A saxicolous lichen, similar to the species A. conoidea and A. salweyi. However, A. subglobosa differs in the character of involucrellum and ascospores size. Usually, it is reported from shaded or partly shaded calcareous rocks (limestones, calcareous sandstones, schists). It is a rare lichen, known only from a few European localities. It was described from the Czech Republic, from limestones in the vicinity of the cave Na Špičáku in the Hrubý Jeseník Mts. Besides, it has been later found on calcareous sandstone near Vsetín. There is no report on its current occurrence in the country, but very likely it still persists on the two mentioned localities.
