In the Rogers family, as well as the Silver Lake community (and lots of others) you commemorate an experience by writing or drawing on this type of fungus, which grows on dead or dying trees. Some people do very intricate designs or pictures. My friend Linda has some beautiful pictures on her fungi. I'm very poor at this and have a collection in my house that's very similar to this one. Sometimes when I look them all over I can remember the walk, the evening, the afternoon when I found them, other times I have no real recollection of the time. Maybe, because I took so many pictures this time I'll remember the evening's stroll.
