32. º Craterium rubronodum G. Lister, Trans. Brit. Mycol. Soc. 5: 74 (1915)

Specimen examined. PERU. Ancash: Huari, Huari, Challhuyacu , Huamantanga , 7 km south of Huamparán , 3238 m, 9º18′13”S, 77º10′16”W, 12 May 2018, woody debris, Lado 26463a (MA-Fungi 97247) .

Notes. It differs from other species by the cup or saucer-shaped sporotheca ( Fig. 3B ) and spores ornamented with unevenly distributed spinules, sometimes joining to form a broken reticulum. Martin & Alexopoulos (1969) described the capillitium with pale pink calcareous nodules, but in the Peruvian specimens, they were yellowish in transmitted light.

So far, it is known from the Democratic Republic of the Congo, Mexico, Asia and Malta ( Poulain et al. 2011, GBIF 2022). It represents the first record for South America, found inhabiting the woody remains of vegetation associated with crops, in the department of Ancash.
