Observation 217397: Armillaria (Fr.) Staude
When: 2015-09-28
No herbarium specimen

Notes: A few “newbies” fruiting in landscaped mulch bed beneath a live, mature Tartarian Maple. White flesh bruised very slowly (2-3 minutes) reddish brown. I was able to obtain just enough of a spore print to call it cream. KOH on cap instant reddish-orange.

Conditions are still very dry here. However, I believe the last four photos that I’ve just added are illustrative of what the mature specimens look like. Still tiny and dry, but more developed. Bruising on flesh and KOH reaction on cap are the same as earlier. Any new ideas? Thanks!

I walk my dog past that site every day. If anything

first thought when I saw them, but they were sooooo immature that I hesitated to make the call. Thanks for your expert eye! My plan is to return every day or so to see if more will emerge which I can let grow a little bigger …. big enough to ID the species. With Armillaria more should definitely be on the way. THNX again.
