Tillandsia tequilana, a new species from the state of Jalisco, Mexico, is described and illustrated. The proposed species is compared to T. aguascalientensis, T. moronesensis, and T. schusteri, taxa with some morphological similarities. Tillandsia tequilana differs from these species in the shape and size of the leaf sheath, spikes and floral bracts, in the shape of the sepals, and also in the flowering time. Images and a distribution map of the new species are included.

Thymus dreatensis (Lamiaceae), a rare species, was considered to be strictly endemic to Algeria, until it was recently discovered on the eastern Kroumirian mountains of Tunisia. The species is one of the very rare and few taxa of Thymus sect. Serpyllum subsect. Insulares and is characterized mainly by its small habit with reptant stems, broadly ovate to elliptical, entire leaf blade, and a capitate to oblong inflorescence with entire bracts, which are different from the leaves. The name is here lectotypified with a specimen housed in the Montpellier University Herbarium. The population is here reported for the first time as a new floristic record for Tunisia. Moreover, geographical distribution and habitat of T. dreatensis is given. In addition, the nomenclature of three species of Thymus that are morphologically close to T. dreatensis and endemic to North Africa, is discussed: T. atlanticus is lectotypified with a specimen housed in Herb. K; T. guyonii is neotypified with a specimen housed in Herb. P; T. pallescens is lectotypified with the same detailed plate on which the name was published.
百里香（Lamiaceae）是一种稀有物种，曾被认为是阿尔及利亚的特有种，直到最近才在突尼斯东部的克鲁米里安山脉被发现。该物种是百里香科（Thymus sect.Serpyllum subsect.其主要特征是体型小，茎呈爬行状，叶片宽卵形至椭圆形，全缘，花序头状至长圆形，苞片全缘，与叶片不同。蒙彼利埃大学标本馆收藏了一份标本，在此对该名称进行了标本分型。该种群首次作为突尼斯的新花卉记录被报道。此外，还给出了 T. dreatensis 的地理分布和栖息地。此外，还讨论了形态上与 T. dreatensis 相似且为北非特有的三种百里香的命名方法：大西洋百里香（T. atlanticus）通过保存在 Herb.K；T. guyonii 通过保存在 Herb.P；T. pallescens 的原型标本与名称公布时的标本相同。

A new species of coralloid fungus from Meghalaya, India, Ramaria pseudovinosimaculans, belonging to the genus Ramaria subg. Laeticolora, is proposed based on taxonomy and phylogenetic studies of the internal transcribed spacer of the ribosomal DNA (nrITS) region. The morphological characteristics, together with molecular studies, confirmed that the species is a novel species. The species is characterized by a small to medium-sized, radially branched, white to yellowish white basidiomata with a base colour of light brown to violet red and greyish yellow elsewhere that turns brownish orange when bruised, a cylindrical to bacilliform basidiospore, basally clamped four-spored basidia, and clamped hyphae. An inclusive description, illustration, and comparison with morphologically similar and related species are provided.

A novel species, Fusarium kamalianum, belonging to the Fusarium oxysporum species complex (FOSC), is established to accommodate a fungal pathogen that was isolated from infected Chamaedorea seifrizii (Bamboo palm). The identification of this pathogenic strain was determined based on the cultural features, asexual-morphs, and phylogenetic analysis based on translation elongation factor 1-alpha (tef-1α), RNA polymerase second largest subunit (rpb2), internal transcribed spacer region (ITS), 28S large subunit (LSU), and β-tubulin (tub2) sequence data. The detailed taxonomic descriptions, cultural, microscopic images, and phylogenetic trees are presented for the introduced taxon. The sequencing data of this isolate exhibited substantial distinctness from the previously discovered species of Fusarium and created a unique distinct clade. This is the first study that reports infection in Chamaedorea seifrizii plants caused by Fusarium species.

Punjuba is a Neotropical genus of the mimosoid clade (Leguminosae). The genus was recently restablished and is recognized by presenting shrubs and trees, with lax racemes or spiciform racemes, leaves with 1–3 pairs of pinnae and 2–7 pairs of leaflets in each pinna, thin and lateraly compressed legumes, curved to spiral, and seeds lacking pleurogram. Recent advances on legumes systematics have been producing great challenges on the circumscription of genera, especially on the mimosoid clade. Molecular phylogenetic studies confirm that Punjuba is monophyletic, and a revision of the genus and species circumscriptions are needed. Here we present a taxonomic revision of Punjuba, providing an identification key for all species currently recognized in the genus, morphological descriptions, and distribution maps. We recognize six species in the genus: P. callejasii, P. centiflora, P. killipii, P. lehmannii, P. racemiflora and P. foreroana, being the last one described here as a new species. Abarema josephi is proposed as a new synonym of P. lehmannii. Morphological characters including the inflorescence, indumentum, leaves and leaflets, besides quantitative characters, were applied as diagnostic to recognize the species.

Within the genus Mallocybe, new species have been continuously discovered on a global scale, yet only few species have been reported from China. During surveys of macro-fungi diversity and taxonomy in Sichuan Province, China, two samples were collected in the forests dominated by Quercus glauca and identified as a new member of this genus, namely Mallocybe longquanensis. Morphologically, M. longquanensis is distinguished by its small-sized basidioma, light brown to yellowish-brown pileus covered with tomentose-fibrillose, ellipsoidal or ovoid basidiospores, as well as the utriform, clavate to cylindrical cheilocystidia. Multi-gene phylogenetic analysis of ITS, LSU, and rpb2 also revealed that the new taxon forms a distinct lineage within the genus Mallocybe. The detailed morphological features, color photographs, and comparisons with morphological similar taxa are provided.

A new dioecious species of Tolypella, T. mongolica sp. nov. from the section Tolypella, was described using an integrative taxonomy. It was found in three distant localities – shallows of a brackish small lake and a channel in the midland steppe in Mongolia and the Altai Mountains, and a small brackish water body in the dry steppe in Southeast Europe. It differs from other species in rbcL and ITS sequences and in distinct complex ornamentation of the oospore surface, varying from sparsely coarsely tuberculate to having the appearance of an aerial view of mountain landscape with acute to mostly sharp edges of elements at probably the ripest stage. Wide intrapopulation variability of expression of this trait, only partly explainable by oospore ripening stage, was found and illustrated for two populations, indicating previous underestimation of this phenomenon in taxonomic research. T. mongolica is richly fertile and appears to be ephemeral as most species of this genus. Only female plants were found in all localities. The absence of male plants could be referred to either their earlier development during the growing season or, less likely, parthenogenesis in this species. The description of the new species suggests taxonomic changes for two dioecious species of charophytes. Tolypella porteri stat. et comb. nov. was validated here. T. jwalae was recognized as a species of Nitella, N. jwalae comb. nov.

Rhaponticoides nuriae is described as a species new to science. Its affinities within the genus are analyzed and discussed. The new species is obviously very different from the two described species in Morocco and can be easily distinguished from those species by its distinct appendage with a very wide scarious margin and by its longer achenes. According to analyses of sequenced nuclear markers ITS and ETS, the new species cannot be reduced to any of the existing Rhaponticoides species. This may suggest that the species is an early branch separated from the bulk of the genus. The conservation issue is considered since the plants occur in a very cultivated zone. Photographic illustrations of the new plant species and an updated key to the Rhaponticoides species in Morocco are also provided.

During field surveys in the Atlantic Forest of Southern Brazil, specimens of a poroid and pileate species of Hymenochaetaceae were found and are described as a new species, Neomensularia meridionalis. This species is morphologically and phylogenetically (ITS and nLSU) close to Neomensularia crocitincta, distributed in Central America, Cuba and Jamaica, but can be distinguished by its larger basidiomata, a duplex context featuring a distinct black line, and golden yellow basidiospores. Additionally, an updated identification key for Neomensularia species worldwide is provided.
