Phlegmacium is a subgenus of Cortinarius, which is the largest genus of agarics in Europe.

Phlegmacium species form mycorrhiza with coniferous or deciduous trees. They are widely distributed in Europe - from the oligotrophic spruce and pine forests of Fennoscandia to the calcareous holm oak forests in the mediterranean.

Like all Cortinarius species Phlegmacium have brownish ornamented spores and posesses a web-like cortina.

The combination of a sticky/viscid cap and a dry stipe is however unique to Phlegmacium.

The taxonomy and nomenclature of Phlegmacium is difficult. Species are mainly distinguished macroscopicaly. But spore morphology/size and other microscopical and chemical characters are also important.

Usually only collections including fruitbodies of all ages can be determined with some confidence. But with some practise and aid of keys and floras it becomes easier.

The aid of illustations is a great tool for determination, but few floras include a large number of Phlegmacia - hence this site!

Good luck!
