Common Name: Ash Tree Bolete. Has grown around this tree for about 10 years. Reoccurs regularly, in fact, without fail. Has spread about 25'-30' from tree. Said to be edible by most authorities, however, I found it of poor quality and with a rather slimy texture and unpleasant taste. Thought to be mycorrhizal with ash trees but not all authorities agree. G. Kibby says that it grows in association with aphid excrement (certainly an odd associate)! 3 specimens were dried. Spore print taken. This group was taken to replace the present vouchers because of insufficient data. Very common throughout our area after mid-summer rains. Can also fruit more than once. In groups, occasionally singly. Close examination by Dr. Methven (see annotation above) combined with the 2015 DNA analysis confirmed that this specimen is Boletinellus merulioides.
