On saturated sticks in creek channel
Parasite on uredinia of a Puccinia sp. on a Carex sp. leaf.
Abundant on urediniospores of Puccinia menthae on Cunila origanoides. Spores 14-16 x 4-5um
Understory shrub in a lodgepole pine stand at Grass Lake, El Dorado County, California, elev. 7720 feet.
On a branch of Amelanchier sp. in a lodgepole pine stand at Grass Lake, El Dorado County, California, elev. 7720 feet.
In sphagnum in an acid bog
Forgot to collect. Thought it was miyabeanum due to small size of plants. But branch leaves look quite hooded/ almost squarrose
On Osmundastrum cinnamomeum. One of the harder rusts to photograph as I can never find very many spores. Urediniospores present. White, complete with an all white Mycodiplosis larvae, I guess that confirms their normal orange red color comes eating colored spores.
Urediniospores fusiform and colorless (I dyed them red in the photo. 47-55 x 31-15 um. Ref: Arthur’s Manual of Rusts of the United States. The description says the Urediniospores are ciliated on the two ridges, which is what I imagine the ruffled sides are?
Guess this keys out to fuscum
Loose hummock in shade, peatland on edge of pond, did not see other fuscum
Salt Point State Park, near Central Trail. Mixed confier/hardwood coastal forest; Sequoia sempervirens, Abies grandis, Pseudotsuga menziesii, Notholithocarpus densiflorus, Pinus muricata, Arbutus menziesii
Growing on a well rotted and de-barked Notholithocarpus densiflorus
Tiny, pea sized orange pleurotoid fungus. Laterally attached stipe with distantly spaced, subdecurrent lamellae. Pileus striate, so thin you can almost see through it. Reduced stipe covered in tiny white hairs.
No noticeable smell, taste mild

Growing in moist Sphagnum moss near Salix and Vaccinium uliginosum
Pileus bright red, dome shaped, texture of fine scales. Lamellae white to cream, subdustant, waxy, broadly attached to sub-decurrent. Stipe waxy, bright yellow, equal
Smell and taste indistinct

On Populus tremuloides
Hypophyllous on Prunus sp., I think P. serotina. Cell wall of urediniospores strongly thickened apically. Measuring 34-47 x 17-19 um. Teliospores not found. Occasionally a bit longer than spore measurements found in this key: https://www.researchgate.net/profile/Markus-Scholler/publication/262696820_Tranzschelia_in_the_Americas_revisited_Two_new_species_and_notes_on_the_Tranzschelia_thalictri_complex/links/0046353c6a4239cc04000000/Tranzschelia-in-the-Americas-revisited-Two-new-species-and-notes-on-the-Tranzschelia-thalictri-complex.pdf?origin=publication_detail&_tp=eyJjb250ZXh0Ijp7ImZpcnN0UGFnZSI6InB1YmxpY2F0aW9uIiwicGFnZSI6InB1YmxpY2F0aW9uRG93bmxvYWQiLCJwcmV2aW91c1BhZ2UiOiJwdWJsaWNhdGlvbiJ9fQ
CA24-00848
Super abundant in the area. Redwood, fir, and alder growing in the area. Noticed alongside the trail. Lots of them in the whole area. Pine trees nearby and redwood.
Justin found the population and I helped him gather additional specimens for a better collection: https://www.inaturalist.org/observations/233862815

Growing on decorticated chunk of wood with Fraxinus pennsylvanica. Pinus nearby.
A Hymenoscyphus perhaps?
Tiny yellowish, stipitate fungi,

KOH = red

I have no (zero) idea what I’m looking at. Pretty sure it wasn’t the tree’s fruiting body, but that’s my limit of knowledge.
Craterellus seen commonly in peatlands with a shaggy, tomentose cap
This is the first Pinus monophylla I saw infected, but many many more up canyon from here were infected
