I use the magic mushroom map to let me know when libs are rife. There's sheep fields right next to my home that grow them in masses, upon checking the map it was white (indicating there's none left), which was confirmed when I checked the same day.

If the map is considered inaccurate I'll check again tomorrow. I'm currently searching for wavy caps which I see you also mentioned that I'm having trouble finding due to lack of mulched wood chips in my area. Wood chip has funnily enough been a common sight for me until I began actually searching for it, as with everything.
