The largely subterranean nature of the mycorrhizal fungal life form impedes efforts to monitor protected fungi and evaluate effectiveness mitigations in timber harvest areas. In this study we developed tested a multiplex PCR system capable detecting 14 listed Phaeocollybia species soil. We then investigated persistence at three sites northwestern Oregon where attenuata other sporocarps had been observed prior harvest. different levels protection for fungi. One site was buffer zone next...
The polypore Bridgeoporus nobilissimus produces large perennial basidiocarps on diameter Abies stumps, snags and trees in coniferous forests of the Pacific Northwest. Despite size persistence basidiocarps, they are rarely observed, making conservation this species a concern. We determined that genetic marker for fungus could be detected DNA extracted from wood cores taken hosting basidiocarps. then tested 105 stumps did not host B. plots surrounding conks, 291 randomly located four stands...
Abstract Living fungi can be identified and monitored in their soil habitat using an array of molecular methods. However, DNA originating from dead fungal tissue may become stabilized the remain detectable for some time after cell death rendering species detections with methods difficult to interpret. Very little data exist about persistence mycelium as it decomposes within ecosystem. We placed containing heat‐killed two mycorrhizal species, Phaeocollybia scatesiae A.H. Sm. & Trappe P ....
The conservation of rare fungal sites occurring on actively managed forest lands requires efficient site monitoring methods. In this study species-specific primers for the putatively mycorrhizal Albatrellus ellisii (Russulales) were developed so that DNA extracted from soil samples at known fungus could be tested presence A. mycelium with PCR. This method was used to measure seasonal changes in levels three while utility assessed. We found maintained a constant level occupancy over seasons,...
Surveys for conks on noble fir trees (Abies procera) have suggested that the fungus Bridgeoporus nobilissimus is rare in Pacific Northwest. As a result, has been managed several decades as old-growth forest species federal lands. We undertook randomized landscape sampling approach to determine distribution of B. an 88,200 ha study area northern Oregon Cascade mountains. used molecular tools test presence fungal DNA wood cores from living and dead trees. sampled 58 plots system permanent...
Calicium sperlingiae is described as new from Oregon, U.S.A. It was collected on the bark of Pseudotsuga menziesii lands managed by Bureau Land Management, United States Department Interior. placed in based morphology (stalked apothecia with black mazaedia and brown 2-celled, ellipsoidal ascospores) molecular data. Phylogenetic relationships are inferred using ITS region. The species characterized its superficial well-developed, grayish-white, granular to leprose thallus, I– apothecia,...
