Ecology. Pholiota adiposa grows as a parasite on stems and branches of living trees, later also as a saproparasite or saprophyte on fallen stems and dead wood. It typically grows several meters above the ground, contrary to the related species Pholiota jahnii that typically grows on stem bases, roots and wood bSorbus aucuparia, Quercus sp., Tilia cordata, Tilia sp. and also Abies alba a Picea abiesuried in the ground. The most frequent substrate is wood of Fagus sylvatica. In the PRM herbarium (National Museum Praha) finds from the following tree species are represented also: Aesculus hippocastanum, Acer pseudoplatanus, Acer platanoides, Celtis occidentalis, Juglans regia, Malus pumila, Populus tremula, Sorbus aucuparia, Quercus sp., Tilia cordata, Tilia sp. and also Abies alba a Picea abies. Jacobsson mentions also one find on Betula.
Pholiota limonella, discovered for Europe by Jacobsson (1987), looks very similar and differs from P. adiposa by its slightly smaller, especially narrower spores [6.5-9(-10) x 4-5.3(-5.8) /im; Holec 1997a] and partly also by substrate preference (mostly Alnus, Betula but also Picea, Abies and various deciduous trees, see Jacobsson 1987, 1990; Holec 1997a). Reliable identification of P. limonella is possible only on the basis of spore width. It is necessary to measure at least 10 spores to establish the prevailing values (less than 6 /xm: P. limonella, more than 6 /xm ; P. adiposa and P. aurivella).
