A helpful mycologist gave me a handful of Cortinarius (something like semisanguinous-- you can tell I'm not a botanist, which is also why I don't eat anything I gather). I got peach color on alum-treated wool, and a bit more lavender on unmordanted wool. Second and third dye baths in same pot liquor gave golden beige, not at all "blah". So I'm very happy and need to find some of these in my own wood-lot. Looking for other knitter-dyers with comments on this or other fungi colors.
