In this study, three new wood-inhabiting fungal species, </span><span lang="en-GB"><em>H. marginatum</em></span><span lang="en-GB">, </span><span lang="en-GB"><em>H. tropicum</em></span><span lang="en-GB"> and </span><span lang="en-GB"><em>H. yunnanense </em></span><span lang="en-GB">are proposed based on a combination of the morphological and molecular evidence. </span><span lang="en-GB"><em>Hyphoderma marginatum </em></span><span lang="en-GB">is characterized by the cracking, hard fragile basidiomata having smooth hymenial surface with the upwarping margin, a monomitic hyphal system with clamped generative hyphae, and cylindrical basidiospores. </span><span lang="en-GB"><em>Hyphoderma tropicum </em></span><span lang="en-GB">is characterized by the resupinate basidiomata with tuberculate hymenial surface, presence of the moniliform cystidia, and ellipsoid to cylindrical basidiospores (</span><span lang="en-GB">6.5</span><span lang="en-GB">–7.5 × 3–4 µm), </span><span lang="en-GB"><em>Hyphoderma yunnanense </em></span><span lang="en-GB">is characterized by the corneus basidiomata, presence of clamped septate cystidia, and ellipsoid to cylindrical basidiospores. Sequences of ITS and nLSU rRNA genes were used for phylogenetic analyses using maximum likelihood, maximum parsimony, and Bayesian inference methods.

Here, we present an annotated checklist of flora of the sanctuary, which includes 397 taxa (392 species, 1 subspecies, 3 varieties and 1 forma) belonging to 254 genera in 76 families. Asteraceae was the dominant family with 57 species, followed by Rosaceae and Lamiaceae with 28 and 27 species respectively. Likewise, </span><span lang="en-GB"><em>Salix</em></span><span lang="en-GB"> and </span><span lang="en-GB"><em>Veronica</em></span><span lang="en-GB"> were the dominant genera with 7 species each, followed by </span><span lang="en-GB"><em>Artemisia</em></span><span lang="en-GB"> with 6 species. The herbs were dominant (307 species, 77.33%) followed by trees (41, 10.33%). Lifespan wise, perennials were dominant (318 species, 80.1%), followed by annuals (66, 16.62%). The hemicryptophytes were the dominant life forms (224 species, 56.42%), followed by phanerophytes (80, 20.15%). Further, nine species occurring in sanctuary are currently recognized under different IUCN threat categories. The checklist provides the first-ever comprehensive documentation of the flora from this Kashmir Himalayan protected area, supplemented with details on natural life-history traits and up-to-date conservation status. Hopefully, the study will be immensely useful in guiding suitable conservation strategies and management planning of protected areas in the region.</span></span></span></span></p> TAJAMUL ISLAM ANZAR AHMAD KHUROO IRSHAD A.
