Since Psilocistella quercina was described in 1977, it is considered a doubtful taxon, and therefore not currently accepted. A bibliographic revision, together with recent studies on collections from France and the Canary Islands (Spain) are used to provide evidence about its relevance. A provisional key to the genus is also given

A focus is made upon two species among the Hyaloscyphaceae collected during the 2010 Ascomycetes foray in Saint-Jean-la-Vêtre (France, Loire), Calycina conorum (Rehm) Baral and Cistella albidolutea (Feltgen) Baral. A short description along with macro and micro pictures are proposed for these rarely documented species in the available common literature
