Morphological characters and multigene phylogenetic analyses, which encompass ITS, LSU, <em>rpb2</em>, and <em>tef1</em> sequences, distinguish this species. <em>Cystolepiota flavolamellata</em> exhibits the following unique set of characteristics: basidiomata covered with light brown to brown granules or large pyramidal squamules; free yellowish white to light yellow lamellae; broadly ellipsoid to oblong-amygdaliform to ovoid basidiospores; absence of pleurocystidia; variably shaped cheilocystidia, <em>i.e.,</em> oblong, clavate with or without appendicular apex, conical to utriform, fusiform; an epithelium for the pileus and stipe covering; and presence of clamp connections. Molecular analyses based on multiple genes confirm its separation from other known and sequenced <em>Cystolepiota</em> species.</span></span></span></p>2024-04-18T00:00:00+12:00Copyright (c) 2024 Phytotaxahttps://phytotaxa.mapress.com/pt/article/view/phytotaxa.645.1.3<strong>Taxonomic revision of <em>Schizotechium</em> (Caryophyllaceae) in Nepal, including one new record</strong>2024-02-12T06:55:59+13:00RASHIKA KAFLErashikakafle@gmail.comGAURAV PARMARgaurav_mascot4u@yahoo.com<p align="justify"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">Taxonomic revision of <em>Schizotechium</em> (Caryophyllaceae) in Nepal was done based on the extensive study of herbarium specimens deposited in various herbaria as well as our own collections. According to this study, Nepal is home to four species of <em>Schizotechium</em>: <em>S. delavayi,</em> <em>S. devendrae</em>,<em> S. monospermum</em> and <em>S. paniculatum. Schizotechium devendrae </em>that was collected from several locations in Nepal is reported to be a new record for Nepal<em>. Schizotechium delavayi </em>and <em>Stellaria monosperma</em> f. <em>scabrifolia</em> have been found to be conspecific, but due to prior publication of <em>S. delavayi</em>,<em> S. monosperma</em> f. <em>scabrifolia</em> has been treated as a synonym of <em>S. delavayi.</em> Lectotypification has been done for <em>Stellaria crispata</em>,<em> Stellaria glandulifera </em>and<em> Stellaria nyalamensis. </em>Previous studies have ignored to mention a <em>Schizotechium</em> species as the type of the genus <em>Schizotechium</em>. Therefore, this study considered <em>Schizotechium monospermum </em>as the type species of the genus <em>Schizotechium</em> in order to validly publish the genus in compliance with the rules of ICN. Taxonomic treatment, habitat, distribution, photo plates, as well as keys to each species, have been provided. </span></span></span></p>2024-04-18T00:00:00+12:00Copyright (c) 2024 Phytotaxahttps://phytotaxa.mapress.com/pt/article/view/phytotaxa.645.1.4<strong>Novelties in <em>Randia</em> L.

The muricate fruits is an uncommon feature among species in this genus. <em>R. sulbahiana</em> is characterized by the facultative presence of thorns, linear or filiform calyx lobes, and the acute apex of corolla lobes. We provide descriptions, illustrations, figures, an assessment of conservation status, and distribution map of both species.
