根据形态特征和分子证据描述和说明了从北美和中美洲采集的一种新的多孔菌 Daedalea americana 。它的特征是一年生和绒毛状担子果，灰棕色，有棕色到肉桂棕色带，新鲜时呈同心带状绒毛表面，奶油色到粘土粉红色孔表面，圆形到角形孔（每毫米4-5个），椭圆形担子孢子测量为4.0-5.1×2.1-3.0微米。基于内部转录间隔区 (ITS) 区域和核大亚基 (nLSU) 核糖体 RNA 基因区域的系统发育分析支持美洲石斛是属于 Daedalea 的独特物种。
A new polypore, Daedalea americana , collected from North and Central America, is described and illustrated based on morphological characters and molecular evidence. It is characterized by annual and pileate basidiocarps, grayish brown with brown to cinnamon brown band and concentrically zonate pileal surface when fresh, cream to clay-pink pore surface, circular to angular pores (4–5 per mm) and ellipsoid basidiospores measured as 4.0–5.1 × 2.1–3.0 µm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions support D. americana as a distinctive species belonging to Daedalea .
