| 8:15a | [Fungi • 2022] Lepiota sindhudeltana (Basidiomycota: Agaricaceae) • A New Species 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. Keywords: Indus Valley, Felininae, biodiversity, Muzaffargarh, pileal elements, Fungi
Lepiota sindhudeltana Haqnawaz, Niazi, Usman & Khalid sp. nov. Etymology:— ‘sindhudeltana’ (Latin) refers to the locality of the taxon i.e., the delta of the River Sindh (Indus River).

| 10:23a | [Fungi • 2016] Laccaria rubroalba (Agaricales: Hydnangiaceae) • A New Species from Southwestern China
Abstract The novel species Laccaria rubroalba is described from Southwestern China by using both morphological characteristics and molecular data. It is characterized by small basidiomata; reddish white pileus when moist or young, white to pale when dry; 4-spored basidia and globose to broadly ellipsoid, hyaline, moderately echinulate basidiospores. Phylogenetic relationships inferred from ITS sequence data confirmed the separation of this new species from other closely related species in the genus Laccaria. The new species is compared with similar taxa. A description, line drawings and colour photographs of the new species, and phylogenetic tree to show the placement of the new species are provided.
