The Gnomoniaceae form a family from the order of the Diaporthales .
features
According to Monod (1983) the Gnomoniaceae are characterized by sunken fruiting bodies ( Ascomata ) individually without stroma or in aggregates combined in reduced prosenchymatic stroma in herbaceous plants, especially in leaves and stem, but also in wood. The Ascomata are generally softly structured, thin-walled and prosenchymatic with a central or lateral protuberance. The asci can have a pronounced apical ring with generally small ascospores that are less than 25 µm long, which can be septate or unseptate. The anamorphs are acervular or pycnidial , mostly with a wide opening and phialidic mostly unseptated conidia .
ecology
Gnomoniace are mostly found on hardwood trees , but also on conifers such as the anamorphic genus Sirococcus. Several diseases have been described that cause them, but which have also been described as endophytes.
Genera (selection)
- Gnomonia : may not be monophyletic
- Gnomoniella : pathogen causing leaf tan in u. a. Hornbeam and hazelnut
- Apiognomonia : causative agent of leaf tanning in oak , beech and plane tree
- Cryptodiaporthe : Cryptodiaporthe populea is the causative agent of the bark blight of the poplar
- Cryptosporella
-
Pleuroceras :
- Pleuroceras pseudoplatani : Pathogen causing the sycamore leaf tan
- Sirococcus : only the anamorphic is known. Call Anthracnose at z. B. dogwood and butternut .
Mazzantia has recently been added to the Diaporthaceae .
