Importance and distribution
Scirrhia species are associated with leaf spot. There are 45 Scirrhia epithets in Index Fungorum (2022), but several species have been transferred to other genera such as Arthrinium, Delphinella, Dothidea, Dothidella, Dothistroma, Lecanosticta, Mycosphaerella, Phyllachora, Placostroma and Telimenella. Scirrhia comprises 24 species known on a wide range of plants such as Abies alba (Pinaceae), Agrostis sp. (Poaceae), Athyrium sp. (Athyriaceae), Bambusa gracilis (Poaceae), Carex sp. (Cyperaceae), Equisetum sp. (Equisetaceae), Phyllostachys bambusoides (Poaceae), Pinus attenuata (Pinaceae), Pteridium aquilinum (Dennstaedtiaceae), Schizostachyum diffusum (Poaceae) and Thuja (Cupressaceae). Scirrhia is reported from several countries including Africa (Tanzania), Asia (Japan, Philippines), Europe (Poland, Sweden, United Kingdom), South America (Chile) and the United States (Florida, Hawaii, Texas). An effort to recollect species of Scirrhia is needed to increase knowledge regarding the diversity and taxonomy of the genus.
Quarantine significance
Scirrhia is of quarantine significance. Scirrhia pini is listed in the official pest report of Belgium (2008).
