Fissidens littlei (Williams) Grout

Family: Fissidentaceae

Status: Native

Synonyms:
Moenkemeyera littlei Williams

Fissidens littlei is an extraordinarily rare and minute moss found only in a single locality in south central New Mexico. It has no limbidium, although the marginal cells are somewhat lighter in color than the central laminal cells and transversely elongate. The margins are entire but the cells at the margin bulge and give the appearance of undulation at high power. The costa fails a few cells short of the apiculus. The lamina is one stratose and the cells are irregularly hexagonal. Fissidens littlei is the only moss that has rare plant status with the New Mexico Rare Plant Technical Council.
