Two new species, Fomitopsis mounceae and F. schrenkii (Polyporales, Basidiomycota) in the F. pinicola species complex in North America, are described and illustrated. Previous molecular phylogenetic analyses identified three well-delimited lineages that represent F. mounceae and F. ochracea from Canada, the Appalachian Mountains, and the northern United States and F. schrenkii from western and southwestern regions of the United States. Fomitopsis pinicola sensu stricto is restricted to Eurasia and does not occur in North America. Morphological descriptions of basidiocarps and cultures for F. mounceae, F. schrenkii, and F. ochracea are presented. The three species are readily differentiated by nuc rDNA internal transcribed spacer (ITS1-5.8S-ITS2 = ITS) sequence, geographic distribution, and basidiospore size. Polyporus ponderosus H. Schrenk is an earlier illegitimate synonym of F. schrenkii. Both F. mounceae and F. schrenkii have a heterothallic multiallelic incompatibility system.
描述并说明了北美松生拟层孔菌物种复合体中的两个新物种，即芒氏拟层孔菌（Fomitopsis mounceae）和施氏拟层孔菌（F. schrenkii）（多孔菌目，担子菌门）。先前的分子系统发育分析确定了三个界限分明的谱系，分别代表来自加拿大、阿巴拉契亚山脉和美国北部的芒氏拟层孔菌和赭黄拟层孔菌（F. ochracea），以及来自美国西部和西南部的施氏拟层孔菌。狭义的松生拟层孔菌仅限于欧亚大陆，在北美不存在。给出了芒氏拟层孔菌、施氏拟层孔菌和赭黄拟层孔菌的担子果和培养物的形态描述。这三个物种可通过核糖体DNA内转录间隔区（ITS1-5.8S-ITS2 = ITS）序列、地理分布和担孢子大小轻松区分。 ponderosus H. Schrenk是施氏拟层孔菌的一个较早的非法同义词。芒氏拟层孔菌和施氏拟层孔菌都具有异宗配合的多等位基因不相容系统。
