Consulted experts for ID as I an unfamiliar with most amanitas
It was found along the upper section of the East Trail descending towards Russian Gulch Creek; probably a five-minute walk from the north boundary trail connection. Redwood habitat but fairly dry currently. I've tried to guesstimate the coordinates here: 39.334089, -123.760694. The iphone coordinates place it too near the creek I think.
There were three growths present on the uphill-side of the trail. Only one was growing with the wooly chanterelle.
Substrate: mud at the bottom of a granite step, right in the middle of the trail. Same specimens as https://www.inaturalist.org/observations/118996208
This name has been updated. I IDed it using the old name Neohygrophorus angelesianus in "The Essential Guide to Rocky Mountain Mushrooms by Habitat", esp the KOH test.
A patch about 2 m square of about a dozen clumps of 2 - 4 individuals each, 2 to 4 cm tall. On the hillside east of cabin number 14 at Oconee State Park, SC. Growing on the ground in leaf litter under mostly hardwoods.
Mike Hopping suggested this species, ID based on Coker's description (see https://www.biodiversitylibrary.org/page/4597353#page/89/mode/1up)
and Mycoportal has a page on it including several collections from the Highlands area." https://mycoportal.org/portal/taxa/index.php?tid=142045&taxauthid=1&clid=0
"Mushroom Observer shows one observation, collected by Jacob Kalichman and sequenced at UT. That mushroom doesn't much resemble the original description."
