Conocephalum conicum, also known as the great scented liverwort or snakeskin liverwort, is a liverwort species in the genus Conocephalum.[1]C. conicum is part of the Conocephalum conicum complex, which includes several cryptic species.[2] The name C. conicum refers to the cone-shaped archegoniophore, which bear sporangia.[3]
C. conicum is one of the most common liverworts in northern hemisphere[4] and is widely distributed throughout Canada.[5]
C. conicum is found in open woodlands, sandy banks, wet rocks or cliffs and moist soils[3] and is strongly associated with calcareous substrates.[6]
Morphologyedit
Thalliedit
C. conicum is the largest of the thalloid liverworts, growing up to 20 cm long.[5]
The thalli can grow to 17 mm wide. The thalli are very strong-smelling, with purplish margins; a dark green, leathery surface; flat and smooth. There is a set of lines running along the thalli's surface. The air pores, which are found between the lines, are more conspicuous. trans-Methyl cinnamate is a major doriferous component from two populations of this liverwort, but has not been identified from other populations.[7]
Reproductive structuresedit
Male plants bear unstalked, terminal cushions. Female plants have terminal conical receptacles on stalks, which are shortly lobed.[8]
Relationships with fungiedit
C. conicum has been associated with some species of fungi. These fungi form a highly branched mycelium outside of the plant which then colonize the outside of the rhizoids and pass into the gametophyte.[9]
