Tulostoma ahmadii, a new species found in the subtropical pine forest of Malakand, Pakistan, is described and illustrated. It is characterized by parallel to squamulose deep reddish brown scales on stipe with bulbous base, warty exoperidium, and tubular and relatively large-sized basidiospores. | Turkish Journal of Botany Turk J Bot (2016) 40: 218-225 © TÜBİTAK doi: Research Article Tulostoma ahmadii sp. nov. and T. squamosum from Pakistan 1 2, 3 2 Shah HUSSAIN , Nousheen YOUSAF *, Najam-ul-Sehar AFSHAN , Abdul Rehman NIAZI , 4 2 Habib AHMAD , Abdul Nasir KHALID 1 Department of Botany, Hazara University, Mansehra, Pakistan 2 Department of Botany, University of the Punjab, Quaid-e-Azam Campus, Lahore, Pakistan 3 Center for Undergraduate Studies, University of the Punjab, Quaid-e-Azam Campus, Lahore, Pakistan 4 Department of Genetics, Hazara University, Mansehra, Pakistan Received: Accepted/Published Online: Final Version: Abstract: Tulostoma ahmadii, a new species found in the subtropical pine forest of Malakand, Pakistan, is described and illustrated. It is characterized by parallel to squamulose deep reddish brown scales on stipe with bulbous base, warty exoperidium, and tubular and relatively large-sized basidiospores. Macro- and microscopic features along with sequence data demonstrated that Tulostoma ahmadii is a distinct species from other members of Tulostoma. T. squamosum, which is represented here as a new record for the country, has also been characterized on a molecular basis. Key words: ITS, Malakand, new species, stalked puffballs, Tulostoma 1. Introduction The genus Tulostoma Pers. is a large group of gasteroid fungi, commonly called stalked puffballs, belong to the family Agaricaceae (Agaricales: Basidiomycota). This genus is characterized by a rounded spore case with apical mouth attached to a stipe. It is represented by 81 established species (Kirk et al., 2008; Caffot et al., 2011) but more than 100 names for this group have been cited in the literature (Wright, 1987; Moreno et al., 1992, 1995, 2002; Fan and Liu, 2005). The distribution of these fungi is worldwide, but they prefer xeric, warm, and sandy habitats (Wright, 1987; Esqueda-Valle
