Ascochyta is a genus of ascomycete fungi, containing several species that are pathogenic to plants, particularly cereal crops. The taxonomy of this genus is still incomplete. The genus was first described in 1830 by Marie-Anne Libert, who regarded the spores as minute asci and the cell contents as spherical spores. Numerous revisions to the members of the genus and its description were made for the next several years. Species that are plant pathogenic on cereals include, A. hordei, A. graminea, A. sorghi, A. tritici. Symptoms are usually elliptical spots that are initially chlorotic and later

Desmazierella is a genus of fungi in the family Sarcoscyphaceae. The genus was circumscribed in 1829 by Belgian mycologist Marie-Anne Libert in Ann. Sci. Nat. Paris Vol.17 on page 82 in 1829 with the type, D. acicola, as the sole species. The genus name of Desmazierella is in honour of Jean-Baptiste Henri Joseph Desmazières (1786 - 1862), a French apothacary and botanist, who lived in Lille.

Ascochyta pisi is a fungal plant pathogen that causes ascochyta blight on pea, causing lesions of stems, leaves, and pods. These same symptoms can also be caused by Ascochyta pinodes, and the two fungi are not easily distinguishable.

Discosia is a genus of plant pathogens in the family Sporocadaceae. It was published by Marie-Anne Libert in 1837. The genus was re-studied by Subramanian and Reddy (1974), who designated Discosia strobilina Lib. ex Sacc. as lectotype for the genus (Nag Raj 1993; Tanaka et al. 2011). Later, when Sphaeria artocreas Tode was transferred to the genus and combined under Discosia artocreas (Tode) Fr., the latter was chosen as lectotype of the genus (Fries 1849; Vanev 1991). Vanev (1991, 1992a, b, c, d) made a detailed taxonomic revision of the genus. On the basis of the location of the conidial

Ascochyta viciae is an ascomycete fungus species in the genus Ascochyta. Ascofuranone is an antibiotic first isolated from a strain of A. viciae in 1972; however, the identification of the strain is later revised as Acremonium sclerotigenum, and A. viciae cannot produce this antibiotic.

Diplocarpon rosae is a fungus that creates the rose black spot disease. Because it was observed by people of various countries around the same time (around 1830), the nomenclature for the fungus varied with about 25 different names. The asexual stage is now known to be Marssonina rosae, while the sexual and most common stage is known as Diplocarpon rosae. Diplocarpon rosae grows over seasons as mycelia, ascospores, and conidia in infected leaves and canes. In the spring during moist, humid conditions, ascospores and conidia are wind-borne and rain-splashed to newly emerging leaf tissue.

Sclerotinia sclerotiorum is a plant pathogenic fungus and can cause a disease called white mold if conditions are conducive. S. sclerotiorum can also be known as cottony rot, watery soft rot, stem rot, drop, crown rot and blossom blight. A key characteristic of this pathogen is its ability to produce black resting structures known as sclerotia and white fuzzy growths of mycelium on the plant it infects. These sclerotia give rise to a fruiting body in the spring that produces spores in a sac which is why fungi in this class are called sac fungi (Ascomycota). This pathogen can occur on many

Pseudopeziza medicaginis (P. medicaginis) is a fungal pathogen of alfalfa.
