Habitat: Rocky almost vertical road cut, northwest oriented, in mixed woods, quite damp and shady place, cretaceous clastic rock (flysh) bedrock, mixed with mosses, average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevations 520 m (1.700 feet), alpine phytogeographical region. - Substratum: cracked flysh rock. - Comment: Thalli dimensions, less shiny upper surface than C. conicum and grooves between 'cells' speak in favor of C. salebrosum. Nevertheless, the determination is not certain. These are fruiting female plants with terminal, stalked, conical receptacles. - Ref.: (1) Ian Atherton, Ed., Mosses and Liverworts of Britain and Ireland - a field guide, British Bryological Society (2010), p255.

This liverwort (of the 'complex thallose' type) was growing on mud banks along a small stream in open serpentine country near chaparral along Bottle Rock Road, Lake County, California, on March 28th 2012. This piece was collected and photographed (still in in its micro-habitat) at at my house later. Thanks to Martin Hutten and Dan Norris for the identification.
