## Abstract

Let $\mathcal{M}_g(\Gamma)$ be the stack of stable curves of genus $g$ with a given dual graph $\Gamma$ and let $\overline{\mathcal{M}}_g(\Gamma)$ be its closure in $\overline{\mathcal{M}}_g$. We consider the normalization of $\overline{\mathcal{M}}_g(\Gamma)$ in order to classify the residual orbifolds of the normalizations of the irreducible components of the locus in $\overline{\mathcal{M}}_g$ corresponding to curves with at least $3g - 4$ nodes.
