- In this 7th contribution to the Fungal Systematics and Evolution series published by Sydowia, the authors formally describe 14 species: Cantharomyces paschalis, Cryptandromyces pinguis, C. tricornis, Laboulbenia amblystomi (Laboulbeniales); Cortinarius squamosus, Entoloma brunneicoeruleum, E. callipygmaeum, E. minutigranulosum, E. perasprellum, E. pulchripes, E. tigrinum, E. timidum, E. violaceoserrulatum (Agaricales); and Suillus quercinus (Boletales). The following new country records are reported: Crepidotus malachioides from Italy, Leucoagaricus mucrocystis from French Guiana, Pluteus multiformis from Turkey (Agaricales); Herpomyces periplanetae from Benin, the D.R. Congo, and Togo (Herpomycetales); Melanustilospora ari from Pakistan (Urocystidales); Neopestalotiopsis clavispora causing fruit rot on Zizyphus mauritiana from India (Amphisphaeriales); and Phytopythium chamaehyphon and Pp. litorale from Brazil (Peronosporales). Finally, a new combination is proposed based on morphology, ecology, and phylogenetic analysis: Rhodocollybia asema (Agaricales).

- As currently delineated, Hygrophorus sect. Olivaceoumbrini is a polyphyletic assembly within subg. Colorati, encompassing glutinous and pigmented taxa. According to available literature, between a dozen and twenty species may belong in the section, mostly represented in continental and boreal forests of Europe and North America. However, the limited phylogenetic and biogeographic coverage of the genus does not presently allow for a reliable assessment of its taxonomic boundaries, nor does it provide a complete picture of species diversity within sect. Olivaceoumbrini. In an ongoing effort to confer an evolutionary backbone to Hygrophorus systematics, we assembled and analysed a dataset comprising 268 intercontinental sequences, including holotypes of 7 taxa previously not positioned phylogenetically, and enriched with collections from largely unexplored Mediterranean and Anatolian ecosystems. Overall, 30 clades are identified within 5 distinct lineages, including 11 species putatively new to science. Seven of these are formally described here as H. agathosmoides, H. albofloccosus, H. canadensis, H. limosus, H. marcocontui, H. pinophilus and H. pustulatoides spp. nov. This enriched coverage of section Olivaceoumbrini s.lat. calls for a re-evaluation of its natural boundaries into a core monophyletic clade, including H. olivaceoalbus and five closely related lookalikes, as well as the assignment of the section rank to the four remaining lineages: sect. Fuscocinerei sect. nov., sect. Limacini sect. nov., sect. Nudolidi sect. nov. and sect. Tephroleuci, respectively. We also stabilize the usage of six historical names, H. glutinifer, H. hyacinthinus, H. mesotephrus, H. olivaceoalbus, H. pustulatus and H. tephroleucus, through designation of two neotypes, three lectotypes and four epitypes.
