Notes. The Peruvian material is similar to the stalked forms of Ph. auriscalpium Cooke , as described in Poulain et al. (2011); however, these specimens present white lime particles instead of yellowish, and spores with a pale band on one side instead of uniform colour. Martin & Alexopoulos (1969) pointed out that the stalked forms of Ph. auriscalpium are unusual and require further study to clarify their true identity.
