Type.

Bulliard JBF (1790) Herbier de la France, ou Collection complette des plantes indigenes de ce royaume; Avec leurs Détails Anatomiques, leurs propriétés, et leurs usages en Medecine. Tome 10, plate 436, figure 2, LECTOTYPE of Auricularia phylacteris , here designated (Mycobank Typification No. MBT384912), LECTOTYPE of Thelephora biennis , here designated (MBT384913).

Remarks.

Bulliard (1790) described Auricularia phylacteris and Gmelin (1792) combined it to Thelephora . Seemingly, both Fries and de Candolle (1815) overlooked Gmelin’s combination. Fries (1821) created the name Thelephora biennis , citing under it A. phylacteris and T. phylacteris DC, but seems to attribute it to de Candolle in the index of the Systema Mycologicum 3 ( Fries 1832). This is probably an error and since Fries is the original author of the name, we agree with Petersen (1975) that the authorship is Thelephora biennis Fr.

Fries (1821) indicated “v.ic.”, which would be a reference to the plate in Bulliard (1790). There are no specimens under any of the aforementioned names known to have been examined by Bulliard, de Candolle or Fries. Consequently Bulliard’s plate of A. phylacteris (1790), mentioned by Fries (1821), is here designated as the lectotype of A. phylacteris and T. biennis .

The protologue of T. biennis describes and the plate of A. phylacteris depicts a species which is plicated at the lower part of the basidiome, yellowish-white when young, brown when older and which eventually turns black. It is further described as biennial and growing up from the ground and on to stones and branches, if they are present in its vicinity. It is hence doubtful whether the species in question belongs to the Thelephorales at all and, even though it has been synonymised with P. umbrina by Burt (1916), Litschauer (1933) and Svrček (1958), it does not match any Pseudotomentella described to date.
