Genus name referring to the two-forked peristome teeth. Species name meaning transparent, presumably in reference. to the leaves as viewed under the microscope.
Commonly producing sporophytes in winter to early spring at lower elevations; at higher elevations sporophytes are rare but axillary gemmae are frequent.
With sporophytes, this species is distinctive; the suberect sporangia associated with the pale green, toothed leaves are reliable characters.
Forming bright, yellow-green to dark green turfs.
Dicranella palustris, found in similar habitats, has sporangia that are inclined and curved and the leaves are markedly squarrose (subsheathing at base then abruptly diverging outward). Comments: Western North American material is mainly D. flavescens (With.) Dixon, a species that shows a wide distribution independent of acidity of substratum. D. pellucidum, in the strict sense, is a calcicole. The plants tend to be bright yellow-green, compared to duller colours in D. flavescens. D. pellucidum is mainly subalpine, but may also be found at lower elevations, and occurs in calcium-rich sites. Many re-· searchers do not consider D. flavescens to be an independent species but treat it as within the variability of D. pellucidum.
If more than one illustration is available for a species (e.g., separate illustrations were provided for two subspecies) then links to the separate images will be provided below. Note that individual subspecies or varietal illustrations are not always available.
