Whilst surveying some heathland in Dorset I occasionally noticed some small mushrooms growing on the stems of Ling (Calluna vulgaris).
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
It does say that it grows on pine needles,conifer litter and also dead heather.
I have found it on heather as well.
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.
Will change it in my book for any future finds.
