Wanted: Phaeolus schweinitzii

Phaeolus schweinitzii (Dyer’s polypore) is (as mentioned by our September speaker, Alissa Allen) often collected as a choice dye mushroom. It is also a tree pathogen, causing root rot and butt rot in conifers [1][2].

So if you are not collecting P. schweinitzii for dyes, please consider this request for specimens from plant pathologist Andrew Lloyd:

“I am currently doing research related to Phaeolus schweinitzii in the United States, and would love to accept fresh samples of P. schweinitzii from the U.S. to establish cultures and work on the taxonomy of this fungus. Please consider your submission. Than you in advance, and please don’t hesitate to email with questions or with shipping and handling for your specimen.”
