Lepiota lahorensis sp. nov. is described from Lahore, Pakistan. Its characterizing features are pinkish brown pileus with dark brown furfuraceous scales, oblong to ellipsoid spores, clavate cheilocystidia, and pileus covering made up of trichodermal elements without shorter elements at their base. | Turkish Journal of Botany Turk J Bot (2016) 40: 419-426 © TÜBİTAK doi: Research Article A new species of Lepiota, Lepiota lahorensis, from Lahore, Pakistan 1, 1 2 Tayyaba QASIM *, Abdul Nasir KHALID , Else C.

Its characterizing features are pinkish brown pileus with dark brown furfuraceous scales, oblong to ellipsoid spores, clavate cheilocystidia, and pileus covering made up of trichodermal elements without shorter elements at their base. The phylogenetic analysis based on nuclear ribosomal internal transcribed spacer sequence shows its unique position in sect. Ovisporae.

Introduction The family Agaricaceae is a saprotrophic group of fungi exhibiting wide diversity in macro and microscopic features. With the advent of DNA ribotyping, some secotioid genera have also been included in this family, ., Endoptychum agaricoides Czern., Podaxis pistillaris (L.) Fr., and Longula texensis (Berk. & . Curtis) Zeller. Morphologically the family was divided earlier in four tribes (Singer, 1986; Wasser, 2002), but later tribe Cystodermae was excluded, which has also been confirmed by molecular studies (Johnson and Vilgalys, 1998; Moncalvo et al., 2002). The other three tribes are Agariceae, Lepioteae, and Leucocoprinae (Singer, 1986; Vellinga, 2004). Lepioteae comprises species with nonmetachromatic white spores and regular lamella trama, while Leucocoprinae is represented by taxa having trabecular lamellar trama and metachromatic spores, without or with a germ pore. Bon (1993) combined these two tribes
