The Botryosphaeriaceae are a family of sac fungi that alone make up the order Botryosphaeriales .
features
The fruiting bodies (Ascomata) are unilocular to multilocular and have multi-layered, dark brown walls. They stand individually or in groups and are often embedded in stroma tissue. The ascus wall has two layers (bitunicate) with a thick (inner) endotunica. The shape of the fruiting body is stalked or sessile, with a well-developed apical chamber. Hyaline , septate pseudoparaphyses occur. The ascospores are hyaline or pigmented and can be septate. The shape is ellipsoidal to ovoid. A mucus appendage or sheath may be present.
The anamorphs form monocular to multilocular pycnidia , which are often embedded in stroma tissue. The conidia-forming cells are hyaline and phialidic , the conidia are hyaline or pigmented, thin or thick-walled, which in some species have mucous sheaths or appendages.
Systematics
Eriksson (2006) still led the family as "Dothideomycetes et Chaetothyriomycetes incertae sedis ": Schoch et al. put the family in their own order Botryosphaeriales in the same year, which is not assigned to any subclass within the Dothidiomycetes.
According to Eriksson's list, the following genera belong to the family:
- Amarenomyces
- Auerswaldiella
- Botryosphaeria
- Dothidotthia
-
Guignardia
- Guignardia bidwellii : pathogen causing black rot in the vine
- Leptoguignardia
- Sivanesania
