In autumn, diseased leaves bearing lesions fall to the ground where they overwinter. These lesions contain perithecial initials that mature with the advent of warm temperatures and spring rains, conditions that also favor the development of new leaves on the host. Mature perithecia contain asci with ascospores that are forcibly ejected upward onto young host leaves, which they infect. These new lesions grow and produce an acervular stage that forms numerous conidia that spread the disease throughout the plant during the summer. The timing of these events is determined by weather conditions, especially rainfall. As infected leaves dehisce in autumn, they remain beneath the shrubs, where they overwinter, ready to begin the cycle again the following spring.","PeriodicalId":263988,"journal":{"name":"North American Fungi","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132400853","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}

Using spring surveys, we recovered the pathogen (as both spores and basidiomata) at 21 of 31 surveyed sites throughout the extent of the Ozarks region. Using a more intensive spore-trapping procedure, we also surveyed pure hardwood stands within the oak-pine matrix and pure hardwood forests outside the distribution of shortleaf pine. We detected some spores from pure hardwood stands that were relatively near overstory pines, but we detected no spores from pure hardwood forests at long distances (>100 m) from pines. We conducted a GIS-based analysis of pathogen presence and relative spore abundance relative to pine patch distance, pine patch size, and pine patch edge length within the surrounding landscape and determined that distance to the nearest overstory pine as well as the number of pine patches within 500 m were important predictive variables. These data indicate that Heterobasidion irregulare inoculum is likely to be detected within 100 m of overstory pines in the Missouri Ozarks region and demonstrate the ability of this pathogen to persist and spread inoculum even in a landscape with significantly reduced host plant density.","PeriodicalId":263988,"journal":{"name":"North American Fungi","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133168697","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}
