ABSTRACT
Morphological revision and phylogenetic analysis based on nITS and nLSU of specimens previously considered to be a species related to Fulvifomes robiniae from South America revealed a new species of Fulvifomes, i.e. Fulvifomes wrightii. It grows on Libidibia paraguariensis, a Fabaceae distributed in the Chaco Region. The new species is characterised by a perennial, ungulate basidioma with a rimose pileal surface, 6-7 pores per mm, a homogenous context, indistinct stratified tubes and abundant crystals in tube trama and hymenia. Illustrations, taxonomic analyses and a key to the Fulvifomes species recorded from the Americas is provided. Citation: Martínez M, Salvador-Montoya CA, de Errasti A, Popoff OF, Rajchenberg M (2023).

ABSTRACT
This study investigated the incidence and diversity of Tolypocladium within trunks of south Florida slash pines (Pinus densa). Thirty-five isolates were recovered from trunk tissue including living phloem, cambium, and sapwood. Two novel species of Tolypocladium (T. subtropicale and T. trecense) are described here based on morphological and molecular analysis of concatenated LSU, ITS, tef-1, tub, and RPB1 sequences. Our findings expand our understanding of the distribution, diversity, and ecology of this genus and confirm that it is widely spread as an endophyte across ecosystems and hosts. Strains collected in this survey will be used in future bioassays to determine their potential ecological roles as mycoparasites or entomopathogens.
