Abstract: Macrofungi belonging to the genus Porodaedalea were collected during a fungal biodi- versity study in Murree, Pakistan. Morphological characteristics and molecular phylogenetic analy- ses were used to identify the basidiomata to species. Macro- and microscopic characterization and ITS1-5.8S-ITS2 nrDNA sequence-based phylogenetic analysis showed the taxonomic position as Porodaedalea indica. The genus Porodaedalea indica, is described here as a new record from Pa- kistan. Key words: Hymenochaetaceae; pathogenic fungus; taxonomy

Introduction

The genus Porodaedalea Murrill (Hymenochaetaceae, Hymenochaetales, Basidiomy- cota) belongs to one of the most taxonomically difficult groups of hymenochaetoid pore fungi distributed in the Northern hemisphere. Mainly species of Porodaedalea (Phelli- nus) pini (Brot.) Murrill and P. chrysoloma (Fr.) Fiasson & Niemelä are reported as widely distributed (Núnez & Ryvarden 2000, Niemelä et al. 2005, Tomšovský et al. 2010, Ryvarden & Melo 2014). A basic outline for Porodaedalea was established by Fiasson & Niemelä (1984) based on morphological and biochemical features. Wagner & Fischer (2002) confirmed Porodaedalea as an independent genus through the nuclear large sub unit (nLSU) ribosomal RNA-based phylogeny. The basidiomata are perennial, effused-reflexed to pileate, solitary to imbricate, and corky to woody hard. The colour is rust brown to dark grey on the upper surface, while the poroid surface is ochre brown or rust brown to umbre brown, and more or less shining. The pores are circular to angular, tending to split and becoming irregular to daedaleoid and labyrinthine. Setae are commonly present in the hymenium. In some areas the species
