Helodium blandovii is a striking moss that is similar to the genus Thuidium. The cells are tall unipapillose on
the abaxial surface near the center or distal on the cells. Some of the papillae are nearly twice the height of the lamina. The costa sits in a sulcus in the lamina that can be so deep as to look like a sail. There are paraphyllia arising from both the leaf bases and the stems, so long and abundant that they appear matted. In New Mexico, H. blandovii is currently known from one collection at high elevation.
