Status: valid. Holotype (visited): CH, Le Locle, tourbière du Grand Cachot (herb.J. Favre n° GK 9457, G). Host: Betula pendula or Pinus uncinata according to Favre (1948:133). Basionym: Alnicola scolecina var. fellea J. Favre, Beitr. Kryptogamenfl. Schweiz 10 (3): 214 (1948). = Alnicola fellea (J. Favre) Courtec., Doc. mycol. 16 (61): 48 (1985). = Naucoria fellea (J. Favre) Raithelh., Metrodiana 7 (2-3): 53 (1978). Notes: quite an enigmatic species, so far only known from the type collection. Favre compared it to A. amarescens, from which it differs consistently by spore shape and ornamentation. Possibly illustrated by Breitenbach and Kränzlin (2000, pl. 128) as A. amarescens. More investigations on this interesting taxon are required. Accepted name: Alnicola fellea (J. Favre) Courtec.
