Aglaonema modestum (Araceae) is an evergreen herbage which is intensively grown as an ornamental plant in South China. A new disease was observed in A. modestum from 2020 to 2021 in Guangdong province, China. The disease symptoms associated with plants were initial leaf wilt, stem rot and resulting plant death while leading to severe economic losse...

The global diversity of fungi has been estimated using several different approaches. There is somewhere between 2–11 million estimated species, but the number of formally described taxa is around 150,000, a tiny fraction of the total. In this paper, we examine 12 ascomycete genera as case studies to establish trends in fungal species descriptions,...

Leptosphaeriaceae, a diverse family in the order Pleosporales, is remarkable for its scleroplectenchymatous or plectenchymatous peridium cells. Four Leptosphaeriaceae species were discovered and studied during the investigation of saprobic fungi from plant substrates in China. Novel taxa were defined using multiloci phylogenetic analyses and are su...
Article
Fungi play vital roles in ecosystems as endophytes, pathogens and saprobes. The current estimate of fungal diversity is highly uncertain, ranging from 1.5 to 12 million, but only around 150,000 species have been named and classified to date. Since the introduction of DNA based methods for species identification, the number of newly described taxa h...

Sexual reproduction is the basic way to form high genetic diversity and it is beneficial in evolution and speciation of fungi. The global diversity of teleomorphic species in Ascomycota has not been estimated. This paper estimates the species number for sexual ascomycetes based on five different estimation approaches, viz. by numbers of described f...

Three fungal specimens (two sexual and one asexual) were collected during fieldwork conducted in China, Taiwan and Thailand. Both sexual morphs share superficial, black ascomata surrounded by flexuous setae; 8-spored, unitunicate, cylindrical asci, with J+, apical ring, and ellipsoidal to allantoid, aseptate, guttulate ascospores. The asexual morph...

Species delimitation is one of the most fundamental processes in biology. Biodiversity undertakings, for instance, require explicit species concepts and criteria for species delimitation in order to be relevant and translatable. However, a perfect species concept does not exist for Fungi. Here, we review the species concepts commonly used in Basidi...

Fungi are an essential component of any ecosystem, but they can also cause mild and severe plant diseases. Plant diseases are caused by a wide array of fungal groups that affect a diverse range of hosts with different tissue specificities. Fungi were previously named based only on morphology and, in many cases, host association, which has led to su...

Leaf litter decomposition plays a vital role in the nutrient budget of forest ecosystems. Fungal communities colonising leaf litter are "key players" in decomposition and nutrient recycling, because of their ability to produce a wide range of extracellular enzymes that facilitate breakdown of leaf litter. Fungal colonization of decomposing leaf lit...

Endophytic fungi are internal inhabitants of plant tissues that do not apparently cause harm to the host. Ecologically they provide a number of benefits to the plants by decreasing herbivory, increasing drought and disease resistance and enhancing the growth of plants. Endophytes have emerged as an exciting research topic as they have the potential...

A fungus similar to the monotypic genus Natarajania, isolated from dead wood and collected in Thailand, is reported. Analysis of partial ribosomal LSU and a protein coding gene (RPB2) demonstrated that the new isolate belonged to Stilbosporaceae, Diaporthales and genetically different from N. indica. It is unique in producing synnematous conidiopho...
Article
Several genera in Xylariaceae are polyphyletic in phylogenetic trees and represent more than one distinct genus. However, it is challenging to resolve these genera that are often phylogenetically distantly related, because many taxa have never been recollected and sequenced. Those that have been named and sequenced often lack documented characters...
