Abstract:

A new species of Trichoderma (teleomorph Hypocrea, Ascomycota, Sordariomycetes, Hypocreales, Hypocreaceae), T. amazonicum, endophytic on the living sapwood and leaves of Hevea spp. trees is described. Trichoderma amazonicum is distinguished from closely related species in the Harzianum clade (e.g. Hypocrea alni, H. brunneoviridis, H. epimyces, H. parepimyces, T. aggressivum, T. harzianum, T. pleuroticola and T. pleuroti) by morphological and ecological characteristics and phylogenetic analysis of three loci (ITS nrDNA, tef1 and rpb2). The closest relatives of this species are the facultatively fungicolous species T. pleuroticola and T. pleuroti.
