Soils suitable for Oregon Truffles

Oregon truffle soils

A new paper just published on Mycorrhiza, where authors make an screening of all the fungal species living on Douglas-fir (Pseudotsuga menziesii) producing Oregon truffles. This is done using pyrosequencing techniques.

A total of five Tuber species were detected. T. oregonense was the most abundant, followed by T. gibbosum and Wilcoxina mikolae. They found that Tuber species can be dominant ectomycorrhizal symbionts of Douglas-fir.

    Your entry prompted me to purchase the Mycorrhiza study, very interesting and thank you. A question, where did the blue/red map on your blog come from?
