This summer has been unusually dry--we've had something like 2 inches of rain the entire summer (we average over 3 inches per month). As a mushroom guy, I've found it quite depressing. One day I woke up and the yard was a bit damp. I quickly moved from place to place to try to find live revived by the moisture. This may be Mycena corticola.

The north facing side of the shingle roof of our shed is thickly decorated with British soldier lichen.

Ants in general don't seem to be suffering in the drought, at least it seems many species are doing fine.

The edges of the thallus of this fungus suggest hammered metal, or at least they did back when such things were common, and lichen common names were up for grabs. Anyway, this is called "hammered shield lichen," Parmelia sulcata*

 photo P1070475_zpsibnolkce.jpg
Most of the visible part of it, and the part that we call Parmelia sulcata, is a fungus. The color comes from a green alga called Trebouxia, which is safely cared for within the flesh of the fungus, protected from drying out and blowing away. Or perhaps it is a prisoner, prohibited from living a free life apart from it's symbiont (there are free-living Trebouxia out there, apart from the lichen symbiosis).

The fungus depends entirely on the algae living inside it, to photosynthesize and make food for both organisms.

This time around [livejournal.com profile] mizdarkgirl suggested that we walk in the Blakely Hoar Nature Sanctuary in Brookline. We had twice as many people participating as we did January 2014. I took about a million photos, of which I've posted 20 or so:

Here again I'm testing the camera's macro ability--these are lichens and mosses growing on the surface of a storm drain. I'll have to assume here that the mosses started it, and then the lichen fungi found the moss covered metal to be close enough to earth to colonize. My field guide doesn't have a section on lichens growing on steel. These are probably Cladonia sp., but again I'd love input from the real experts.

This crustose lichen on smooth tree bark is probably something in Lecidela, Lecidea, or Porpidea.

Buying a new lichen field guide and then going out to try to identify as many as possible was amazingly humbling. I'm gonna need someone to hold my hand through this process, because it's more difficult than I thought. If you are good at this, I need your help--it might be good to know these are all on Great Blue Hill, on a wet day. Ready? Here goes:

I saw many partial fairy rings (fairy arcs?) in Florida. I saw lots of mushrooms in general, which I consider to be a huge factor in Florida's favor.

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."

At the end of the last Urban Nature Walk my friend [livejournal.com profile] dedhamoutdoors suggested we walk near Little Wigwam Pond (this is pronounced "little wiggum pond" in order to differentiate locals from carpetbaggers). A couple days later she said she found sundew plants there, and I said "sounds good! you're leading!" or words to that effect.

This first picture shows the group exploring life along the train tracks.

Wilson Mountain Reservation is a protected patch of woods on a stony hill in Dedham. The main entrance has a parking area which is almost always packed with cars full of dog owners taking their pets for a quick ramble up the path, often off-leash. My good friend [livejournal.com profile] dedhamoutdoors knows her town well, and took me to the back side of the Reservation, where we didn't see another human or canine soul. Perhaps the persistent light rain helped.

Our last stop on the vacation was the Edison and Ford Winter Estates. I was keen to see the botanical laboratories and such, not so much the big houses of two rich men I don't particularly admire. Edison was a ruthless capitalist and elephant electrocutor and Ford was a noted anti-Semite. We saw some cool stuff there though--check out the tree behind this statue of Edison.

I made sure to show my dad the Oatmeal strip about Tesla, after we got back, just so you know.

We spent some time trying to "find" Fort Myers. Gertrude Stein may have lamented that "there's no there there" about her home town of Oakland, but I've heard it more accurately applied to other places. We tried in vain to find a town center, walkable village, or cohesive sense of Fort Myers that we could understand as New Englanders. One time I set the GPS for Centennial Park, in "downtown" Fort Myers. There were tall buildings and a park, but we didn't stay long. This laughing gull gave us a funny look as we looked across to the hotels of North Fort Myers where spent the night.

The first time you see a white ibis in Florida it's shocking and magical--aren't they African animals? Didn't the ancient Egyptians mummify them by the million? Then you see a flock of 20 in a drainage ditch. Then you realize you're seeing them basically anywhere there's water. Then, if you're me, you hand-feed them cat food at the zoo.

It's always nice to closely examine the apothecia (fruiting bodies) of the blue crustose lichen on the Norway maple twig, before consigning it to a firey demise.

If you've been following my journal, you know that the night before this picture was not good. The short of it is that I tried to visit with my friend and ran into two road closures due to one serious and one fatal traffic accident. This is the glorious sunset at Ventura Beach, complete with full moon. We stayed in Ventura because we were to spend the next day at the Channel Islands National Park. These islands are across the Santa Barbara Channel from LA (as opposed to within the English Channel, where the other Channel Islands are).

Exidia recisa is the brown growth on this stick blown down by Superstorm Sandy; lichens also adorn the bark.

Exidia recisa is a brown translucent jelly-like mushroom that appears on the dead twigs of hardwood trees. It's strangely missing from many field guides, despite being completely ubiquitous, at least in our area. It's especially easy to find after a storm--the rain (or even wet snow--this is a year-round species) makes it appear, and the thin weak branches on which it grows break easily in the wind. When it dries, it shrinks to a crispy black crust, but if it gets wet again it will absorb moisture and return to its gelatinous, spore-producing form.

The view out my office window pretty much always includes juncos this time of year.


Yet another snapshot that looks like a horror movie still.


This is a stick blown down by the storm. The bluish green growth was there first, lichen soaking up sunlight while perched high in the tree. Then a wood-decay fungus invaded, eating the branch from inside, eventually producing the reddish-brown fruiting bodies fighting for space alongside the lichens. Weakened by the fungus, the branch fell to my curious hands.

Ten days ago I took Charlie for a walk in the Stony Brook Reservation, and the woodland wildflowers were starting to come up. This is starflower (Trientalis borealis). Starflower blossoms are seven-pointed stars, pollinated by native bees (not honeybees).

Yesterday I went with @WildDedham and three other hikers for a ramble in the Dedham Town Forest. Most people, including Dedhamites, have never heard of the forest, and that's kind of a nice thing. Ideally it will receive some conservation attention before it becomes well-known to the public. Since it's fairly isolated and fenced in, there's very little in the way of invasive species there. One idea is to complete the fencing to create an exclosure keeping deer out, then plant other native plants (the ones like trillium, that deer tend to graze out of existence) and preserve the place as a native forest plant sanctuary, like Garden in the Woods.

Anyway, it was a pretty amazing place, and we stayed for three hours despite some of the worst mosquito activity I've ever experienced. The mushroom hunting was the best I've ever seen.

This penultimate series of vacation snaps is mostly from in and around Forest Park, which, at "5,100 wooded acres [is] the largest, forested natural area within city limits in the United States." Some are from very close by Council Crest Park, which offers some nice views.
