Megaspora rimisorediata

Megaspora rimisorediata is a species of crustose lichen in the family Megasporaceae. Found in Iran, it was described as a new species in 2011. It is distinguished by its distinctive network of dark blue-green powdery granules that develop along cracks in the lichen's surface, which gives the species its name meaning 'crack-sorediate'. The lichen grows primarily on oak bark in mountainous steppe regions across northern Iran, where it appears to grow better during wetter winter months than in summer.
