Status: Native
Synonyms:
Weissia verticillata Bridel
Eucladium verticillatum is most commonly found around springs on rocks. The cells at the base of the leaves are hyaline, rectangular and enlarged. Above the shoulder of the leaf the cells are chlorophyllose and much shorter to nearly quadrate near the apex. The leaf margins are plane, much like Gymnostomum aeruginosum, but the margin of Eucladium verticillatum has distinctive appearing prorate cells at the junction of the hyaline enlarged basal cells with the smaller chlorophyllose upper cells.
