These fungi possess a broad ecological distribution, causing infections in a wide diversity of hosts, spanning the animal and plant kingdoms. The spectrum of human fusariosis encompasses superficial lesions like keratitis and onychomycosis to invasive fungal diseases. Notable genera within the medically relevant fusarioid group include &lt;i&gt;Neocosmospora, Fusarium s. str.&lt;/i&gt;, and &lt;i&gt;Bisifusarium&lt;/i&gt;. While &lt;i&gt;Neocosmospora&lt;/i&gt; species (formerly &lt;i&gt;F. solani&lt;/i&gt; species complex) are primary causative agents of human fusariosis, instances involving &lt;i&gt;Fusarium s. str.&lt;/i&gt; and &lt;i&gt;Bisifusarium&lt;/i&gt; (formerly &lt;i&gt;F. dimerum&lt;/i&gt; species complex) have been reported. There is an urgent need for DNA-based markers to explore the epidemiology of these emerging fusarioid pathogens using molecular methods. We took advantage of fusarioid genomes available in NCBI (n = 20) to optimize the development of novel amplified fragment length polymorphism (AFLP) markers by conducting in-depth &lt;i&gt;in silico&lt;/i&gt; analyses to refine their applicability for studies on these pathogens' genetic epidemiology. &lt;i&gt;In-silico&lt;/i&gt; screening highlighted eight primer pair combinations (C1-C8) to be tested &lt;i&gt;in vitro&lt;/i&gt;. The AFLP protocol was used for genotyping 40 medically relevant fusarioid fungi. Based on the overall scored AFLP markers (77-93 fragments), the values of polymorphism information content (&lt;i&gt;PIC&lt;/i&gt; = 0.3474-0.3725), marker index (&lt;i&gt;MI&lt;/i&gt; = 0.0038-0.0056), effective multiplex ratio (&lt;i&gt;E&lt;/i&gt; = 26.3750-40.4750), resolving power (&lt;i&gt;Rp&lt;/i&gt; = 40.1500-54.6000), discriminating power (&lt;i&gt;D&lt;/i&gt; = 0.7978-0.8857), expected heterozygosity (&lt;i&gt;H&lt;/i&gt; = 0.4476-0.4949), and mean heterozygosity (&lt;i&gt;H&lt;/i&gt; &lt;sub&gt;avp&lt;/sub&gt; = 0.0001) demonstrated the utility of these primer combinations for discriminating &lt;i&gt;Neocosmospora, Fusarium s. str&lt;/i&gt;., and &lt;i&gt;Bisifusarium&lt;/i&gt; species. Of relevance, some AFLP panels were better than others at studying genetic trends in &lt;i&gt;Neocosmospora&lt;/i&gt; (#2 EcoRI-AT/MseI-TA, #3 EcoRI-AA/MseI-TT, and #5 EcoRI-AT/MseI-AG) or &lt;i&gt;Fusarium s. str.&lt;/i&gt; (mainly #2 EcoRI-AT/MseI-TA and #6 EcoRI-GA/MseI-TT) and &lt;i&gt;Bisifusarium&lt;/i&gt; (#1 EcoRI-GA/MseI-AG and #6 EcoRI-GA/MseI-TT), and these combinations will better resolve disease transmission routes. Our DNA fingerprint assay has proven effective by exhibiting rapidity, reproducibility, and high discriminatory capabilities, which represents a valuable asset in the ongoing efforts to combat fusariosis and enhance our scientific understanding of medically relevant &lt;i&gt;Fusarium&lt;/i&gt; and allied fusarioid genera. &lt;b&gt;Citation:&lt;/b&gt; Monteiro RC, Yu CZ, Dolatabadi S, Hagen F, Sandoval-Denis M, Crous PW, Fisher MC, Gonçalves SS, de Camargo ZP, Hofling-Lima AL, Rodrigues AM (2025).

However, due to the high variability and inconsistency of morphological traits in <i>Trichiales</i>, no taxonomic decision has yet been proposed to rectify this situation. A thorough revision of the genus is necessary. To address this, we present results of the extensive taxonomic and geographic sampling of the genus by incorporating sequences of two marker genes from 192 specimens of <i>Arcyria</i> spp. from 19 countries and six continents into the existing three gene phylogenetic backbone of <i>Trichiales</i>. Our phylogenies decisively confirm the polyphyletic nature of <i>Arcyria</i>, with a considerable part of the genus forming a sister clade to <i>Hemitrichia</i>. Consequently, we erect here the new family <i>Hemitrichiaceae</i> and resurrect the genus <i>Heterotrichia</i> to accommodate the second major branch of former <i>Arcyria</i> species.

Lectotypes and epitypes are designated for <i>Lepiota carinii</i> and <i>Echinoderma perplexum</i>. <i>Echinoderma asperum</i> as currently circumscribed is shown to be a complex formed by at least four distinct clades. The re-assessment and emendation of the sections in <i>Lepiota</i> confirm that the microstructure of the pileus covering is the taxonomically most significant character, while the shape of the basidiospores is less uniform within the sections. <b>Citation:</b> Sarawi S, Piepenbring M, Reschke K (2025).
