title: Rediscovery of Alnicola cholea (Cortinariaceae): taxonomic revision and description of its mycorrhiza with Polygonum viviparum (Polygonaceae).
abstract: Alnicola cholea, a little-known species so far reported only from the two original localities in the French Alps, is redefined here based on revision of herbarium materials and studies of recent field collections. A detailed morphological and anatomical description of fruit bodies of Alnicola cholea, including a discussion on its taxonomic status and distribution data is provided. Due to the unique combination of characters of Alnicola cholea within the genus, a new monospecific section is introduced for this species: Alnicola sect. Cholea, sect. nov. Mycorrhizal symbiosis of A. cholea with an arcticalpine plant Polygonum viviparum was observed in the Tatra Mountains (Poland). A description of these mycorrhizae is given, providing first detailed data on an identified herbaceous plant mycorrhiza.
