Discussion

Few other mosses in the region are likely to be confused with Pireella pohlii other than P. cymbifolia. Plants of P. pohlii are usually irregularly pinnate, but may be simple if depauperate. The bases of stipe and stem leaves are variously rounded to almost auriculate; the alar cells are subquadrate or rhombic, few in number, and do not reach the margin. Pireella pohlii is found from central and northern Florida to Louisiana. Sporophytes of P. pohlii are known in the flora area from only one site in Florida.
