Specimen examined. PERU. Cusco: Anta, Chinchaypujio, Parccotica , Chinchipuya , Km 8,650, 3608 m, 13º34′07”S, 72º14′27”W, 17 Apr 2016, leaves of Alnus acuminata, Lado 24408 (MA-Fungi 95746) .

Notes. These specimens highly resemble Ph. mortonii for the pale yellow sporothecae, triple peridia, and diameter of spores (10–12 µm). However, this material differs by the colour of the spores and the capillitium, greyish brown and dense capillitium in the Peruvian specimens and dark brown and lax capillitium in Ph. mortonii .
