食用菌是大型真菌的重要类群，具有重要的食用和药用价值。食用菌产业承载着保障食物安全、促进农民增收和国民健康的国家重任。我国食用菌资源丰富，已发现900多种，而河北省的食用菌资源目前鲜有调查，大部分地区未见报道。侧耳属（Pleurotus）和木层孔菌属（Phellinus）真菌类群是河北省重要的食用真菌和药用真菌，以往河北省的学者对这两个属真菌的研究和报道仅限于形态鉴定方面，可能存在鉴定不准确等问题，需要结合分子系统学手段进一步进行深入的调查和研究予以验证。本项目拟对河北省野生食药用真菌资源进行广泛的资源调查、标本采集和菌种分离保藏，明确河北省食药用真菌种类的多样性及其寄主和地理分布；并对侧耳属和木层孔菌属进行系统发育研究，搞清河北省侧耳属和木层孔菌属属内种间的亲缘关系。研究结果将为河北省野生食药用真菌的驯化、筛选优良栽培品种和种质资源的保护利用奠定基础。

Edible mushrooms are very important groups of fungi with momentous edible and medicinal value. The industry of Edible mushrooms takes heavy responsibility to guarantee food security, promote the farmers' income and national health. Edible mushrooms are abundant in our country, more than 900 species have been discovered; however, edible mushrooms in Hebei province are currently reported only in a small part of areas, most areas have not been investigated. Species of Pleurotus and Phellinus are important edible and medicinal mushrooms in Hebei province. In the past, the research of these two genera in Hebei province were merely based on morphological characters, and there may be some problems such as inaccurate identification, which needs to be deeply investigated and studied by molecular phylogeny. The project intends to carry out extensive resource investigation, specimen collection and isolation of wild edible and medicinal mushrooms in Hebei province to make the diversity, their hosts and geographical distributions clear, and to study the phylogeny of Pleurotus and Phellinus to figure out the phylogenetic relationship of species in each genus in Hebei province. The findings will lay the foundation for domesticating and screening the excellent cultivars，and protecting the germplasm resources of wild edible and medicinal mushrooms in Hebei province.
