Termitomyces acriumbonatus sp. nov. (Lyophyllaceae, Agaricales) from Pakistan

Four Termitomyces samples were collected in fungal surveys during 2016–2017 at Pabbi Forest Park, Punjab, Pakistan. Detailed morphological examination showed the four collections represent a new species. The phylogenetic analyses of Internal Transcribed Spacer (ITS) and Larger Sub-Unit (LSU) genes also supported the morphology to establish the new species which we describe and illustrate in this paper. The new species, Termitomyces acriumbonatus, is characterized by a small pileus 15–30 mm diam., with pointed grayish brown perforatium, cylindrical smooth stipe, and ellipsoid, 6.1−8.7 × 4.5–6.5 μm sized basidiospores.
