The Coral Spot was New For Me, 01-10-19

I got up a little before 7 o’clock this morning and was out the door by 7:30 am to go to the American River Bend Park with friend and fellow naturalist, Roxanne. 

Start Time: 8:00 am

43º F
End Time:
1:30 pm
End Temperature:
48º F
Weather:
Partly cloudy
Total Hours in the field (includes travel time):
6 hours
Kilometers Walked:
3

When we arrived at the park and were driving in, Roxanne spotted a very healthy looking coyote on the side of the road.  There was a woman walking along that same area, and rather than standing still so we could get photos of the coyote, she tried keeping pace with the car… and kept scaring the coyote. It ran up ahead of us and tried to hide behind a knoll, but once more the woman scared him out.  Eventually, he crossed the road in front of the car and then trotted off into the hills. I was able to get a few photos of him then, but by that time he was fairly distant from us.  I got a few shots, but could have gotten more, I think if that woman hadn’t (albeit unintentionally) interfered.

Past the biking intersection, we pulled off into the first turnout on the left and got out of the car to start scouting for fungi.  We didn’t have to go far.  Within a few feet of the car was a large stand of Honey Fungus at the base of a tree.  Around other trees we also found stands of Sulphur Tuft (a kind of poisonous mushroom)with a sulfur yellow tinge to it. [The crowded adnate gills of the Sulphur Tuft are initially sulfur yellow, becoming olive-green and progressively blackening as the spores ripen.]

Around here, we also came a fairly nice grouping of Bleeding Mycena, Mycena haematopus. I didn’t think to pull up and squeeze any of these guys, but there’s supposed to be a purple juice that comes out when the mushroom’s flesh is squeezed–especially in the base of the stem.

We followed a bachelor group of Wild Turkeys into a field on the opposite side of the road, and as we were getting photos of them, we noticed there were also several Turkey Vultures in the tree above them (and some other turkeys in the tree next to the vultures’ tree).  One of the vultures lifted its wings into the “heraldic pose” and another one did a wing-stretch for us that showed off its white underwing.  The turkeys were “strutting” and chasing one another, all a part of settling their hierarchy.

We then started look diligently for more fungi, and while we were doing that we could hear Red-Shouldered Hawks yelling at each other from the trees.  I was able to get a few shots of one of them before he flew away.  

One of the first things that caught my eye were little pinks dots covering several leafless twigs and branches (which might have been Buckeye, but I was so enamored with the spots that I wasn’t paying attention to the substrate. Naughty bad.)  I took some establishing shots with my camera, then attached the macro lens to my cellphone to get a closer look at them.  I was surprised by what I saw:  little pale pink tufts amid brighter pink (almost red) forms that looked like raspberries.  They were gorgeous!

I thought, at first, that they were some form of slime mold, but after I got home, I did more research and reached out some of the folks in the Slime Mold Identification group on Facebook, and they directed me to a fungal plant pathogen called “Coral Spot”, Nectria cinnabarina.  It usually attacks broadleaf trees (including Buckeyes in California) and is made up of a complex of four distinct species.  The pale pink blobs are the asexual condial stage of the fungal complex (borne externally to the cells that produce them), and the raspberry blobs are the fertile ‘perfect’ stage.  (So, they go from the pale blobs to the rapsberries.)  Sooooo interesting. I’d never seen or heard of anything like them, so, this was a fun find.

We also found some green mold that we hadn’t seen before.  I researched it when I got home and asked some of my naturalist graduates for help with an ID, and settled on Green Trichoderma Mold, Trichoderma viride,  a fungus and a biofungicide.  It reproduces asexually through mitosis and is the anamorph of Hypocrea rufa, its teleomorph, which is the sexual reproductive stage of the fungus and produces a typical fungal fruiting body. The taxonomy of this mold has changed a LOT, so I’m not sure if this is the most currently accepted name. A closely related species, Trichoderma reesei, is used in the creation of “stonewashed jeans”.

In that same area we found several different species of crust fungi, some nice polypores. Hair Mold, and some pretty, colorful lichens.  The Hair Mold, Phycomyces nitens , looks white when it’s fresh but if you look closer you can see its tiny yellow asexual sporangia that turn black when they go to spore. This mold is interesting because it’s also highly phototropic (its heads follow the direction of the sun as it moves across the sky. )

…Phycomyces was the second organism, after us, known to require a vitamin. …There are two main kinds of fruiting bodies, called macrophores and microphores, which differ in size, development and behavior. The spores disperse efficiently when they adhere to passing animals or are eaten by them…”

When we were done in that field, we crossed back toward where the car was park and found more Honey Fungus and polypores.

Then we drove further into the park toward the camping area, and I had Roxanne stop the car in the road when I spotted a huge Common Ink Cap Mushroom, Coprinopsis atramentaria, and some of its “children”.  It was the biggest specimen of that mushroom I’d ever seen.  Very photo worthy.

In that same field, I was also surprised to see lots and lots of Palomino Cup Fungus, Peziza repanda.  I’d never seen them in that particular field before, so it was fun to see them there.  Each one is a different shape depending on how it grows up through the grass, so I got dozens of photos of them.

Then we continued on to the camping area, and found some nice-looking Barometer Earthstars, Astraeus hygrometricus.  We also got views of the American River and could see a few bird species in and around the water including some Common Mergansers and Goldeneye ducks, a Double-Crested Cormorant, and a little Spotted Sandpiper(without its breeding spots).

We walked for almost five hours (!) and then headed home.
