“…Both the Maximum Likelihood and Bayesian analyses placed G. pygmaeus with members of Gymnopus sect. Impudicae in a strongly supported clade (100/1.00), and equivalent to the clade /impudicae ( Coimbra et al 2015 ). Despite of its negligible smell and pileipellis as a cutis made of smooth to poorly diverticulate hyphae, in contrast to the diagnostic features of that section ( Antonín & Noordeloos 2010 ), the phylogenetic data suggest the placement of G. pygmaeus within Gymnopus sect.…”

“…Other species in the section that are characterised by having small basidiomata are G. bisporiger and G. montagnei ( Antonín & Noordeloos 2010 , Coimbra et al 2015 ). The former, known only to the Netherlands, differs from G. pygmaeus by having larger basidiospores (7–8.5 × 4–5 μm), mostly 2-spored basidia, the pileipellis a thick ixocutis with nodulose hyphae and absence of clamp-connections ( Antonín & Noordeloos 2010 ).…”

Gymnopus montagnei is widely distributed in the Neotropics and differs from G. pygmaeus mainly by its conical to goblet-like basidiomata with a hard consistency, hymenium lacking true lamellae, inconspicuous basidia and a pileipellis resembling a trichoderm, made of strongly diverticulate and coralloid terminal cells ( Coimbra et al 2015 ).…”

“…The genus Gymnopus , includes approximately 350 species, each with a small brown fruiting body, tough stipe and white spore print (Coimbra et al, 2015; Dutta et al, 2015). Species in this genus are also often compared with members of closely related genera, especially Collybia (Vinet & Zhedanov, 2011), due to the similar morphological characteristics of many genera in the family Marasmiaceae/Omphalotaceae (Putra, 2020).…”

Using a systematic approach to synthesize existing knowledge on Gymnopus fusipes (syn. Collybia fusipes), the cause of Collybia root rot

Gymnopus fusipes (syn. Collybia fusipes; syn. Agaricus fusipes) is an agaricomycete fungus known to cause root rot on a number of economically important tree species, including oak, where it has been linked to the development of chronic oak decline.Due to lack of correlation between above-ground decline symptoms and G. fusipes infection, its presence can often go undiagnosed until mortality. Although G. fusipes was first described over 200 years ago, there is still a paucity of information on the biology and ecology of this species, which represents a barrier to understanding its impacts on tree health. The aim of this review was to synthesize existing knowledge on the biology, ecology, host range and host interactions of G. fusipes. Using a systematic search, five online databases were used to obtain published literature resulting from the search terms 'Gymnopus fusipes', 'Collybia fusipes' and 'Agaricus fusipes'.After a strict filtering process, the papers were examined for data pertaining to the biochemistry, distribution, ecology, genomic information, host range, infection biology, morphology and phylogeny of the species. The results reveal that there is a large amount of ambiguous and sometimes spurious citation of G. fusipes in the literature.However, it can be confirmed that G. fusipes is a facultative saproparasite, found in several countries, mainly in Europe, and is associated with several socioeconomically important host species, including oak, chestnut, and fir. Gymnopus fusipes has repeatedly been investigated with regard to oak decline in Europe, where it is believed to play a crucial role in the early stage of decline development. Key knowledge gaps highlighted in this review include a lack of information on the basic biology of the species, including its life cycle, which is crucial to fully understanding G. fusipes infection and epidemiology. Further work is needed to assess G. fusipes distribution, phylogeny and host range through molecular identification. There is also a need to characterize the pathogen-host interaction at a molecular level, with identification of active genes and therefore the mechanisms of infection. A combination of culture-based and molecular techniques should be utilized in order to close these key knowledge gaps.

“…PCR reactions (25 μL) contained 8 μL 2 × EasyTaq ® PCR SuperMix (TransGen Biotech Co., Ltd., Beijing, China), 1 μL 10 μM primer L, 1 μL 10 μM primer R, 3 μL DNA solution, and 12 μL dd H 2 O (Hu et al, 2021a , 2022 ). The reaction programs were as follows: for ITS, initial denaturation at 94°C for 4 min, followed by 30 cycles at 94°C for 1 min, 54°C for 1 min and 72°C for 1 min, and a final extension of 72°C for 10 min (Coimbra et al, 2015 ); for nLSU, initial denaturation at 95°C for 3 min, followed by 30 cycles at 94°C for 30 s, 47°C for 45 s, and 72°C for 90 s, and a final extension of 72°C for 10 min (Ryoo et al, 2016 ; Hu et al, 2021b ). The PCR products were visualized via UV light after electrophoresis on 1% agarose gels stained with ethidium bromide and purified using the Genview High-Efficiency Agarose Gels DNA Purification Kit (Gen-View Scientific Inc., Galveston, TX, USA).…”

Gymnopus sect. Impudicae is a poorly studied group around the world. However, it is well known for its pungent smell—a total of five species from China belonging to sect. Impudicae were recorded, and included four species new to science—G. epiphyllus, G. cystidiosus, G. subdensilamellatus, and G. subpolyphyllus—which were delimited and proposed based on morphological and molecular evidences, and one new record from Henan, Jiangxi, and Gansu Province, China—G. densilamellatus. Detailed descriptions and illustrations were presented as well as comparisons to similar species. Phylogenetic analysis inferred from the ITS and nLSU dataset supported the Gymnopus as a monophyletic genus which was defined by Oliveira et al., and the novel species grouped as separate lineages within it. A Key to the reported species of Gymnopus sect. Impudicae is also provided.
