I already posted this little group of mushrooms, deeming them to belong to an "unknown Amanita sp." but after some research--most importantly, looking at my own photos from the same area in previous years--I'm prepared to go out on a limb. These appear to the Amanita species complex called "the blusher." At the moment our Northeast species goes by the same scientific name as the European one: A. rubescens* but as mycology progresses, we are likely to have our own name for our own mushroom.

This mushroom has all the classic field markings of the Amanita group: a warty cap, a partial veil that becomes a skirt-like ring, white spores, gills that don't touch the stem, and a swelling at the sub-soil level of the stem. Additionally, the blusher tends toward reddish hues, becoming more so when cut or bruised. Field guides say that the European variety is edible, once the toxins are ruined by cooking. This group contains many poisonous mushrooms, including the mushrooms that have killed more people than any other, which contain poisons that are not deactivated by cooking. Prudent sources advise: just don't.

This rainy day, and this mushroom I found on this rainy day, marked the end of my personal drought of interesting mushrooms. Big, bold, orange, and complete with all the field markings of an Amanita*: Warts on the cap, a ring on the stem, a swelling at the base. Or if you want the proper terms, patchy universal veil remnants on the pileus, partial veil remnant in the form of an annulus on the stipe, and a clublike volva. The yellow warts and stem helped me identify it as A. flavoconia** called "yellow patches" in many field guides. The feature that earns it that name has been washed off by the rain in these other specimens--good thing there were a ton of these around in various stages of development. These mushrooms are the reproductive structure of a fungus that weaves the roots of the various trees together as a massive interconnected symbiotic superorganism. It is noted for being especially likely to form mycorhizzae with hemlock, a tree species that in our area is under serious stress from an invasive insect. Astonishingly, considering how large and common and colorful this species is, there is no definitive note on whether it is edible or not. All the guides advise caution, since this genus includes the species of mushrooms that have killed more people than any other.

I found a mushroom during the zoo mushroom class, it seemed to be a small Amanita--the whitish gills looked mostly free, it had ball-like base, a ring on the stem, it was growing from the ground not from wood. I cut the cap off and put it on a piece of paper and covered it with a small bowl. Then I forgot about it over the weekend.

On Monday I found it--the cap had mostly dried up, but had left this deposit of white spores (Amanitas have white spores, but so do many kinds of mushrooms). The brown discoloration is from the moisture of the mushroom causing a secondary rot of some kind--mold or bacterial. For some reason photos taken with my phone are super magenta, so I have to adjust them way toward green for them to look right.

This Amanita mushroom is most likely A. rubescens, called "the blusher" for the pink tones that overcome it as it ages.

In April Urban Nature Walk went to Ponkapoag Pond. Some folks stayed for four or five hours, finally making it to the bog. Alas, I had to leave after 2 hours. Friends of mine (locals I call the "nature friends") found out I'd never been to the bog and were horrified. Finally enough things came together and I planned for the July walk to approach Ponkapoag from the opposite side so we would get to the bog quicker. Even before we got to the bog, it was a very different walk than the one we took in April. For one thing: mushrooms!

These little teeny guys were right by the trailhead (which is right off of rt 93). They look very similar to mushrooms we've seen at Cutler Park--we haven't identified them to species, but Alexis named them "Spaghettio mushrooms."

Summer is awesome because even if you are working hard at your job at the zoo (I promise) you can find new and interesting living things everywhere you look! Here's yet another Amanita mushroom!
