Lobothallia recedens (Taylor) A. Nordin, Savić & Tibell

A tiny member of the genus. It has a crustose thallus, usually richly covered by apothecia. There is a relatively great number of historical records on the species occurrence in the Czech Republic (see Vězda & Liška 1999). The oldest one refers to the name Aspicilia bohemica, later recognised as a synonym of L. recedens, which has been described from the former fortress Travná (Kellerberg) near the city of Kutná hora (Koerber 1855). The lichen usually overgrows periodically moistened siliceous rocks and boulders. In Europe, it has been recorded in various locations, from the Mediterranean to boreal zone. The only published recent Czech finding comes from the foothills of the Šumava Mts, where the species was found on periodically rinsed stones on a bank of the river Blanice (Vondrák & Palice 2004). The species distribution in the country is currently insufficiently known. However, it has probably considerably declined, although locally it may be overlooked.
