Anthoceros is a genus of hornworts in the family Anthocerotaceae. The genus is global in its distribution. Its name means 'flower horn', and refers to the characteristic horn-shaped sporophytes that all hornworts produce. The dark color of the spores is the easiest way to distinguish Anthoceros from the related genus Phaeoceros, which produces spores that are yellow. Carolus Linnaeus Carl Linnaeus, also known after his ennoblement as (help· info), and in English usually under the Latinized name Carolus Linnaeus (May 23, 1707 – January 10, 1778), the name with which his publications were signed, was a Swedish botanist and physician who laid the foundations for the modern scheme...

The genus is distinguished by having spores that are dark brown to black, a relatively frilly thallus when compared to Phaeoceros, and larger and more internal cavities than Phaeoceros. Thallus is an undifferentiated vegetative tissue (without specialization of function) of some non-mobile organisms, which were previously known as the thallophytes. ...

Only a few species are part of the European flora, of which three (Anthoceros punctatus, A. agrestis, Phaeoceros carolinianus) occur also in Switzerland (see http://www.nism.unizh.ch/map/map.htm for their distribution in Switzerland).
In the northern part of the country, Anthoceros agrestis and Phaeoceros carolinianus grow on sub-neutral, loamy or sandy soils on open ground, mainly in arable environments and here predominantly in cereal fields, and more rarely along paths and ditches (Bisang 1992).
