Two new species of genus Lactarius from India, Lactarius sarthalanus (L. subg. Plinthogalus) and L. drassinus (L. subg. Lactarius) are presented with detailed descriptions, line drawings and microphotographs. The novelty and placement of these taxa within the genus Lactarius are confirmed with ITS based phylogeny.

Two new species of the genus Lactarius from India, Lactarius indoevosmus (L. subg. Lactarius) and L. kanadii (L. subg. Plinthogalus) are presented with detailed descriptions, line drawings, photomicrographs, and comparisons with related species. The novelty and placement of these taxa within the genus Lactarius are confirmed with an ITS-based phylogeny.

Lactarius bhaderwahensis sp. nov. is here described as a new species from coniferous forests of Jammu. Morphological and molecular (nrITS) sequence data placed the new species within Lactarius subg. Plinthogalus. It is characterized by its basidiocarps with brown to cinnamon-brown to greyish brown pileus, abundant white latex that turns light orange to greyish orange, globose to subglobose basidiospores with winged ornamentations having ridges forming a broken reticulum, trichopalisade pileipellis and occurrence under Abies pindrow. A detailed macro-and micro-morphological description along with anatomical photographs, line drawings, phylogenetic analysis and comparisons with similar species are provided.

<em>Amanita indogrisea</em> is described here as a new species from coniferous forests in the Union Territory of Jammu and Kashmir, India based on morpho-anatomy and molecular data. This species is characterized by its small to medium-sized basidiomata, ash grey to lilac-grey pileal surface with ash grey to greyish brown pulverulent-floccose to felted veil remnants, ash grey to greyish-white stipes with ovoid to ellipsoid basal bulb, ellipsoid to elongated basidiospores (10.5–15.0 × 7.0–10.0 μm) and the absence of clamps in all tissues. Molecular phylogenetic analysis based on nuclear ribosomal large subunit (nrLSU) sequences confirmed its identity as a new species nested within <em>A.</em> subgen. <em>Amanitina</em> sect. <em>Roanokenses</em>. Description of the new species is provided in this study.
