Although fusarioid fungi have been implicated in citrus diseases worldwide, their diversity and pathogenic potential on citrus in China remain poorly characterized. To investigate their species diversity, extensive field surveys were conducted in several citrus-producing regions of China between 2021 and 2024. Symptomatic tissues exhibiting dieback, necrosis, gummosis, canker, and wood decay were collected from twigs, branches, and trunks. Based on multi-locus phylogenetic analyses and morphological characteristics, 336 fusarioid isolates from eight provinces were assigned to six <i>Fusarium</i> species complexes and the genus <i>Neocosmospora</i>, comprising 21 known species (15 <i>Fusarium</i> spp. and six <i>Neocosmospora</i> spp.) and three novel species, namely <i>F. gummosum</i>, <i>N. reticulatae</i> and <i>N. unshiu</i>. Among the known species, 13 are reported from <i>Citrus</i> spp. for the first time, and two represent new records for China. Pathogenicity tests revealed that most fusarioid isolates were pathogenic to citrus branches, with <i>N. unshiu</i> and <i>F. asiaticum</i> being the most aggressive, inducing gummosis and cortex and xylem necrosis, consistent with symptoms observed in the field. Notably, <i>N. unshiu</i> was found to be the dominant pathogen causing citrus trunk canker in Hanzhong City, Shaanxi Province, where it is widely distributed and causes significant damage to citrus. To our knowledge, this study represents the first comprehensive investigation of fusarioid fungi associated with citrus branch diseases in China and provides a basis for future pathogen monitoring, disease prevention, and management strategies. <b>Citation:</b> Xiao XE, Cheng MJ, Zheng F, Ao YJ, Deng JR, Crous PW, Jiao C, Li HY (2025).

In this study, we address longstanding questions about the evolution, systematics, and trophic mode of these fungal genera. We used high-throughput sequencing and a custom genome assembly pipeline to sequence and assemble 41 new genomes of epigeous and hypogeous <i>Morchellaceae</i> genera and outgroup taxa from the sister family <i>Discinaceae</i>.

They are known as zombie-ant fungi because they manipulate the behaviour of ants, since infected ants are forced to move to specific sites in the forest, with optimal environmental conditions for the development of the fungus sporocarp or sporome and the release of the spores. Once there, the ants grab to the substrate with their mandibles, die, and their body becomes a source of nutrients for the fungus. Most of the species of the <i>O. unilateralis</i> complex have been described from the Neotropics and the East and Southeast Asia. However, it is likely that there are still many unknown species due to the diversity of their hosts and different specific associations. In this study, we describe six new species of the <i>O. unilateralis</i> complex from western Mexico: <i>O. camponoti-striati</i>, <i>O. cephalotiphila</i>, <i>O. deltoroi</i>, <i>O. haraveriensis</i>, <i>O. jaliscana</i>, and <i>O. pseudocamponoti-atricipis</i>, based on morphological characters, phylogenetic analyses of DNA sequences (18S, <i>TEF1</i>, <i>RPB1</i>, and <i>RPB2</i>), and ecological data.

In Antarctica lichens represent an important group of organisms characterized by a high percentage of endemism, which have specialized to grow on rocks, as the predominant substrate for colonization. Here, Antarctic epilithic thalli of five endemic and three cosmopolitan lichen species have been investigated for their potential role as fungal species hotspots. The culturable fraction of the Antarctic lichen-associated fungi and algae was uncovered with the aim to isolate as many species as possible and find whether taxa are strictly connected to the Antarctic environment or are cosmopolitan species that particularly associate to lichens in harsh, extreme environments. Over 300 fungal and algal inocula grew in culture, among which we recognized species previously described, as well as five new fungal species in <i>Ascomycota</i> and <i>Basidiomycota</i>, namely: <i>Petrophila complexa sp. nov</i>., <i>Dactylospora endolichenica sp. nov</i>., <i>Knufia elegansiana sp. nov</i>., <i>Pseudeurotium lichenicum sp. nov</i>., and <i>Kurtzmanomyces lichenum sp. nov</i>. These species seem to select lichens as their preferred niche, both in Antarctica and worldwide. Indeed, the major representatives of the lichen mycobiota are fungi that do not show any specificity toward a particular lichen host species, rather toward the lichen thallus in general, as a structure in which spores, yeast cells and mycelia fragments thrive or rest. Particularly in Antarctica, where conditions on rock surfaces are far more selective than elsewhere, lichen thalli would be even more exploited as suitable niches by other fungi for their evolution and diversification. <b>Citation:</b> de Carolis R, Stoppiello G, Turchetti B, Bartolomeo G, Coleine C, Tetriach M, Selbmann L, Muggia L (2025).

The distribution of <i>E. allantospora</i> and <i>M. curvata</i> remains poorly understood, as no records for these species were found in GlobalFungi. This study provides new insights into the molecular systematics, taxonomy, and biogeography of the <i>Rhamphoriales</i> and <i>Pleurotheciales</i>, and highlights the role of environmental DNA metabarcoding in uncovering fungal diversity and distribution patterns. <b>Citation:</b> Réblová M, Nekvindová J, Hernández-Restrepo M, Hradilová M, Kolařík M (2025).
