These are the first boletes that appear in my yard each summer. The bad news is that they are always immediately parasitized by a mold that I have tentatively identified as Hypomyces chrysospermus.
The mold starts on the bottom on the pore surface around the stalk, then spreads until the mushroom is completely disfigured. And it is poisonous.
The good news is that the delectable boletes are on the way. And the parasitic mold doesn’t affect the other ones.
I also have seen small puffballs in the yard the past week or so. David Fischer, in his book Edible Wild Mushrooms of North America, says that many of the small puffballs are edible. But the ones with tough rinds (that you can’t cut easily with your fingernail) are poisonous. These little puffballs have a leathery, tough rind, so even though they are perfectly white in the middle, I leave them alone.
[Edited: I have since identified these puffballs as Lycoperdon Marginatum.]
If you have the slightest interest in learning about wild edible mushrooms, I would strongly recommend that you get Fischer’s book. I have a small library of mushroom books, but Dave Fischer’s is the only one that gives a set of identification keys that completely rule out poisonous lookalikes — IF you conscientiously follow them.
I am really excited that the bolete season is finally underway. I hope to have a lot of mushroom photos to share with you before too long!
