Guepinia helvelloides is a saprobe mushroom that grows gregarious or bushy, in humid areas and in soils rich in humus, in coniferous woods and often on woody residues; it occurs in the period between summer and autumn.
In N. Macedonia, it occurs in autumn (September – October) in the higher sections of Sar Mt, at an altitude between 1,500 and 1,800 m. Both sites are either within or in the vicinity of the two best-developed spruce communities in the country. They are affiliated to HD Annex 1: 9410: Acidophilous Picea forests of the montane to alpine levels (Vaccinio-Piceetea). Jelak locality, where the largest number of fruit bodies have been observed, encompasses a well-developed spruce community (ass. Piceetum abietis scardicum Em 1986) whereas the other site is near the confluence of the Adzina Reka into the Radika river, and it is represented by a grove of birch with individual spruce trees. The latter site is about a hundred meters away from the southern complex of spruce forest in the Adzina Reka river valley. Individual spruce trees have also been registered in Malesevo Mts (at the site Murite), in the eastern part of the country, close to the Bulgarian border. It is worth underlining that in view of its geographic position, the territory of N. Macedonia is the southern boundary of spruce forest European areal of distribution.
