Abstract

Background: Boletopsis is a genus of the family Bankeraceae with eight accepted species in the world. Species in the genus are ectomycorrhizal fungi and edible. In this study, we conducted a phylogenetic analysis of this genus, based on ITS and nrLSU sequences, using Maximum Likelihood and Bayesian Inference, along with morphological observations in the field and under microscopies. Three species of Boletopsis from China were described and illustrated, including two known species, viz., B.macrocarpa and B.tibetana and one new species, namely B.longipes. A global key to the genus is also provided.

New information: The new species can be distinguished from other species of Boletopsis by its pastel brown pileus when mature, slender stipes measuring 5-13 × 2-3 cm, large basidia, measuring 15-36 × 7-15 μm, solitary or gregarious in mixed forests dominated by trees of the families Pinaceae and Fagaceae at a relatively low altitude about 1000-2600 m. Line drawings of microstructures, colour pictures of fresh basidiomata and detailed descriptions of the new and two known Boletopsis species from China are provided. In addition, a key to the accepted species of the genus worldwide is provided.

标题中国麻麻属（麻麻科，麻麻科）。

背景：Boletopsis是Bankeraceae的一个属，目前在世界上有8个公认的种。本属的种类为外生菌根真菌和可食用真菌。在这项研究中，我们基于ITS和nrLSU序列，利用最大似然和贝叶斯推理，以及野外和显微镜下的形态学观察，对该属进行了系统发育分析。描述并举例说明了3种中国Boletopsis属，包括2种已知种（b.m macrocarpa）和2种西藏属（b.m藏属）和1种新种（b.m ongipes）。还提供了属的全局键。新资料：该新种生长于海拔较低的松科和壳斗科混交林中，成熟时具有淡棕色的菌毛，茎杆细长，长5-13 × 2-3 cm，担子大，长15-36 × 7-15 μm，单生或群居，生长于海拔约1000-2600 m的松科和壳斗科混交林中。本文提供了担子孢子显微结构的线条图、新鲜担子孢子的彩色图片以及中国新种和两种已知担子孢子的详细描述。此外，本文还提供了本属在世界范围内已被认可的种的关键。

期刊介绍： Biodiversity Data Journal (BDJ) is a community peer-reviewed, open-access, comprehensive online platform, designed to accelerate publishing, dissemination and sharing of biodiversity-related data of any kind. All structural elements of the articles – text, morphological descriptions, occurrences, data tables, etc. – will be treated and stored as DATA, in accordance with the Data Publishing Policies and Guidelines of Pensoft Publishers. The journal will publish papers in biodiversity science containing taxonomic, floristic/faunistic, morphological, genomic, phylogenetic, ecological or environmental data on any taxon of any geological age from any part of the world with no lower or upper limit to manuscript size.
