Abstract

The family Boletaceae primarily represents ectomycorrhizal fungi, which play an essential ecological role in forest ecosystems. Although the Boletaceae family has been subject to a relatively global and comprehensive history of work, novel species and genera are continually described. During this investigation in northern China, many specimens of boletoid fungi were collected. Based on the study of their morphology and phylogeny, four new species, Butyriboletus pseudoroseoflavus, Butyriboletus subregius, Tengioboletus subglutinosus, and Suillellus lacrymibasidiatus, are introduced. Morphological evidence and phylogenetic analyses of the single or combined dataset (ITS or 28S, rpb1, rpb2, and tef1) confirmed these to be four new species. The evidence and analyses indicated the new species’ relationships with other species within their genera. Detailed descriptions, color photographs, and line drawings are provided. The species of Butyriboletus in China were compared in detail and the worldwide keys of Tengioboletus and Suillellus were given.

Highlights

Boletaceae Chevall. [1], a family with more than 70 genera, is one of the most prominent and diverse among the basidiomycetes [2]
The alignment was submitted to TreeBASE
The phylogenetic tree showed that two T. subglutinosus sequences formed an independent lineage, with bootstrap proportions (BP) = 100 and posterior probability (PP) = 1, and formed a sister group with

Summary

Introduction

Boletaceae Chevall. [1], a family with more than 70 genera, is one of the most prominent and diverse among the basidiomycetes [2]. [1], a family with more than 70 genera, is one of the most prominent and diverse among the basidiomycetes [2]. It is mainly characterized by being tubulose with infrequent lamellate or loculate hymenophora, and by a fleshy context. The family Boletaceae was established nearly two centuries ago, the species diversity of the family increased significantly in the last few decades [7,8,9,10,11,12,13,14,15,16,17,18,19]. In the past two decades, new genera and new species have rapidly increased, and the evolution of ectomycorrhizas of Boletales was gradually disclosed [23,24]
