Several rust species infect Caltha species, but only Puccinia areolata, Puccinia treleasiana , and Puccinia gemella have been reported in the Pacific Northwest. Observations were made on rust incidence and severity on Caltha spp. in July through September between 2001 and 2013 in subalpine regions of Colorado, Idaho, Montana, Utah, Washington and Wyoming. Leaves, petioles and flower stalks with rust pustules were examined and the host species identified using morphological characteristics. Plants collected in ID, WA, and MT were identified as Caltha leptosepala ssp. howelli (syn Caltha biflora ) and plants in WY, CO, and UT were identified as Caltha leptosepala ssp. leptosepala . Foci of infection were typically solitary leaves, individual plants or small clusters of infected plants although a 90% incidence of infected rust plants was observed in a 10 m diameter area with no visually distinct foci in WA in 2013. Puccinia areolata was the only rust observed in Washington, Puccinia gemella was observed in Idaho, and Puccinia treleasiana was observed in Montana and Wyoming. Collections made possible direct comparisons among the three rust species.","PeriodicalId":263988,"journal":{"name":"North American Fungi","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124424703","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}

Despite the size and persistence of the basidiocarps, they are rarely observed, making the conservation of this species a concern. We determined that a genetic marker for this fungus could be detected in DNA extracted from wood cores taken from trees hosting basidiocarps. We then tested 105 trees and stumps that did not host B. nobilissimus basidiocarps in plots surrounding B. nobilissimus conks, and 291 trees and stumps in randomly located plots in four stands that contained at least one B. nobilissimus basidiocarp. We found that trees of all sizes throughout all of the stands hosted B. nobilissimus . The proportion of Abies trees (live and dead) colonized by B. nobilissimus in these stands ranged from .06 ± .04 in a recently thinned stand to .39 ± .08 in an old growth stand. The spatial density of B. nobilissimus colonized trees ranged from 25 ± 13 to 61 ± 12 trees/ ha. The spatial density was highest in the old growth stand, but intermediate in the recently thinned stand. In a separate study we detected B. nobilissimus DNA in three conifer species that were not known to host this species: Pseudotsuga menziesii , Tsuga heterophylla , and Thuja plicata . Our results indicate that the survival strategy of this fungus is to produce and maintain a mycelial presence in its hosts while infrequently producing a long-lasting basidiocarp. The detection of B. nobilissimus , and other fungi adopting this reproductive strategy, is difficult using visual observation, but achievable using methods based on DNA detection of mycelia in hosts.","PeriodicalId":263988,"journal":{"name":"North American Fungi","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121774293","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}
