I agree.  Put the loam in the wood nodes since the only other things besides wood you get there are the uncommon flowers and the rare wood.

 

Something else to think about is make the fungi regular resources usable to determine the color of light or very light armor (can we all say dyes).  This would increase the need for the fungi resources and give tailors a way to color the armor they make creating a multitude of "different" armors (could have them affect stats too).
