We consider the moduli space M g, n of Riemann surfaces of genus g≥ 0 with n≥ 1 ordered and directed marked points. For d≥ 2 g+ n− 1 we show that M g, n is homotopy equivalent to a component of the simplicial Hurwitz space Hur Δ (S d geo) associated with the partially multiplicative quandle S d geo. As an application, we give a new proof of the Mumford conjecture on the stable rational cohomology of moduli spaces of Riemann surfaces. We also provide a combinatorial model for the infinite loop space Ω∞− 2 MTSO (2) of Hurwitz flavour.
