Taxonomy
It was described as new to science in 2014 and classified as Cortinarius pallidirimosus from specimens collected in Finland. It was placed in the subgenus Phlegmacium of the large mushroom genus Cortinarius.[2]
In 2022 the species was transferred from Cortinarius and reclassified as Thaxterogaster pallidirimosus based on genomic data.[3]
Description
Fruitbodies are distinguished in the field by their cream-coloroured caps with hygrophanous streaks, the honey-like odor of the flesh, and the association with birch.[2]
Etymology
The specific epithet pallidirimosus refers to the pale, streaked cap. Thaxterogaster caesiophylloides is a closely related sister species.[2]
Habitat and distribution
The fungus is found throughout Fennoscandia, in Russia, and in Oregon (United States). It fruits on the ground singly or in small groups in boreal forest, mesic forest, and mixed forests with birch.[2]
