As the species name suggests, Melanohalea laciniatula differs from other Melanohalea species in the presence of numerous small lobes on the thallus surface. Possibly, it can be mistaken for M. exasperatula, whose flattened isidia sometimes resemble tiny lobes.
It is a predominantly montane Mediterranean species, growing on the smooth bark of old deciduous trees in open moist forests. However, it also occurs even at lower elevations in humid areas of western and central Europe, often on solitary deciduous trees (e.g. ashes and maples) in avenues. According to historical data, the lichen used to occur sparsely in mountains of the Czech Republic, but recently it has been recorded only rarely in the Šumava Mts (Palice, unpublished).taxonomic classification: most frequented synonyms:Melanelia laciniatula
