Recently, many new <i>Amanita</i> species have been described worldwide, increasing the genus richness. However, several clades have cryptic diversity, and many species complexes have not yet been resolved. This is the case of the rubescent species in the <i>Validae</i> section, which have been widely cited under the name <i>Amanita rubescens</i> s.l. We used a four-locus matrix (nuc rDNA internal transcribed spacer [ITS] and 28S regions and genes for RNA polymerase II subunit 2 [<i>rpb2</i>], translation elongation factor 1-α [<i>tef1-α</i>], and β-tubulin [<i>tub2</i>]) to solve the phylogenetic relationships within the <i>Amanita</i> section <i>Validae</i>. To analyze the diversity and distribution patterns of species, we used an extensive ITS sequence sampling including environmental DNA databases. The phylogenetic analyses demonstrated that the <i>Validae</i> section is divided into three monophyletic and highly supported major clades: <i>Mappae, Validae</i>, and <i>Rubescentes</i>. At least 11 species-level clades within the <i>Rubescentes</i> clade were highly supported: <i>A. cruentilemurum</i> nom. prov. <i>A. brunneolocularis, A. rubescens</i> s.s.

Nevertheless, studies focusing specifically on the spatial and temporal distribution patterns of myxomycete diversity are relatively limited, with even fewer investigating the mechanisms driving the generation and maintenance of myxomycete diversity. Therefore, this study selected two geographically distant sampling sites within northern Chinese forests to investigate myxomycete species composition, community structure, environmental drivers, and assembly patterns under geographic barriers. We established plots in the Altai Mountains (ALE) and the Greater Khingan Mountains (GKM), gathered bark and litter, and conducted 80-day moist chamber cultures of myxomycetes. Additionally, myxomycete specimens were collected in the field simultaneously to supplement the data set. This study collected 541 myxomycete specimens belonging to 73 species from 28 genera, spanning 12 families and eight orders. The ALE and the GKM had 20 identical species, accounting for 27% of the total species. Myxomycetes from both regions exhibited abundant occurrence 18 days after cultivation, with the quantity on bark substrates notably higher than on litter. <i>Arcyria pomiformis</i> and <i>Comatricha elegans</i> were the most common species in moist chamber cultures. Mantel test outcomes revealed that environmental factors had no significant impact on myxomycete community similarity between the two areas, aligning with findings from the neutral community model analysis, indicating a predominant influence of stochastic processes on myxomycete community structure in moist chamber cultures.

For instance, bioherbicides (Phoma and BioPhoma) were recently registered in Canada and the USA for the control of some perennial dicotyledonous weeds in lawns. These products are based on strains of the fungus <i>Didymella macrostoma</i> (syn. <i>Phoma macrostoma</i>) that causes white tip disease (WTD) in Canada thistle (<i>Cirsium arvense</i>). In this study, WTD was reported for the first time in the Russian Federation. Analysis of the internal transcribed spacer (ITS) region of nuc rDNA and secondary metabolite profiling confirmed the identity of Russian WTD isolates to Canadian biocontrol strains identified as <i>D. macrostoma</i>. Multilocus phylogenetic analysis based on sequencing of the ITS region, partial large subunit nuc rDNA region (28S), RNA polymerase II second largest subunit gene (<i>rpb2</i>), and partial β-tubulin gene (<i>tub2</i>) has differentiated the WTD isolates from <i>C. arvense</i> and <i>D. macrostoma</i> isolates from other plant hosts. Based on phylogenetic, morphological, and chemotaxonomic features, these WTD isolates were described as a new species named <i>Didymella baileyae</i>, sp. nov. This study also demonstrated the low pathogenicity of the ex-type <i>D. baileyae</i> isolate VIZR 1.53 to <i>C. arvense</i> seedlings and its asymptomatic development in the leaves of aboveground shoots. The organic extracts from mycelium and culture filtrate of <i>D. baileyae</i>, as well as macrocidin A and macrocidin Z, displayed phytotoxicity both to <i>C. arvense</i> leaves and seedlings. Macrocidin A was only detected in the naturally infected leaf tissues of <i>C. arvense</i> showing WTD symptoms. Macrocidins A and Z demonstrated low antimicrobial and cytotoxic activities, exhibiting no entomotoxic properties.
