Knowledge of the distribution and occurrence of aphyllophoroid and heterobasidioid fungi in Finland is continuously expanding. Here, we present 26 species new to Finland: Amylocorticium laceratum (Litsch.) Hjortstam & Ryvarden, Artomyces piperatus (Kauffman) Jülich, Basidiodendron glaucum Spirin & K.H. Larss., Basidiodendron globisporum Spirin & Malysheva, Clavariadelphus mucronatus Wells & Kempton, Clavulina perplexa E. Campo, Franchi & M. Marchetti, Clavulina reae Olariaga, Dichostereum effuscatum (Cooke & Ellis) Boidin & Lanq., Elaphocephala iocularis Pouzar, Gloeocystidiellum kenyense Hjortstam, Helicogloea pellucida Spirin & Malysheva, Hirticlavula elegans J.H.Petersen & Læssøe, Lindtneria leucobryophila (Henn.) Jülich, Luellia furcata K.H.Larss. & Hjortstam, Myxarium crystallinum D.A.Reid, Myxarium fugacissimum (Bourdot & Galzin) Malysheva & Spirin, Myxarium grilletii (Boud.) D.A.Reid, Myxarium minutissimum (Höhn.) Spirin & Trichies, Paullicorticium globosum Oberw., Polyozellus flavovirens (Höhn. & Litsch.) Svantesson & Kõljalg, Protoacia delicata V. Spirin & V. Malysheva, Ramariopsis hirtipes (Fr.) Corner, Repetobasidium conicum (Oberw.) J. Eriksson & Hjortstam, Serendipita vermifera (Oberw.) P. Roberts, Thujacorticium zurhausenii (Bres.) Nakasone, and Tretomyces lutescens (J. Erikss. & Ryvarden) K.H. Larss., Kotir. & Saaren. We also report 132 new records of 79 rare or seldom collected species, and 137 species new to a specific subzone of the boreal forest vegetation zone in Finland. These records contain notes on the substrata and the ecology and distribution of the species new to Finland are briefly discussed.
It is well-known that over-harvesting of timber threatens saproxylic fungal diversity. However, quantifying species loss is difficult due to the lack of spatial explicit baseline studies and related continuous temporal investigations. The first step to achieve basic information are systematic inventories in a given area. The Hyrcanian forest is among the most important forest biodiversity hotspots in Iran, which has been added to the UNESCO World Heritage List in 2019. Therefore, we collected 193 samples of wood-inhabiting fungi based on systematic surveys considering all seasons in Hyrcanian old-growth forests during five years (2016-2021). Species collected belonged to the fungal phylum Basidiomycota (169 species, 99 genera, 48 family and 1 incertae sedis family, 11 orders and 3 classes) and Ascomycota (24 species, 17 genera, 12 family, 6 orders and 4 classes). One collected species fall within the kingdom Protozoa, Lycogala epidendrum. 58 species and 16 genera were new for the Iranian funga; 11 and seven species were new for Gilan and Mazandaran province respectively; 20 species and one genus were new for Golestan province and one genus was a new record for the Hyrcanian forests funga. Our inventory highlights the need for documenting saproxylic fungi and to quantify the diversity in hotspot regions. This inventory might serve as a baseline for further studies to track diversity change due to forest management and climate change and to provide concepts to prevent fungal diversity from future loss.
This work summarize the results of Myxomycetes collections carried out by European and South American researchers on Antarctic ice free areas during the last fifty years. An annotated list and an identification key for the nine species with confirmed occurrence on the continent are presented.
Abstract: Currently described as part of Hymenogastraceae, Gymnopilus comprises up to 200 species distributed around the world, and 23 of these are found in Brazil. In this study, we discovered interesting specimens of G. dilepis growing with Zoysia japonica (Poaceae) grass in an urban area in the State of Paraíba. Originally described from Sri Lanka, this report treats a new and interesting record of this entity from Brazil. We also discuss whether to consider G. lepidotus as a synonym of G. dilepis based on morphological and phylogenetic evidence. Thus, as conclusion we prefer to maintain them as distinct entities and our material as G. dilepis based on morphological and ecological aspects.
Abstract: We studied systematically herbaria lichen specimens collected from Finland and from former Finnish parts of Russia to detect lichenicolous fungi. In total, 3355 lichen specimens were found with lichenicolous fungi from 160 taxa. We report here 27 species and three genera that are new to Finland. Three of these, Cercidospora epithamnolia, Cyclothyrium sp. and Roselliniella stereocaulorum, are reported as also new to Scandinavia. Three taxa are reported from a new host.
