Phlegmacium balteatialutaceum is a species of mushroom-forming fungus in the family Cortinariaceae. Originally described in 2014 as a member of the large genus Cortinarius, it was reclassified in 2022 based on genomic data. The fungus is characterised by its pale brown cap with a whitish margin that darkens with age, notched gills that progress from pale brownish grey to pale brown, and a whitish club-shaped stem. Found in Fennoscandia, it grows in association with birch trees in subalpine birch forests and middle to northern boreal forests near oceans, typically fruiting from mid-August to mid-September.

“Phlegmacium balteatialutaceum” is worth following because a concise public description often conceals a longer documentary argument. Here, Phlegmacium, balteatialutaceum and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 24, 2025. The linked authority identifier is Q20051072. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2014, 2022 and 2009.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
