The genus was previously part of the broader genus Strigula until a 2020 revision recognized Dichoporis as a distinct lineage, characterized by one-celled ascospores that may pinch at the septum, macroconidia with gelatinous tails, and minute branched paraphyses inside the perithecia. All species form symbiotic relationships with green algae of the genus Trentpohlia, which provides the photosynthetic component of the lichen....read more on Wikipedia.
