Fistulinella ruschii, sp. nov., and a new record of Fistulinella campinaranae var. scrobiculata for the Atlantic Forest, Brazil

ABSTRACT

Fistulinella is a small genus of boletoid fungi in the subfamily Austroboletoideae in the order Boletales. In this paper, F. ruschii from the Atlantic Forest is proposed as new to science and F. campinaranae var. scrobiculata, known from the Brazilian Amazon forest, is recorded for the first time in the Atlantic Forest. Macro- and microscopic descriptions, molecular data (nuc rDNA ITS1-5.8S-ITS2 and nuc 28S rDNA), photographs of the basidiomata, and scanning electron microscopy images of basidiospores are provided for both species. Based on sampling of six taxa, New World Fistulinella is found to be a strongly supported monophyletic group, but the genus at large is nonmonophyletic.
