24Mushroom-forming fungi in the order Agaricales represent an independent origin of 25 bioluminescence in the tree of life, yet the diversity, evolutionary history, and timing of 26 the origin of fungal luciferases remain elusive. We sequenced the genomes and 27transcriptomes of five bonnet mushroom species (Mycena spp.), a diverse lineage 28comprising the majority of bioluminescent fungi. We show that bioluminescence 29 evolved in the common ancestor of Mycena spp. and the marasmioid clade of 30Agaricales and was maintained through at least 160 million years of evolution. We 31revealed Mycena exhibit two-speed genomes and resolve how the luciferase cluster was 32 derived by duplication and translocation, frequently rearranged and lost in most Mycena 33 species, but conserved in the Armillaria lineage. Luciferase cluster members were co-34 expressed across developmental stages, with highest expression in fruiting body caps 35and stipes, suggesting fruiting-related adaptive functions. Our results contribute to 36 understanding a de novo origin of bioluminescence and the corresponding gene cluster 37 in a diverse group of enigmatic fungal species. 38

“…With taxonomic descriptions dating back to the 1700s (Vahl 1790), A. mellea was believed to be a highly polymorphic pathogen until the species complex began to be unravelled in the late 1970s, revealing approximately 40 described species with lifestyles that range from saprotrophic to pathogenic (Korhonen, 1978, Anderson and Ullrich, 1979, Rishbeth, 1982, Watling et al., 1991, Volk and Burdsall, 1995). Fungi in this genus produce a range of unique secondary metabolites and are unusual within the basidiomycetes in that their persistent vegetative state is diploid rather than dikaryotic (Korhonen & Hintikka 1974, Shim et al 2006, Misiek et al., 2011, Mihail, 2015). Most, if not all, Armillaria species are bioluminescent, with Armillaria being one of three fungal lineages responsible for the ‘fox fire’ phenomenon that has been described for millennia.…”

“…Light in the range of 520–530 nm is emitted from the mycelium growing in decaying wood, which can cause the entire forest floor to appear aglow. Bioluminescence is only apparent in hyphae and rhizomorphs and has not been observed in fruiting bodies (Murrill, 1915, Ramsbottom, 1953, Desjardin et al., 2008, Mihail, 2015). Armillaria mushrooms are edible, although it is advisable to cook them thoroughly beforehand to avoid stomach upsets, and some work has been done toward realising their commercial cultivation (Shim et al.…”

Fungi are often inconspicuous in nature and this means it is all too easy to overlook their importance. Often referred to as the “Forgotten Kingdom”, fungi are key components of life on this planet. The phylum Basidiomycota, considered to contain the most complex and evolutionarily advanced members of this Kingdom, includes some of the most iconic fungal species such as the gilled mushrooms, puffballs and bracket fungi. Basidiomycetes inhabit a wide range of ecological niches, carrying out vital ecosystem roles, particularly in carbon cycling and as symbiotic partners with a range of other organisms. Specifically in the context of human use, the basidiomycetes are a highly valuable food source and are increasingly medicinally important. In this review, seven main categories, or ‘roles’, for basidiomycetes have been suggested by the authors: as model species, edible species, toxic species, medicinal basidiomycetes, symbionts, decomposers and pathogens, and two species have been chosen as representatives of each category. Although this is in no way an exhaustive discussion of the importance of basidiomycetes, this review aims to give a broad overview of the importance of these organisms, exploring the various ways they can be exploited to the benefit of human society.

“…The mechanisms of host infection as well as hostpathogen interactions have been studied intensively [3][4][5][6][7]. In addition, Armillaria mushrooms attract a wider interest, for instance, as the worldʼs biggest living organism [8] or as a producer of bioluminescence [9]. A broad variety of antibacterial and cytotoxic sesquiterpene aryl esters were isolated from the genus Armillaria, especially Armillaria mellea [10][11][12][13][14][15][16][17][18][19][20], but also Armillaria novae-zelandiae [21] and Armillaria tabescens [22].…”

IntroductionDuring our investigations of biologically active fungi, Armillaria ostoyae (Romagn.) Herink [1], a basidiomycete belonging to the family Physalacriaceae, came into focus, as it affected degranulation in RBL-2H3 cells. The species is commonly known as edible mushroom, but it also occurs as a devastating pathogen of various tree species causing serious economic losses in forestry all over the world [2]. The mechanisms of host infection as well as hostpathogen interactions have been studied intensively [3][4][5][6][7]. In addition, Armillaria mushrooms attract a wider interest, for instance, as the worldʼs biggest living organism [8] or as a producer of bioluminescence [9]. A broad variety of antibacterial and cytotoxic sesquiterpene aryl esters were isolated from the genus Armillaria, especially Armillaria mellea [10][11][12][13][14][15][16][17][18][19][20], but also Armillaria novae-zelandiae [21] and Armillaria tabescens [22]. In this manuscript, degranulation inhibiting effects of extracts from fruiting bodies and cultivated mycelium as well as bioactivity-guided isolation of compounds from the mycelium of A. ostoyae are described. Degranulation is the process in which cells release secretory products stored in secretory granules by exocytosis. It is an important feature of many immune cells, e.g., for release of mediators [23]. Inhibition of degranulation can result in the blocking of inflammatory or allergic reactions.
