Most species of Leucoloma have a distinctive pale greenish color, apparently the result of their pluripapillose leaf cells. Papillae development is variable within the genus, and at least one West African species is epapillose. On the strength of its hyaline leaf limbidium Leucoloma has been aligned with Dicranoloma. However, its cellular areolation and erect capsules are more similar to those of the Holomitrium-complex. This relationship finds further support in the entire peristome teeth of L. tortellum.
