An unknown orange gilled mushroom growing on our pine tree stump. No idea what it is. Grew in clumps on the same stump last year, March 2013 and this year February 2014. Also some coming up further away from the stump, where old pine roots were growing. The photos are from 2013 and show different stages of development. One 2014 cap reached 15-20 cm in diameter before we found it growing behind foliage and removed it. Can someone identify as per toxicity?
