Pylaisia selwynii (Kindberg) Crum, Steere & L.E. Anderson

Family: Pylaisiadelphaceae, formerly Hypnaceae

Status: Native

Synonyms:
None

Pylaisia selwynii grows on tree trunks-- in the Gila it can be found at least on the trunks of Quercus gambelii (Gambel Oak) and Juniperus deppeana (Alligator Juniper). Although it is a pleurocarp, mostly one sees the erect branches with tips that Crum and Anderson describe as "neatly curled." There are many quadrate alar cells along the margins, usually 15-25. The mid lamina cells are mostly up to about 6 times long as wide. The endostome of the capsule is adherent for part of its length to the exostome, and split into two sections usually in the free tips. Pylaisia selwynii is found at middle elevation in the Gila. We found Pylaisia selwynii on the 3 Rivers/Fall Creek trail north of Tularosa, NM, before we found it in the Gila. Those pix can be found on the Pylaisia selwynii 3 Rivers page.
