The taxonomy of Pholiota fusus - a critical evaluation.

Pholiota fusus (Batsch) Singer based on Agaricus fusxis Batsch is included in most floras of the 19th century and appears in some works of the 20th century. Recent records documented by herbarium material were published by Bon, Tjallingii-Beukers and Noordeloos. A careful revision of these collections showed that they most probably represent an aberrant robust for m of Hypholoma sublateritium. The original Agaricus fusus Batsch is hard to interpret. The species probably does not belong to Pholiota or not even to brown-spored fungi. Later interpretations of Pholiota fusus are dubious and cannot be verified due to the lack of any herbarium material. The concept of Pholiota fusus used by some authors of the 20th century follows that of Ricken. However, Flammula fusa sensu Ricken is probably a non-existing entity based on a mixture of characters taken from various spccies. There is no reliable evidence that a separate species of Pholiota corresponding to Batsch’s original description or various later interpretations really exists. Consequently, the name Pholiota fusus must be considered a nomen dubium and should be rejected.
