The Myxomycetes are a group of amoeboid protists involved on the decomposition of organic matter of plant origin. In Peru, around 22% of the species known worldwide have been recorded, but the territory is studied unevenly, and the Amazon tropical forests, and particularly the central jungle, has barely been explored. In the present work, the result of expeditions carried out in 2020 to the jungle of Pasco, Oxapampa province, is provided. Six species unknown in this territory are reported, and the species Craterium roseum is recorded for the first time to Peru. The species richness and diversity of this territory is underestimated and need of more exhaustive studies to have a precise idea about its myxobiota.

Estudios recientes de mixomicetos han revelado una alta diversidad de especies en ambientes tropicales; sin embargo, aún existen grandes vacíos de información en el Neotrópico. En el presente trabajo, informamos por primera vez la presencia de las especies Lamproderma gulielmae y Trichia ambigua en los Andes tropicales peruanos. Los datos presentados amplían la distribución geográfica de estas dos especies al hemisferio sur y resaltan el papel de los bosques altoandinos como refugio para los mixomicetos.
