éphémère asymétrique

Ephemerum cohaerens is a tiny, ephemeral moss in the family Pottiaceae (or Ephemeraceae, according to some classification schemes) with a distribution across Europe and North America. The genus Ephemerum consists of minute mosses that lack a persistent leafy gametophyte stage visible to the naked eye; instead, the dominant visible structure is the sporophyte, with the diminutive gametophytes bearing single stalked capsules close to the soil surface. E. cohaerens grows on moist, disturbed, bare soil in arable fields, garden beds, paths, and river margins. These ephemeral mosses are early colonizers of open mineral soils, completing their life cycle rapidly and then disappearing. They rely on conditions with minimal competition from taller vegetation. The species has not been formally evaluated by the IUCN for conservation status, reflecting the limited demographic data available for many bryophyte species. Ephemeral mosses of arable habitats are of some conservation interest in Europe, where intensification of agriculture has reduced the extent and frequency of winter-fallow bare soil conditions that these species require.
