A cup fungus producing ascomata on senescing to dead rhizomes of bamboo in East China is described as Pseudoplectania mystica sp. nov. (Ascomycota, Pezizales) based on morphological, ecological and phylogenetic evidence. Some sequences of unidentified endophytic fungi uploaded to the GenBank database by other researchers were also identified as P. mystica in our phylogeny. By checking the original literature of these sequences, P. mystica was further found to act as an endophyte in a broad range of host plants including Aegiceras, Cinnamomum, Dendrobium and Lindera, probably lurking in the tissues of the host plants as invisible mycelium in most cases and only producing visible ascomata following senescence of the host tissues. Such ecology and a combination of all its morphological characteristics make P. mystica recognizable from other known species of Pseudoplectania. This study contributes to the understanding of the species diversity and lifecycle of Pseudoplectania.

Selliguea quinquefida (Polypodiaceae), a new calciphilous species from Guangxi, China, is described and illustrated. The new species is the second within the genus with simple and palmate fronds and unique in having simple laminae with cordiform bases. It grows in a peculiar habitat with its rhizome creeping deeply within hardened chalky soils on limestone under relatively dry conditions and always bears palmately 5-lobed fronds with pentagonal shape when fully developed. The differences and habitats among S. quinquefida and all other species with palmate fronds in the genus are discussed.

The tribe Gratioleae is the richest in species of the family Plantaginaceae, with 30 genera and more than 300 species growing mainly in South America, which could be considered a center of diversity. Argentina is one of the countries with the largest number of species (35 belonging to 6 genera) of the tribe. Although the Argentinean Flora and a checklist have been published, both are outdated. With this background, we presented an updated summary of the diversity of species belonging to the tribe Gratioleae in Argentina, with detailed analysis of their geographic distribution, their conservation status according to the categories established by the International Union for Conservation of Nature (IUCN), as well as an exhaustive study on the distribution of their richness and threat patterns in different ecoregions of the country. In addition, an evaluation of the proportion of threatened species in relation to Argentina’s Protected Areas (PAs) was evaluated. The results showed that species of Gratioleae were present in 14 ecoregions, distributed predominantly in the Humid and Dry Chaco, and the Alto Paraná Atlantic Forest. Eighteen species of the 37 Argentine taxa, including two endemic taxa, are categorized as threatened (VU, EN, or CR) (47%). Although some of these species are partially protected due to their distribution in PAs, others lack this protection. Our findings contribute to the knowledge of the geographic distribution of Gratioleae within the Argentine flora, and its conservation status.

A new poroid wood-inhabiting fungus in the Polyporales, Luteoporia tenuissima, from southwest China, is described based on morphological and molecular evidence. Luteoporia tenuissima is characterized by annual, resupinate basidiomata with lemon chrome pores when fresh, becoming cinnamon buff when dry, tissues becoming purple in KOH, a monomitic hyphal system, generative hyphae thick-walled and bearing clamp connections, and ellipsoid, smooth basidiospores measuring 2.9–3.8 × 1.9–2.4 µm. The phylogenetic analysis based on ITS + nLSU rDNA sequences shows that the new species belongs to Luteoporia, forming a monophyletic lineage with strong support, clustering with L. albomarginata and L. citriniporia. Both morphological characteristics and molecular phylogeny confirm the placement of the new species within the genus Luteoporia. A full description, illustration, phylogeny of the new species, and comparisons with morphologically similar or phylogenetically related species are provided. In addition, an identification key is provided for the currently known Luteoporia species.
根据形态学和分子证据，描述了多孔菌目中的一种新的多孔木栖真菌--Luteoporia tenuissima，它产于中国西南部。Luteoporia tenuissima 的特征是一年生复杯状基生菌，新鲜时有柠檬铬色气孔，干燥时变为肉桂色，组织在 KOH 溶液中变为紫色，单生菌丝系统，生成菌丝厚壁且有夹持连接，基生孢子椭圆形，光滑，大小为 2.9-3.8 × 1.9-2.4 µm。基于 ITS + nLSU rDNA 序列的系统进化分析表明，该新种属于 Luteoporia，与 L. albomarginata 和 L. citriniporia 形成单系，且支持度很高。形态特征和分子系统进化都证实了该新种属于 Luteoporia 属。本文提供了新种的完整描述、插图、系统发育以及与形态相似或系统发育相关物种的比较。此外，还为目前已知的 Luteoporia 物种提供了识别钥匙。

Hesperis sivasica, from the Kangal district of Sivas Province in inner Anatolia (Türkiye), is described as a new species based on morphological and molecular evidence. Although it is not morphologically closely related to the known species of Hesperis, it resembles H. kotschyi in trichome types but differs from it in pedicel, flowers, and fruit characteristics. In molecular phylogenetic analyses based on the Nuclear-encoded ribosomal internal transcribed spacer (ITS) region, H. sivasica belongs to the same clade as H. bottae and H. thyrsoidea, but it is easily distinguishable from both species based on life form, trichome types, flowers, and fruit characters. Diagnostic morphological characters, full description, SEM microphotographs, and detailed field photographs are provided. Remarks on the new species' habitat, ecology, phenology, distribution, and conservation status are also given.
Hesperis sivasica 是基于形态学和分子证据描述的一个新物种，产于内安纳托利亚（土耳其）锡瓦斯省的 Kangal 地区。虽然它在形态上与已知的 Hesperis 物种并无密切联系，但在毛状体类型上与 H. kotschyi 相似，但在花梗、花和果实特征上与之不同。在基于核编码核糖体内部转录间隔区（ITS）的分子系统学分析中，H. sivasica 与 H. bottae 和 H. thyrsoidea 属于同一支系，但根据生活形态、毛状体类型、花和果实特征，它很容易与这两个种区分开来。本文提供了诊断性形态特征、完整描述、扫描电镜显微照片和详细的野外照片。此外，还介绍了该新种的生境、生态、物候、分布和保护状况。

This study introduces a new species of Kirschsteiniothelia from Agumbe in the central Western Ghats of Karnataka, India. This new species differs from the allied species by its reduced to sessile conidiophores and cylindrical, straight to flexuous, coarsely verrucose to granulate to punctate, 18–41 euseptate elongated conidia. Phylogenetic analyses of combined ITS, LSU and SSU sequence data delineated K. agumbensis as a new lineage allied to Kirschsteiniothelia rostrata under the family Kirschsteiniotheliaceae. Furthermore, pairwise homoplasy index of phylogenetically closely related taxa also confirmed it as a new species.

Furthermore, pairwise homoplasy index of phylogenetically closely related taxa also confirmed it as a new species.","PeriodicalId":506155,"journal":{"name":"Phytotaxa","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141122760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
