Remarks (public):The pale reddish hues and the lack of a citric yellow colouration on the pore surface in fresh condition are reliable field characters to separate A. confluens from A. ovinus. It tastes rather bitter and is less collected for consumption in Europe than A. ovinus which is collected very avidly. In North America. A. confluens is eagerly collected and is considered a good edible fungus with a distinctive taste and consistency.

Basidiocarps annual, centrally to laterally stipitate single or commonly confluent; stipe cream coloured to pinkish buff when fresh. glabrous, becoming salmon pink and rugose on drying, up to 8.5 cm long and 2 cm thick; pilei solitary to several on a branched stripe, circular to flabelliform or lobed and contorted, up to 11 cm wide and 3 cm thick; upper surface pinkish buff, becoming salmon pink on drying and storage in the herbarium, glabrous. azonate, smooth or becoming areolate, drying rugose. margin concolorous; pore surface cream coloured when fresh, slowly becoming salmon pink after drying, pores circular to angular. 3-5 per mm. with thick, fimbriate dissepiments that become thin and lacerate; context cream coloured, drying pale pinkish tan with a darker reddish zone above the tubes, soft and fleshy when fresh, drying fissile to hard and resinous, up to 2 cm thick near the stipe: tube layer becoming salmon pink on drying. up to 5 mm thick; often aromatic, odour pleasant; taste cabbage-like, becoming slightly bitter after a while.
Hyphal system monomitic; contextual hyphae hyaline in KOH, thin-walled, with frequent branching, with simple septa and also numerous and conspicuous clamps, highly irregular and variable in diam. 4-50 µm in diam, fragmenting and collapsing in sections from dried specimens and not readily separable; tramal hyphae, especially those in the subhymenial region, staining brightly in phloxine. thin-walled, with clamps, 3-5 µm in diam, with parallel arrangement and turning sharply at the apex to give rise to basidia; gloeoplerous hyphae also present. appearing refractive in Melzer's reagent and staining in phloxine and becoming reddish in KOH, contorted, with bulbous swellings, 4-18 µm in diam.
Cystidia or other sterile hymenial elements absent.
Basidia often bent sharply at the base, clavate. 4-sterigmate, 20-30 x 6-7.5 µm, with a basal clamp.
Basidiospores ovoid to ellipsoid, hyaline, weakly amyloid in Melzer's reagent. smooth, with slightly thickened walls, 4-5 x 2.5-3.5 µm.
Type of rot. Terrestrial, apparently not a wood-rotting fungus.
Cultural characteristics. Unknown.
Sexuality. Unknown.
Substrata. On the ground in conifer forests. It has a wide ecological range and occurs in pine forests as well as in spruce forests and mixed forests, quite rarely in broad leaved forests and then with unknown mycorrhizal partners.
Distribution. Slightly continental in its distribution and not known from Portugal. England. Denmark, western France, Belgium and northeastern Germany. In Norway lacking in the western part, north to Trondelag. in Sweden to Norrbotten. in Finland to Oulu. Previously common in Central Europe. but now rare and in Germany placed on the «red list». Common in Fennoscandia in naturally occurring coniferous forests. Circumboreal in coniferous forest ecosystems.
