Section Amictae A.H. Smith ex Maas G. comprises only two species in the Northern Hemisphere: M. amicta (Fr.) Quél. and M. subcaerulea (Peck) Sacc.

The two species can be separated on account of the spores which are pip-shaped and 4-5.5 µm in the former and globose to subglobose and 6-8 µm broad in the latter. Only M. amicta has been collected in Europe.
