Abstract
In the past the genus Microlejeunea Stephani (1888) has often been regarded as a subgenus of Lejeunea Libert (1820). Lejeunea bischlerae Thiers (1997) was described using this concept. However, recent molecular studies (e.g. Wilson et al. 2004) resolve Microlejeunea as a sister of Lejeunea. If this concept is followed, a new combination is needed.
