  In a recent article, Ayala et al. [Phys. Rev. D 73, 105009 (2006)] have
studied the dynamical generation of masses for fundamental fermions in strongly
coupled QED in the presence of weak magnetic fields. We argue that the results
and conclusions of the article are not reliable as they are subject to gauge
dependent artifacts resulting from an inconsistent truncation of the
Schwinger-Dyson equations.
