Seven field surveys were carried out in the Ailaoshan area of Yunnan Province, China, from 2016 to 2021, in which 2,814 specimens of wood-decaying fungal species were collected and identified based on morphology and phylogenetic analyses. One hundred and three wood-decaying species were identified, belonging to 64 genera, 29 families, and nine orders. Polyporales is the most abundant order in this area, accounting for 55.34% of all species, while Polyporaceae is the most abundant family, accounting for 18.45% of all species discovered in this area. The wood-decaying fungal checklist is provided according to the latest fungi classification system. Of these species, 11 are edible and therapeutic, four are forest pathogens, eight are threatened, and nine have just been reported from Ailaoshan Mountain. These species comprise 10.68%, 3.88%, 7.77%, and 8.74% of all species, respectively, while 71 species, or 68.93%, have unclear functional relationships. The sequences of the Internal Transcribed Spacer (ITS) gene region of the studied specimens were generated, and the phylogenetic analyses were performed with the maximum likelihood, maximum parsimony, and Bayesian inference methods. This study enriches the diversity of wood-decaying fungi in the Ailaoshan area. Also, it provides a theoretical basis for the future protection and utilization of wood-decaying fungal resources in this area.

When reviewing the species diversity of Dryopteridaceae from Vietnam, we noticed the name Dryopteris microlepioides Christensen (1934: 102) is taxonomically uncertain and to be treated (Hassler 1994–2024). Dryopteris microlepioides was described based on two collections from northern Vietnam and was thought to be a distinct species superficially resembling Microlepia speluncae (Linnaeus 1753: 1093) Moore (1857: 93) (Christensen 1934). Since its publication in 1934, this name had been neglected by authors who treated Dryopteris Adanson (1763: 20) for the fern flora or species diversity of Vietnam (e.g., Tardieu-Blot & Christensen 1938, 1941; Pham 1999; Phan 2010). At the first sight of the type specimens of D. microlepioides, the senior author (SYD) was aware of D. microlepioides representing the same taxon with Trichoneuron microlepioides Ching (1965: 119) described from southern Yunnan, China, because this taxon is morphologically unique by having the microlepioid frond habit (especially with copious pale hairs on both surfaces) and the dryopterioid sori (reniform, medial on abaxial surface of lamina) (Fig. 1). Phylogenetically, the sample of this species from northern Vietnam, which was identified as T. microlepioides by Liu et al. (2016), was resolved to be sister to Polystichopsis (Smith 1875: 217) Holttum (1947: 147) in Dryopteridaceae subfam. Polybotryoideae based on the analysis of three cpDNA sequences (rbcL, atpA, and atpB) (Liu et al. 2016). In recent years, we also collected this taxon in northern Vietnam (paratype locality of D. microlepioides) and southern Yunnan, China, and conducted phylogenetic analysis based on cpDNA genome (not presenting here). Our analysis resolved one sample from Vietnam (Dong 4598) and two collections from Yunnan (Dong 4801 and Zuo 5093) clustered together, identifying no any significant difference between them. The three samples in the phylogenetic tree formed a sister relationship in high supporting values with Polystichopsis as the result in Liu et al. (2016). This result provides further evidence supporting the same species of D. microlepioides Christensen (1934) with T. microlepioides Ching (1965).

Volvariella griseoalba is described as a new species from Punjab, Pakistan. The species was separated from its morphologically closest relative, V. sathei by its shiny greyish-white, umbonate pileus, subglobose to broadly ellipsoid basidiospores, utriform cheilocystidia and a white to brown volva. Molecular phylogenetic analyses of ITS and LSU region of the nrDNA also supported the studied taxon as a distinct species in Volvariella.

While conducting a seasonal assessment of the Mula-Mutha River basin in Maharashtra, India, an unknown taxon of the genus Geissleria was observed from an oligotrophic stream connected to the Mutha River. This taxon is described here as new to science based on detailed light and scanning electron microscopic observations. The characteristics of this new species used to assign it to the genus Geissleria include triundulate valve margins, a straight and filiform raphe structure, lineolate striae, and the presence of annuli a circular or semi-circular hyaline area positioned on the valve apices. In G. triundulata sp. nov., the annulus is barely visible in light microscopy. The present study discusses the morphology of this new species compared to other Geissleria species, undertaking a thorough analysis of various morphological features observed in members of the genus Geissleria. This new taxon resembles G. lubilensis and G. fogedii in having a slightly triundulate margin but differs in their broad and protracted valve apices, holding differences from the new species. This study also presents a brief discussion concerning the ecology of the newly discovered species and the worldwide distribution of all Geissleria species.

A new species, Impatiens lhunzeensis (Balsaminaceae), and a new record of I. leptocarpa from southern Xizang, China are reported and described in this study. Based on morphological and phylogenetic evidence, both I. lhunzeensis and I. leptocarpa are assigned to I. sect. Racemosae. The new species forms a clade with I. drepanophora, I. eubotrya and I. principis, while I. leptocarpa is phylogenetically close to I. radiata and I. harae. The new species has a sympatric distribution with and is morphologically similar to both I. radiata and I. harae, but differs by the hairy stem, the densely hairy leaf blade, the raceme inflorescence, the reniform dorsal petals, the navicular lower sepal, the broadly ovate to sub-orbicular upper petals and the triangular oblong lower petals.

Hyphoderma is one of the most important representative groups of wood-inhabiting fungi. These fungi secrete various enzymes capable of degrading cellulose, hemicellulose, and lignin into simple inorganic substances. The taxa within the genus cause the white rot of wood, play a key role in the carbon cycle, and are the most efficient wood decomposers in the forest ecosystem. This study proposes a new wood-inhabiting fungal taxon, Hyphoderma guangdongense, based on morphological features and molecular evidence. It is characterized by the white hymenial surface, a monomitic hyphal system having the generative hyphae with clamp connections, the presence of the septate and tubular cystidia, and cylindrical basidiospores (6–10 × 3–5 µm). The phylogenetic tree inferred from a combination of the internal transcribed spacers (ITS) and large subunit (nrLSU) of the nuclear ribosomal DNA (rDNA) sequences revealed that H. guangdongense placed into the genus Hyphoderma, in which it is closely related to a clade comprising two taxa, H. setigerum, and H. floccosum. A full description, illustrations, and results of the new species' phylogenetic analysis are provided.
真菌是栖息在木材中的真菌中最重要的代表类群之一。这些真菌能分泌各种酶，将纤维素、半纤维素和木质素降解成简单的无机物。该属的类群会导致木材白腐，在碳循环中扮演重要角色，是森林生态系统中最有效的木材分解者。本研究根据形态特征和分子证据，提出了一个新的木材栖息真菌类群--广东白腐菌（Hyphoderma guangdongense）。其特征是菌膜表面为白色，单生菌丝系统中的生成菌丝具有钳状连接，存在隔膜和管状子囊孢子，基生孢子为圆柱形（6-10 × 3-5 µm）。根据核糖体 DNA（rDNA）序列的内部转录间隔（ITS）和大亚基（nrLSU）组合推断出的系统发生树显示，广东鸡冠花被归入鸡冠花属（Hyphoderma），与由 H. setigerum 和 H. floccosum 两个类群组成的支系关系密切。本文提供了对该新种的完整描述、图解和系统发育分析结果。

This is a morphological study of 108 accessions of Solanum campylacanthum and 10 accessions of Solanum cerasiferum. The aim was to assess the morphological variations that occur within the S. campylacanthum species in Uganda and evaluate the morphological differences between S. campylacanthum and S. cerasiferum. Fourteen quantitative and eleven qualitative vegetative characters were measured and analysis done by phenetics method. Cluster (UPGMA) and box plot analyses were done in PAST program version 4.03. Prickle density and leaf tip angles are reported for the first time as being useful in the intraspecific delimitation of S. campylacanthum. The distinction between S. cerasiferum and S. campylacanthum can only be based on leaf base shapes, which is, attenuate and oblique respectively.
这是一项形态学研究，研究对象是 108 个 Campylacanthum Solanum 和 10 个 cerasiferum Solanum。目的是评估乌干达 S. campylacanthum 品种内部的形态变异，并评估 S. campylacanthum 和 S. cerasiferum 之间的形态差异。研究人员测量了 14 个定量植被特征和 11 个定性植被特征，并采用表观遗传学方法进行了分析。聚类（UPGMA）和箱形图分析由 PAST 程序 4.03 版完成。首次报告了刺密度和叶尖角在 S. campylacanthum 的种内划分中的作用。S. cerasiferum 和 S. campylacanthum 之间的区别只能基于叶基部的形状，即分别是渐狭型和偏斜型。

Fourteen quantitative and eleven qualitative vegetative characters were measured and analysis done by phenetics method. Cluster (UPGMA) and box plot analyses were done in PAST program version 4.03. Prickle density and leaf tip angles are reported for the first time as being useful in the intraspecific delimitation of S. campylacanthum. The distinction between S. cerasiferum and S. campylacanthum can only be based on leaf base shapes, which is, attenuate and oblique respectively.","PeriodicalId":20114,"journal":{"name":"Phytotaxa","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141804735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

New synonyms and lectotypes in Sida sect. Cordifoliae (Malvaceae, Malveae) are proposed here and reveal the first record and extension of the distribution area of Sida maculata to the Brazilian semi-arid region. The species was first described in the 18th century for the Caribbean islands of Cuba and the Dominican Republic and for a long time was confused with S. cordifolia, from which it is unquestionably distinct in its leaves, inflorescences and flowers. In Brazil, S. maculata is widely distributed from Maranhão to the north of Minas Gerais and was identified for almost a century in herbaria and local floristic treatments as S. galheirensis. Discussions and photographs of types of S. maculata and related taxa are presented, as well as an updated map of the species’ geographical distribution.
本文提出了 Sida sect.Cordifoliae (Malvaceae, Malveae)中的新异名和讲座型，首次记录并揭示了 Sida maculata 在巴西半干旱地区的分布范围。该物种最早于 18 世纪被描述于加勒比海的古巴和多米尼加共和国，长期以来一直与 S. cordifolia 混淆，而 S. cordifolia 的叶、花序和花无疑与 S. cordifolia 截然不同。在巴西，S. maculata 广泛分布于马拉尼昂州到米纳斯吉拉斯州北部地区，近一个世纪以来一直被标本馆和当地花卉学界认定为 S. galheirensis。本文介绍了 S. maculata 及相关类群的类型讨论和照片，以及该物种的最新地理分布地图。
