Synonyms: Preissia quadrata, Reboulia quadrata.
Narrow Mushroom-Headed Liverwort is a 'marchantioid' liverwort with a thick thallus and complex gametophore. Only the female archegonia are found on raised gametophores. The thallus often has a purple margin. Unlike Reboulia, this margin is flatter and does not curl back on itself. The pores on the thallus are raised and conspicuous.
Found over calcareous stone. Although there are few records for Maryland, this species would be expected in the mountains and piedmont.
There are 2 records in the project database.
