Lepiota sindhudeltana sp. nov. (Agaricaceae; Basidiomycota) from Punjab, Pakistan

Abstract

Lepiota sindhudeltana sp. nov. was found on sandy soil under Saccharum bengalense during fungal surveys to the deltas of the Indus River and the banks of the River Ravi, Punjab, Pakistan. The new species belongs to section Ovisporae, subsection Felininae and is characterized by dull orange appressed squamules on the pileus, thin pileal context, pale yellow lamellae, a stipe rounded to slightly oblong at base, basidiospores broadly ellipsoid to oblong, neither dextrinoid nor amyloid, short, clavate erect pileal hyphae, and narrowly clavate terminal hyphae of the stipitipellis. The closest described species to the new taxon in the phylogenetic tree, based on analysis of ITS and LSU sequences, is L. angusticystidiata. We present the new species with illustrated morphological description, phylogeny, and comparison with related or similar species.

Lepiota brunneogranulosa (Agaricaceae): a new species from Punjab, Pakistan, based on integrated taxonomy

“…Previously, 32 species of Lepiota have been reported from Pakistan (Ahmad et al 1997;Razaq et al 2012;Nawaz et al 2013;Qasim et al 2015;Bashir et al 2020;Niazi et al 2021;Haqnawaz et al 2022). Our current study, based on morphological and molecular data of the species collected from Punjab, Pakistan, indicated that this is a genuine member of the genus Lepiota and also a new taxon to science.…”
