Bartramia ithyphylla Bridel

Family: Bartramiaceae

Status: Native

Synonyms:
Bartramia breviseta Lindb.
Bartramia ithyphylla Brid. var. breviseta (Lindb.) Kindb.
Bartramia ithyphylla Brid. var. fragilifolia Cardot & Thér.
Bartramia ithyphylla Brid. var. strigosa (Wahlenb.) Hartm.

Bartramia ithyphylla can be quite inconspicuous unless it bears its characteristically nearly spherical sporophytes that look like staring eyes. The nearly opaque distal leaf is very long attenuate, nearly grass-like, with the costa disappearing into the apex. The base of the leaf is translucent hyaline to slightly brownish or orange and sheaths the stem. There is a definite shoulder on most of the leaves, where there are rectangular cells that are frequently bulging. The mid-laminal cells are prorate distally. The distal lamina is 2-3 stratose and makes a strange appearing bistratose cross section with prorate cells visible all along the margin. We found Bartramia ithyphylla at about 11,000 feet elevation hiding among large boulders in mixed conifer forest where it received no direct sunlight.
