“…Parasitic Agaricomycetes usually infect the fruiting bodies of other fungi, although species infecting hyphae or conidia are also known (Tzean & Estey, ; Jeffries, ). Mycoparasitism is widespread within Pucciniomycotina, where it seems to be an ancestral lifestyle (Aime, Toome & McLaughlin, ; Wang et al, ; Oberwinkler, ) (Fig. ).…”

“…Basidiomycetous yeasts can be found within the Pucciniomycotina and the Ustilaginomycotina. Pucciniomycotina forms the most diverse of these yeast lineages, with the yeast lifestyle evolving independently in at least four lineages (Microbotryomycetes, Spiculogloeomycetes, Agaricostylbomycetes and Cystobasidiomycetes) (Aime, Toome & McLaughlin, ;Wang et al, ; Oberwinkler, ). Many of these lineages include dimorphic fungi that can be cultured as unicellular fungi, a trait that appears additionally in the Mixiomycetes and the Cryptomycocolacomycetes, considered as yeasts by some authors.…”

Fungal evolution: major ecological adaptations and evolutionary transitions

Fungi are a highly diverse group of heterotrophic eukaryotes characterized by the absence of phagotrophy and the presence of a chitinous cell wall. While unicellular fungi are far from rare, part of the evolutionary success of the group resides in their ability to grow indefinitely as a cylindrical multinucleated cell (hypha). Armed with these morphological traits and with an extremely high metabolical diversity, fungi have conquered numerous ecological niches and have shaped a whole world of interactions with other living organisms. Herein we survey the main evolutionary and ecological processes that have guided fungal diversity. We will first review the ecology and evolution of the zoosporic lineages and the process of terrestrialization, as one of the major evolutionary transitions in this kingdom. Several plausible scenarios have been proposed for fungal terrestralization and we here propose a new scenario, which considers icy environments as a transitory niche between water and emerged land. We then focus on exploring the main ecological relationships of Fungi with other organisms (other fungi, protozoans, animals and plants), as well as the origin of adaptations to certain specialized ecological niches within the group (lichens, black fungi and yeasts). Throughout this review we use an evolutionary and comparative-genomics perspective to understand fungal ecological diversity. Finally, we highlight the importance of genome-enabled inferences to envision plausible narratives and scenarios for important transitions.

“…To so slabo raziskane glivne skupine. Najpomembnejše značilnosti je razjasnil Couch (1931Couch ( in 1938, ki je podrobno opisal življenjski krog gliv iz rodu Septobasidium in njihovo povezanost s kaparji, kasneje pa se z njimi raziskovalno niso več ukvarjali (Oberwinkler, 2017). Kljub jasnim dokazom, da je sožitje glive iz rodu Septobasidium in kaparjev mutualistična simbioza, pa nekateri avtorji te glive vseeno prištevajo med tipične antagonistične entomopatogene glive za kaparje (Porcelli, 2013).…”

“…Bazidiospore niso sposobne okužiti gostiteljskih kaparjev. Okužbo opravijo trosi (bazidiomicetne kvasovke), ki brstijo iz bazidiospor in so zato haploidni (Oberwinkler, 2017;Henk, 2008). Okužijo se posamezne ličinke, ki se izležejo v labirintu trosnjaka.…”

Na zdravih in odmirajočih vejah gostiteljskih dreves smo z molekularnimi in morfološkimi metodami identificirali glivo Septobasidium marianii Bres. ter ugotovili, da trosnjaki glive vsebujejo kolonije rdečega hruševega kaparja (Epidiaspis leperii (Signoret 1869)). Opisane so značilnosti mutualistične simbioze, ki jo oblikujeta gliva in kaparji ter značilnosti bolezni filcavost listavcev, ki prizadene gostiteljske rastline. Navedeni so ukrepi za kontrolo bolezni, ki jih priporočajo v literaturnih virih. Prispevek predstavlja prvo poročilo o pojavu bolezni filcavosti listavcev v Sloveniji.Ključne besede: bolezen; filcavost listavcev; hruška; naši; Septobasidium marianii; Epidiaspis leperii; Slovenija Felt disease (Septobasidium marianii Bres.): an overlooked disease of fruit trees in SloveniaAbstract: We report the finding of the disease of pear (Pyrus communis 'Konferans' , ' Abate Fetel') and nashi trees (Pyrus pyrifolia 'Hosui') in the Soča river valley in the westernmost part of Slovenia (E:13.58844°, N: 46.04117°). On healthy and moribund branches of host trees, the fungus Septobasidium marianii Bres. was identified with morphological and molecular methods. In the basidiomes colonies of European pear scale (Epidiaspis leperii (Signoret 1869)) were observed. Mutualistic symbiosis formed by the fungus and the scale insects is explained and the characteristics of felt disease affecting host plants is described. Listed are the disease control measures recommended in the literature. The article is the first report of the occurrence of felt disease in Slovenia.
