Pylaisia selwynii is usually found on the trunks of trees. Crum and Anderson describe the dry appearance as having "an abundance of erect branches, neatly curled when dry." In addition, there are many quadrate alar cells along the margin, up to about 30. The stem leaves (0.9mm to 1.2mm) are smaller than those of P. polyantha (usually 1.3mm or longer). The endostome segments of the capsule partially adhere to the exostome teeth and are split down the center. Several months after finding Pylaisia selwynii on the 3 Rivers Campground Trail, we discovered it on the Tadpole Ridge Trail in the Gila. The pix can be found at Pylaisia selwynii in the Gila.
