This is part of a set of changes published by Grusz & Windham in 2013, separating the myriopterid ferns from the broadly defined genus Cheilanthes. These changes have been adopted by CalFlora for M. clevelandii, M. cooperae, M. covillei, M. gracilis, M. gracilima, M. intertexta, M. newberryi, M. parryi, M. viscida, and M. wootonii. However, Go Botany has not updated its taxonomy since the publication of Flora Novae-Angliae, and hence has not yet adopted the transfer of Cheilanthes lanosa to M. lanosa.
Weakley's flora (2015) for the southeastern U.S. has adopted M. alabamensis, M. gracilis, M. lanosa, M. microphylla, M. rufa, and M. tomentosa.

Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
