Importance and distribution
Taeniolella includes lichenicolous species which occur on a wide range of lichens and grow on thalli and fruiting bodies (mostly apothecia) without causing harm to the host. A few species are pathogenic and cause damages of the thalli or discolorations and necroses (Ertz et al. 2016). Some species also induce the formation of distinct galls (Heuchert et al. 2018).
Taeniolella produces Chromone derivatives, R - and S – taeniolin (Intaraudom et al. 2021). They can also produce important compounds and extracellular enzymes such as cellulase, lipase, protease amongst others (Thirunavukkarasu et al. 2017). Taeniolella can also produce black pigment and Melanins (Melo et al. 2018).
There are 68 Taeniolella epithets in Index Fungorum (2022), but eight species have been transferred to Cladophialophora, Corynespora, Septonema, Stanjehughesia, Sterigmatobotrys, Taeniolina and Talpapellis. Taeniolella comprises 60 species. Taeniolella is known from numerous plant families such as Agyriaceae, Altingiaceae, Arthoniaceae, Asparagaceae, Chrysotrichaceae, Cladoniaceae, Fagaceae, Hymeneliaceae, Lecanoraceae, Myricaceae, Pertusariaceae, Poaceae, Sapindaceae and Tephromelataceae. Taeniolella has been reported from Africa (Northern Provinces), Asia (India, China, Russian Federation), Europe (Austria, Denmark, France, United Kingdom, Greenland, Luxembourg, Poland, Sweden), North America (Canada, the United States), South America (Peru).
