Discusión taxonómica
Lycopodiella contains about 40 species, of which three occur in Mexico. The genus as construed here is divided by some authors into three genera: Lycopodiella, Palhinhaea, and Pseudolycopodiella. The three Mexican Lycopodiellas are diverse, but details of sporangia, spores, and gametophytes suggest that they are closely allied.
