Baeomyces rufus is widespread and common throughout Scotland, preferring shaded, damp situations such as peat and soil in conifer plantations. It is also often found on the side of boulders in woodland or moorland situations. In heathland, it is often found where that has been recent disturbance or burning. BLS distribution map
Baeomyces rufus occurs in similar habitats as the similar-looking Dibaeus baeomyces and Icmadophila ericetorum. The crust of Dibaeus baeomyces, however, is smooth and carries scattered, coarse schizidia. In Icmadphila ericetorum the apothecia lack stalks.
