I haven’t seen Singer’s nor McNabb’s work.
I think when Douglas-fir and Monterey pine were introduced into Australia and Tasmania, many fungi hitch-hiked their way at the same time.
Thanks. I noticed that also. I got KOH reaction info from McNabb, R.F.R. (1969). The Paxillaceae of New Zealand. New Zealand Journal of Botany 7(4): 349-362 http://virtualmycota.landcareresearch.co.nz/...
Perhaps it is the same as the New Zealand species. Singer thought that P. involutus was likely introduced to the southern hemisphere.
that Paxillus involutus is a European species, and not believed to be found in the U.S. For European Paxillus involutus KOH should produce a grayish reaction.
More correct is to call this Paxillus involutus complex.
The red staining with KOH is interesting, and suggests a different species as well, at least in NAMA. Apparently red KOH reaction can be a positive test for polyporic acid, at least in Hapalopilus rutilans (=Hapalopilus nidulans), and Pleurocybella porrigens. Pleurocybella porrigens was generally considered a safe edible until this data was reported. Now not so sure.
