Treatment

146. º Physarum rubiginosum Fr. & Palmquist, Symb. View in CoL gasteromyc., fasc. 3: 21 (1818)

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 24423 (MA-Fungi 95762) GoogleMaps .

Notes. Physarum rubiginosum has orange scales in the peridium and capillitium ( Fig. 4C View FIGURE 4 ) with angular, calcareous concretions. Similar to Ph. lateritium (Berk. & Ravenel) Morgan , differing by its capillitium with calcareous concretions with rounded borders.

Known from Europe and North America ( Poulain et al. 2011), in the Neotropics, it has been recorded from the Windward Islands, Jamaica, and Mexico ( Lado & Wrigley de Basanta 2008). It is the first record for South America, inhabiting the litter of Alnus acuminata trees.
