Bridgeoporus
species of fungus
Bridgeoporus is a fungal genus in the family Polyporaceae. A monotypic genus, it contains the single polypore species Bridgeoporus nobilissimus, first described to science in 1949. Commonly known both as the noble polypore and the fuzzy Sandozi, this fungus produces large fruit bodies (or conks) that have been found to weigh up to 130 kilograms (290 lb). The upper surface of the fruit body has a fuzzy or fibrous texture that often supports the growth of algae, bryophytes, or vascular plants.
This species is found in the Pacific Northwest region of North America where it grows on large (at least 1 m diameter) specimens of noble fir (Abies procera), Pacific silver fir (Abies amabilis), or western hemlock (Tsuga heterophylla). Bridgeoporus nobilissimus causes a brown rot in its tree hosts. Genetic analysis shows that the fungus is more prevalent than fruit body distribution indicates.
Taxonomy
Bridgeoporus nobilissimus was named for William Bridge Cooke, who originally described the species as Oxyporus nobilissimus in 1949. The fungus was discovered in Clackamas County, Oregon, in 1943 by brothers Ali and Fred Sandoz. Foresters called the species Fomes fuzzii-sandozii, referring to the collectors and the fuzzy surface texture of the conk.
“Bridgeoporus” enters the record as species of fungus. Crown Archives preserves that source wording while asking what Bridgeoporus, species and fungus can confirm, complicate or overturn.
Why this record matters
“Bridgeoporus” is worth following because a concise public description often conceals a longer documentary argument. Here, Bridgeoporus, species and fungus provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 1, 2026. The linked authority identifier is Q4966554. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1949 and 1943.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
