Pinecone Cap?

Growing on pine cone. the cap was probably 1-1.5cm across. Stem was very tough and cap wasn't very fragile. Spore print probably white but I did it on a glazed ceramic mat so it was hard to tell. Mycena sp.? Mycena inclinata? Same as this spotting? http://www.projectnoah.org/spottings/17159608 Strobilurus esculentus? S. tenacellus? Marasmius sp.? this similar-ish mushroom was growing probably a few hundred metres away although the stem seemed substantially thicker and mushroom generally bigger: http://www.projectnoah.org/spottings/23498029
