate spores. Conidiogeneous cell are monophialidic and lageniform with well-defined, but thin-walled collarettes.
- Colony: Malt agar: the anamorph may be formed with hyaline, septate, short conidiophores that are coarser than vegetative hyphae.
- Spore: conidia (asexual) and ascospores (sexual)
- Zygote: primordia in apothecia
- Ascus: apothecia

Found on grape leaves associated with vascular tissue. Initially yellow on white and bright red to reddish brown on red cultivars, a reddish brown necrosis develops in the center of the lesion (known as Rotbrenner).
Found in warm vineyards with stony soil
The anamorph may be formed with hyaline, septate, short conidiosphores. It has conidiogeneous cells.
