Arborists with a mycological bent often know Grifola fron-dosa because it is common around oaks in the late summer and fall, is good to eat and has a well-known anti-cancer medical profile. It is often referred to under the name "Maitake." The fungusis found mostly east of the Rocky Mountains, getting its common name of "hen of the woods" from the clustered appearance of the fronds that may resemble the back end of a hen chicken. But should arborists worryabout G. frondosa fruiting near or on a client's oak year after year (Photo 1)?
