Kubiak","doi":"10.5586/am/176036","DOIUrl":"https://doi.org/10.5586/am/176036","url":null,"abstract":"The research aimed to study the extent of fungicolous fungi prevalence on the thallus of fungi parasitic to the plants of the urban environment and to assess the species diversity of these microorganisms, with particular attention paid to the phenomenon of hyperparasitism. The research material consisted of herbaceous plants, trees, and shrubs showing signs of infestation by fungi, planted as park plants, along communication arteries, for hedges or ornamental plants, collected in larger cities of north-eastern Poland. Macroscopic and microscopic analysis revealed the presence of 12 different species of fungicolous fungi. The greatest diversity was found on the parasite of Alcea rosea, i.e., Puccinia malvaceraum, on which four fungal species were recorded. Four species of hyperparasites were identified: Ampelomyces quisqualis on the thallus of 19 Erysiphales species,Cladosporium uredinicola on the thallus of 5 species of the Pucciniales order, Clonostachys epichloë on Epichloë typhina, and Sphaerellopsis filum on the thallus of 11 representatives of Pucciniales. The study was also the first to record the presence of superparasites: Ampelomyces quisqualis on four Erysiphales species and Sphaerellopsis filum on three Pucciniales species. It is difficult to determine the relationships established by the other identified fungicolous fungi due to the lack of literature data. Nevertheless, the study demonstrated the presence of, among others, Stemphylium sarciniforme structures inside Erysiphe palczewskii appendages and the absence of ascospores inside the fruiting bodies indicative of the invasive nature of this relationship. However, confirmation of these findings requires further detailed microscopic and molecular analyses.","PeriodicalId":37880,"journal":{"name":"Acta Mycologica","volume":"65 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139146755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Szymczyk, M. Kukwa","doi":"10.5586/am/175356","DOIUrl":"https://doi.org/10.5586/am/175356","url":null,"abstract":"The first records of Parmelia ernstiae from Madeira, as well as the new localities of P. encryptata from Poland and P. sulcata from Chile, are presented. All records are confirmed by molecular data, BLAST search, and haplotype network analysis of the nucITS rDNA sequences. The discussion on the morphology and secondary chemistry of all three species is provided with notes on their distribution and similar taxa. Parmelia encryptata is a rarely reported cryptic species that is morphologically indistinguishable from P. sulcata, and its identification requires molecular data. New localities of P. encryptata from northern Poland suggest that the taxon may be widespread in the country and not confined to large forests but also present in open areas on free-standing trees. Moreover, a new nucITS rDNA haplotype of the species is reported. Parmelia ernstiae is a near-cryptic species, morphologically and chemically very similar to P. saxatilis and P. serrana. Two specimens of the species from Madeira have sublinear lobes with marginal and laminal isidia, unlike most specimens of P. ernstiae, having short, broad lobes with laminal isidia, and thus are morphologically closer to P. saxatilis in lobe shape and to P. serrana in placement of isidia. However, the BLAST search and haplotype analysis of nucITS rDNA sequences placed these specimens in P. ernstiae. Parmelia sulcata, a common species in the Northern Hemisphere, is rare elsewhere, and only two records confirmed by molecular data were known from South America. The nucITS rDNA haplotype of two new and two previous records of the species represent the most common haplotype of the species known from the Northern Hemisphere.","PeriodicalId":37880,"journal":{"name":"Acta Mycologica","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139149392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Baturo-Cieśniewska, Katarzyna Patejuk, Agata Kaczmarek-Pieńczewska, Marta Jurga-Zotow","doi":"10.5586/am/174570","DOIUrl":"https://doi.org/10.5586/am/174570","url":null,"abstract":"Small balsam (Impatiens parviflora DC.), an invasive plant native to central Asia, is currently one of the most extensive invasive plants in Central Europe, including Poland. Its expansion may affect populations of native species, such as touch-me-not balsam (Impatiens noli-tangere). It is particularly dangerous in legally protected areas, where the possibilities of eradicating it are very limited. There is some hope for stopping its expansion by using pathogens as a biological weapon. In this case, useful may be host-specific rust fungus Puccinia komarovii var. komarovii. \u0000Our three-year observations of I. parviflora infection severity by P. komarovii var. komarovii carried out in Poland in Drawa National Park (DNP) and Wigry National Park (WNP) showed the higher incidence of rust on leaves in DNP, where the median blade infestation for two years was 51% of leaf coverage. In contrast, for three years in WNP, the median blade infestation amounted to only 25%. The most severe symptoms occurred during the summer months. However the percentage of leaf coverage by pathogen exhibited fluctuations depending on the year, implying an influence of environmental conditions that stabilized the infection each season. \u0000Molecular analyses, in addition to confirming the infection of the tested plants by P. komarovii var. komarovii, enabled the characterization of its population based on comparative analysis of ITS and LSU sequences. Clear differences were found between the studied isolates and P. komarovii from I. glanduliferae and I. brachycentra. \u0000There was no diversity among our isolates, but they differed from the sequences of Polish isolates originating from I. parviflora available in GenBank, which indicates some diversity of rust in a relatively small area. It probably results from sexual reproduction and may enable rapid adaptation of the pathogen to the region or host plant, or it may indicate certain “entry points” to Poland, where the isolates arrived from their native place of occurrence.","PeriodicalId":37880,"journal":{"name":"Acta Mycologica","volume":"46 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138974805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The establishment of mycorrhizae is considered a factor influencing invasion success. This study aimed to compare the frequency of mycorrhizae in the roots of the foreign and invasive black cherry and the native common cherry, which are related. The frequency of ectomycorrhizae was assumed to be higher in common cherry (<i>Prunus padus</i>) than in black cherry (<i>Prunus serotina</i>). Thirty 2–3-year-old trees (15 <i>P. serotina</i> and 15 <i>P. padus</i>) were collected from stands where they grew next to each other. Samples were collected in June 2022 from the Forest Experimental Station of Siemianice, Złotówek, and Mrowino. The presence of mycorrhizal fungi was assessed. Morphotypes of ectomycorrhizae were determined with a stereoscopic microscope. The average mycorrhizal frequency was calculated. The roots were scanned and determined with the WinRhizo image analysis system. The length, surface area, diameter, volume, and number of root tips were determined. Statistical analysis of the obtained results was performed with Statistica v.13. The laboratory analyses indicated the dominance of morphotype 3 in all the examined roots of common cherry and black cherry. The highest proportion of type 3 mycorrhizae was found in common cherry at each location. This study showed that black cherry can form ectomycorrhizal associations, which probably positively influenced the success of its invasion.","PeriodicalId":37880,"journal":{"name":"Acta Mycologica","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135826980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
