A field guide to the fungi of central Massachusetts — and a record of the weather that produced them.
Every mushroom here was photographed where it stood, then written up with what can honestly be said about it — and what could not be, without a spore print or a look at the stipe base. 54 of 111 entries are still unidentified, and they say so.
Each walk carries the observed rainfall and humidity from the days leading up to it. That turns out to be the most useful thing in the guide: a soaking followed by warm, rain-free days is what produces a flush, and the record now covers enough walks to start seeing it.
