This photograph was was taken at the site where this moss was found in the United States for the first time. We were on a Spring Bryophyte outing and visited a place where sterile plants of what turned out to be this taxon had been seen a month earlier by Paul Wilson and others. The fertile condition enabled these plants to be identified as Pleuridium mexicanum, new to the Untied States. (See The Bryologist 110(3):510-513. 2007). This is an overview image, the plants are the pale green pencil like stems to the left of the coin, mixed in with an upright green acrocarpous moss and a matted small dark liverwort.

The very small moss plants with narrow leaves and brown capsules at center and right are Ephemerum serratum. Other moss species are present at top and bottom. Photographed the same evening from a patch of 'moss turf' gathered on the West Coast Bryophyte Foray 2016.

The Ephemerum plants are the small ones with narrow leaves and brown capsules. Some Bryum plants are also visible as the larger greener moss. This was photographed at home as a piece of moss turf gathered intact from the CYO Camp on Feb. 19th 2016

This is either Pleuridium subulatum or P. acuminatum. It is a small 'ephemeral' moss seen here in short moss turf. A small piece was harvested and this photograph was obtained the same day back at CYO camp but in situ on the turf piece. A second even smaller moss, Ephemerum serratum, can be seen with capsules at top center. The moss plants at bottom right with capsules may be Ephemerum and/or Phascum cuspidatum.

This distinctive Hawaiian endemic aquatic moss has a superficial resemblance to Fontinalis, but is not closely related. It is seen here in its native habitat under shallow water on the bed of a flowing stream in a forest opening at about 4,000 feet elevation on Kauai.
