Large fruiting in Atlantic white cedar swamp. Two densely wooded locations about an eight of a mile apart. Many dozen individuals in all stages of growth. Very few macro fungi present besides this species.
The first ID suggestion posted to facebook Ascomycetes of NA was Sowerbyella rhenana, a good starting point, but likely not the correct ID, as the mature spores dropped by my fruit bodies have dimensions 9-13 x 4-5.5(6.5) that era significantly different from what is reported for S. rhenana, 18-23(26.3) x 9-13.
I posted this to Asco France and got soem good help from those folks. A key provided led me to three names of species that are similar: S. radiculata var. kewensis, S. polarpustulata, S. brevispora. The latter seems like the best match, although the color of the hymenium is described as darker than for my observation. I used the following chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://www.funga.fi/Karstenia/Karstenia%2024-1%201984-4.pdf .
Material has been dehydrated and is available for study.

On Dryopteris intermedia; observation for host plant: https://www.inaturalist.org/observations/220881135
Found in the same location as the June 17, 2023 observation. On the south side of the Allegheny River, under the Kinzua Dam. In a slow moving area protected from the fast water by the large rocks placed along the shore to stop erosion. The mushroom was growing out of the underside of a stick approximately one foot long and an inch thick at the thick end. The water is about a foot deep, and the stick is suspended horizontally about six inches under the surface by rocks at both ends. This is at the outflow of a culvert. The other nearby location is at another culvert.
On the cut end of a large downed tulip poplar.
Spores amyloid; 5-7 x 2.5-3.5.
Largest cap do nit exceed 2 cm in diameter.
Found not long after a snow melt. Possibly M. overholtsii, a species once believed to fruit mainly in western NA coniferous forests. I think this is the same species as what MycoQuebec used to call "Mycena aprilis."
Probably a species in the G. ancilis group. I left a couple fruit bodies in situ to hopefully mature. These types of fungi mature very slowly. I'm hoping to eventually get a spore drop.
Site 3, 14 Sarcosoma globosum spotted today. Not much change from last week, all still fairly fresh.
submerged in spring run, but would be above water much of the year.
Vibrissea truncorum?
apparently a complex, two species complexes actually: Rosanne Healy, FB group, Ascomycetes of NA decaying hardwood, same as Psathyrella sp.
In/near sphagnum.
Taste acrid.
Cuticle peels 0.6R-0.75R.
Spores 7-9 x 6.5-7.5 with warts mostly under 1.0 micron and mainly isolated but with some scattered connections.
Very good match for R. anisata via Kibby-Fatto key.
In sphagnum.
Crushed flesh odor of radish.
Spores amyloid, 10-13 x 6-8.
Except for odor --which C du Q describes as alkaline-- this is a very good match for M. megaspora.

Endemic to the Appalachians and one of the only aquatic lichens, this species is uncommon and is indicative of high water quality. It looks like it belongs in a tidal pool. A Pennsylvania 'Watchlist' species.
Under birch, tulip poplar, and hemlock. Found in multiple locations along this trail, growing in small groups. Very pale /almost pink compared to the other Clavulinopsis. More of an orange color at the base.
Growing under oak, birch, and hemlock. Growing in large groups. Pale orange, almost peach in color and more of an orange at the base of the stipe.
Mycowalt told a neat story about this mushroom at the Ohio gathering a few weekends ago. Supposedly the ash bolete grows on honeydew from aphids that suck sap from the roots of ash trees.
Michael Kuo tells a similar story:
http://www.mushroomexpert.com/gyrodon_merulioides.html
I noticed a few things the other day that makes me suspicious of the accuracy of this story.
I did not find any aphids around these mushrooms, even though I examined quite a few of them. I only found the little black blobs shown here. Kuo says the blobs are sclerotia that surround the aphids, but if the aphids are completely encapsulated in sclerotia, then how can they bite into the roots? Furthermore, none of the black blobs I observed appeared to be attached to roots. On top of all that, some of these mushrooms were growing from rotted wood, several inches above the ground. Above-ground rotting wood is not the kind of place were one would expect to find aphid infested tree roots; I found neither aphids nor roots in the rotting wood.
I wonder if something more complex than the received story is going on here.
Found on an Atlantic White Cedar tree. Would like to know what else it could be if not this species.
I'm calling this remarkable fungus Sarcodontia amplissima. I noticed a resemblance to Radulomyces copelandii, but I knew it couldn't be that because of the vivid color—yellow with a slight greenish cast and areas of reddening. It had an intense, unpleasant odor that was apparent from a distance, but I wasn't sure it was coming from the fungus initially. When I smelled it at close range, I ascertained that the odor, which brought to mind wet plywood and sour towels, was indeed coming from the fungus—but at close range there was an additional, more pleasant component that I couldn't put a name to. Descriptions I have found mention fruitiness and unpleasantness.
I've been trying to unravel the taxonomy of this species—a number of names have been bouncing around with some conflicting ideas about synonymy. This 2021 research seems to have sorted the mess pretty well: https://www.fs.usda.gov/nrs/pubs/jrnl/2021/nrs_2021_nakasone_001.pdf
According to the findings of this research, the European species which closely resembles my find should be called Sarcodontia setosa. The name Sarcodontia crocea has often been used for finds resembling this, but that is apparently "based on an erroneous concept of Sistotrema croceum." The latest name for that species is Noblesia crocea—but it is apparently quite different from Sarcodontia amplissima and S. setosa.
The substrate was largely decorticated, and I was uncertain of its identity—but after researching the fungus, Malus (apple) seems plausible based on the shape of the limbs and the residual bark.
Also called Toothed Crust fungus. Radiating crust fungus with toothlike pores. Grows on dead wood. Edges are whitish, and become dirty yellowish toward the center.
Growing underwater in the river at a depth of about a third of a meter. Location was almost the same as a sighting from the previous week

There was one mushroom growing on one end of a short stick. The mushroom and the stick were entirely under water. This was just downstream from Kinzua Dam, in about 6 inches of water, and about 18 inches from the shore. Among rocks that protect it from the fastest water.
On 10-June-2023, A second mushroom was growing on the opposite end of the stick, also entirely under water.
This tooth fungus was growing on a fallen maple tree. The color was actually more cream than yellow.

Anchor Crossing, Bucks Co, PA.
Found on a standing dead Malus.
Noted a sweet, fruity smell.
