New records of Myxomycetes from Peru

Abstract

We report 19 species of Myxomycetes for first time in Peru. Macbrideola spinispora L.M. Walker, G. Moreno & S.L. Stephenson, previously known only from the type collection from Costa Rica, is now reported for South America, enlarging its distribution considerably. The Myxomycetes were collected in Wayqecha Biological Station, a conservation area in the Cuzco region. The specimens were deposited in the South Peruvian Herbarium (HSP) and the Real Jardín Botánico de Madrid (MA-Fungi). The number of Myxomycetes currently recorded from Peru is increased to 174 species.

Myxomycetes of the Atlantic Rainforest: species on the ground litter from Pedra Talhada Biological Reserve (Alagoas, Brazil)

“…Among the species identified in the present study, A. cinerea, P. cinereum, P. viride and S. fusca are common in ground litter and other microhabitats (Bezerra et al 2014). Some of the species obtained in this study are typically found in the ground litter, such as C. leucocephalum and L. scintillans, which have records as foliicolous in Atlantic Rainforest and Cerrado (Cavalcanti et al 2015), as well as recently described species such as P. longipes and M. spinosispora, which are only registered in ground and aerial litter (Walker et al 2014;Treviño-Zevallos & Lado 2020). The type material of D. verrucisporum was collected on dead leaves in the Panama Canal Zone, as well as in other countries such as Mexico (López & García 1996), confirming the species preference for ground litter.…”

ADICIONES A LA MIXOBIOTA DE LA SELVA CENTRAL DE PERÚ: NUEVOS REGISTROS Y PRIMERA CITA DE Craterium roseum (PHYSARALES, MYXOMYCETES, AMOEBOZOA)

“…El primer registro de un Myxomycete en Perú data de 1829 (Rudolphi, 1829), pero hay que esperar hasta el siglo XXI para disponer de los primeros listados provisionales de las especies que habitan en el paıś Rojas et al, 2011). En los últimos 10 años, sin embargo, el paıś ha suscitado el intereś de los investigadores y, entre los años 2012 y 2018, el proyecto Myxotropic (www.myxotropic.org), ha realizado estudios de extensos territorios y múltiples ecosistemas (Lado et al, 2016(Lado et al, , 2019Treviño-Zevallos & Lado, 2020b;Treviño-Zevallos, 2021;Treviño-Zevallos et al, 2023), lo que ha permitido descubrir nuevas especies (Wrigley de Basanta et al, 2015Basanta et al, , 2018 y poseer un conocimiento mayor y más preciso sobre la mixobiota peruana. En la actualidad, Perú cuenta con 230 especies de Myxomycetes catalogadas, lo que le sitúa entre los paıśes con más diversidad y riqueza de especies de Sudamérica y el Neotrópico (Treviño-Zevallos et al, 2023).…”
