Field research targeting rust diseases across Korea uncovered three distinct species of <i>Neophysopella</i>, affecting different members of the family <i>Vitaceae</i>. In our examination of both wild and cultivated grapevine (<i>Vitis</i>) species, including <i>V. amurensis</i>, <i>V. coignetiae</i>, and <i>V. vinifera</i>, we found <i>N. meliosmaemyrianthae</i> as well as a previously undescribed rust species, which we describe here as <i>N. viticola sp. nov. Neophysopella ampelopsidis</i>, which was previously identified as a rust pathogen of <i>Vitis</i> spp., has been observed to specifically infect <i>Ampelopsis brevipedunculata</i>. Through molecular sequence analysis of the ITS, LSU rDNA, and <i>cox</i>3 mtDNA regions, we determined the phylogenetic placements of these three species. Our morphological studies revealed the distinguishing features of <i>N. viticola</i>, particularly its unique teliospore layer and urediniospore dimensions. The emergence of <i>N. viticola</i> on economically valuable grapevines raises concerns about potential agricultural losses, highlighting the urgency for developing specialized management approaches in viticulture. <b>Citation:</b> Na DH, Choi Y-J, Shin H-D (2024).

Some species of multiple groups of the <i>Ascomycota</i> and the <i>Basidiomycota</i> produce different types of rhizomorphs. In the <i>Agaricales</i>, the structures are largely found in <i>Marasmiineae</i>, particularly in the <i>Omphalotaceae</i>, <i>Marasmiaceae</i>, and <i>Physalacriaceae</i>. Many rhizomorph-forming species spread over the forest floor (ground level), while others form aerial litter-trapping rhizomorph systems that hang on living branches of the forest understorey. Here, we describe three new species that form aerial systems, two in <i>Marasmius</i> and one in <i>Pusillomyces</i>, all of which inhabit areas of the Amazon rainforest in Amazonas State, Brazil. Support for these new species is based on evidence derived from morphological and molecular phylogenetic analyses using nuclear ribosomal internal transcribed spacer region (nrITS) and nuclear ribosomal large subunit (nrLSU) markers. <i>Marasmius foliauceps sp. nov</i>., with a pileipellis made up of <i>Rotalis</i>-type broom cells, is different from all other species described to date and branched along with species of the monophyletic <i>Marasmius</i> sect. <i>Marasmius</i> subsect. <i>Marasmius</i>, being conspecific with specimens from Guyana.

They all form aerial litter-trapping rhizomorph systems that mimic spider webs, particularly those hanging on the understorey. Whether made of mycelia or silk, such webs serve to capture food.

Fungal populations separated by geography are candidates for allopatric speciation, yet species connectivity typically persists because there is minimal divergence at functional parts of mating compatibility genes. We studied whether connectivity is maintained across populations of a widespread species complex of magic mushrooms that has infiltrated the Northern Hemisphere from a hypothesised centre of origin in Australasia. We analysed 89 genomes of magic mushrooms to examine erosion of species connectivity in disparate populations with support from gene flow, kinship, structure, allelic diversity, and mating compatibility. We used comparative genomics and synteny to test whether the genes that produce psilocybin are under selection in natural populations of magic mushrooms. Despite phenotypic plasticity and intercontinental distribution, sexual compatibility is maintained across geographically isolated populations of magic mushrooms. Psilocybin loci have high allelic diversity and evidence of balancing selection. Australasia is the centre of origin of wood-degrading magic mushrooms and geographically separated populations are fully sexually compatible, despite minimal gene flow since differentiation from a shared ancestor. Movement of woodchips, mulch, or plants has most likely facilitated invasion of these mushrooms in the Northern Hemisphere. <b>Citation:</b> McTaggart AR, Scarlett K, Slot JC, Barlow C, Appleyard C, Gardiner DM, Fechner N, Tilden J, Hass D, Voogelbreinder S, Lording WJ, Lloyd RA, Shuey LS, Drenth A, James TY (2024).

Based on collections made in New Zealand, East Asia and North America, this study describes a new subgenus <i>Cremeo-ochraceae</i>, the ninth subgenus of <i>Russula</i>. Even though BLASTn of the ITS sequences suggested affinities with species of subgenera <i>Russula</i> and <i>Heterophyllidiae,</i> the phylogenetic analysis based on a five-locus DNA dataset placed the target samples in an independent major clade that is taxonomically equivalent to subgenus. This multilocus analysis also obtained support for the recognition of two superclades in <i>Russula</i>, opposing subgenera <i>Glutinosae</i>, <i>Archaeae</i> and <i>Compactae</i> to the rest of the genus. The type species of the new subgenus is <i>R. cremeo-ochracea</i> from New Zealand, which is here epitypified, and the authors describe a new variety for it: <i>R. cremeoochracea</i> var. <i>myrtacearum</i>. The new subgenus also harbors a North American <i>R. cf. inopina</i> and its Asian counterpart, discovered from southwestern China, described here as <i>R. estriata sp. nov</i>. Two environmental ITS sequences, one from Japan and one from Malaysia may represent two more undescribed taxa. The new subgenus shares with subgen. <i>Brevipedum</i> subsect. <i>Pallidosporinae</i> the general field habit, the unequal lamellae and the relatively small spores with inamyloid suprahilar spot and similar spore ornamentation. It differs from the latter subsection principally in the poor contents of all types of cystidioid cells and the often areolate-scurfy pileus surface composed of slender, undulating hyphal terminations with frequent subcapitate apices. Biogeographically, subgen. <i>Cremeo-ochraceae</i> shares with <i>Multifurca</i>, another small relict lineage of <i>Russulaceae</i>, a circum-Pacific distribution pattern except for South America. Both lineages lack representatives in Europe and Africa. The hypothesis proposing an African origin for the genus is considered unlikely. <b>Citation:</b> Buyck B, Horak E, Cooper JA, Wang XH (2024).
