Many substrates

Yes, it is common on heather in moorland. I have once found it on a dead leaf of Sessile Oak (Quercus petraea) [though other small species of "Marasmius" are more frequent on this host]. In their recent monograph of this group, Antonin & Noordeloos state that though it is most common on conifer litter, it can occur on leaves of deciduous trees, crowberry, and other hosts as diverse as Cotton-grass and Twinflower (Linnaea).

The important thing, I think, is that the material must be very nutrient poor - less competition from other decomposers?

Everyone will be delighted to know that this species should now be called Gymnopus androsaceus. It has been shown not to be a Marasmius. Its lookalike, formerly Micromphale perforans, is also now a Gymnopus, so at least they are accepted as being closely related at last.
