Scytinopogon caulocystidiatus and S. foetidus spp. nov., and five other species recorded from Brazil

Abstract

Seven species of Scytinopogon in the Atlantic Forest of Brazil are described. Scytinopogon caulocystidiatus and S. foetidus are proposed as new species based on morphological and molecular data. Five other species are presented: S. chartaceus, S. dealbatus and S. robustus, originally described from Brazil; and S. pallescens and S. scaber, previously reported for Brazil. Illustrations of the basidiomata and microstructures, including SEM images of ornamented basidiospores, are provided for all taxa. Comparisons with morphologically similar taxa and a key to the seven species of Scytinopogon known to occur in Brazil are also presented.

A new species, new combination, and a nomen novum in the genus Trechispora from India

“…Remarks: Species description of the present collection matches with that of Scytinopogon dealbatus (now T. dealbata) described by Corner (1970) and Furtado et al (2021). S. scaber resembles the present specimen by its whitish basidiomata, but differs by its papillate branches.…”

“…Remarks: The present specimen ts with the species description of S. echinosporus by Corner (1950) and Furtado et al (2021). Although the species should have been considered as belonging to Trechispora according to the synonimization of Scytinopogon with Trechispora based on Liu et al (2022) and Furtado et al (2021), due to the lack of molecular evidence, a formal genus transfer had not yet been done.…”

“…It was reported that many clavarioid basidiomata in Trechispora are white (Furtado et al 2021). Here three species were reported as so.…”

Outline, Divergence Times, and Phylogenetic Analyses of Trechisporales (Agaricomycetes, Basidiomycota)

“…Above all, ampullate septa are only known from Scytinopogon , Trechispora , and Porpomyces mucidus (Pers.) Jülich within Trechisporales ( Furtado et al, 2021 ; Meiras-Ottoni et al, 2021 ).…”
