Coniochaeta Extramundana, with a Synopsis of OtherConiochaetaSpecies

Coniochaeta prunicola — first record for Slovakia and Europe

“…The literature gives evidence that although the asci and ascospores are indicative, the setae remain the definitive characteristic for classification of the most Coniochaeta species. The literature gives evidence, that although the asci and ascospores are indicative, the setae, in most cases with brown to black rigid hairs, straight or bent, unbranched with a sharp apex scattered over perithecial walls or concentrated in their upper parts remain the definitive characteristic for classification of the most Coniochaeta species [5]. Some of species have been referred as lacking setae [17].…”

“…The identification was performed according to morphological keys [10,[14][15][16][17] and other reference guides [4][5][6]12]. …”

“…The most distinctive morphological features are germ-slits in ascospores, differentiating these fungi from Sordariaceae and its phialidic anamorphs belonging to Lecythophora [4]. Coniochaetaceae are characterized by dark brown to black ascocarps, ostiolate peridia with or without setae, and dark brown, discoid, nearly globose or ellipsoidal ascospores [5,6].…”

New record of the fungus Coniochaeta prunicola on peaches from Slovakia

“…Coniochaetaceae are characterized by dark brown to black ascocarps with an ostiolate peridium that may or may not be setose, and forming the dark brown, discoid, nearly globose or ellipsoidal ascospores which are variable in shape and size but most commonly ellipsoid to fusoid or nearly globose, 1-celled, smooth, brown to black, with a distinct germ slit (Mahoney & LaFavre 1981;Hawksworth & Yip 1981;Hanlin 1990;Weber 2002). The genus Coniochaeta (Sacc.)…”

“…The genus Coniochaeta (Sacc.) Cooke is generally described as a large and highly diversified ascomycetous genus with non-stromatic, globose or subglobose perithecia with a short neck and usually broad ostiole (Mahoney & LaFavre 1981;Asgari & Zare 2006).…”
