Deconica cf. inquilina under 365 nm light
Seen in Mendocino County, CA yesterday.
One of the best use cases for UV fluorescence is quickly being able to differentiate mushrooms in the Genus Deconica from other similar looking dark spored fungi that hang out in the same environment #fungi #mushroom

Gliophorus cf. psittacinus
Based upon current ITS sequences on the west coast of North America we have at least 3 genetically distinct mushrooms going as the "Parrot Mushroom," called so due to its dizzying array of colors from chartreuse to orange to pink. #mushrooms #fungi #fungifriends #mendocino

Chanterelles are still up in Humboldt County and the extra long growing season is resulting in some of the biggest C. formosus I’ve ever encountered #mushrooms #fungi #fungifriends #chanterelles

Found yesterday in the Oakland Hills in half buried and well decayed Coyote Brush (Baccharis pilularis). This small and widely distributed Sclerotiniacee is easy to miss as they are rarely larger than 0.5 cm #fungi #fungifriends #mushroom #oaklandmushrooms #EBRP

Cortinarius vanduzerensis
The most impressive slime veil of any mushroom that I am familiar with in California. Why invest so much energy in a slimy cap? Could be the ability to trap arthropods attempting to eat the gills or just a way to deal with rain.

Excited to see Dendrocollybia racemosa in the Oakland Hills this week. This mushroom hedges it’s reproductive bet by making sexual spores in the gills of the cap and asexual spores on the branches on the stem. It parasitizes Russulaceae fungi and is having a very good year #mushrooms #Oakland #fungi

Happened to catch a brown rat this morning while trying to leave town. It was surprisingly UV fluorescent under 365 nm light. if you encounter UV fluorescent organisms please consider adding them to this project on iNat that I curate: www.inaturalist.org/projects/uv-... #UVfluorescence #rats #UVF

Did anyone else see a weird arc above the Aurora last night? Trying to rule out if being an artifact from my phone. It seemed most present at 8:39 PST and then faded as the light show got more intense. If you saw it, please make an observation of it on www.aurorasaurus.org #aurora #northernlights

Lucked out and saw the bay areas rain beetle, Pleocoma behrensi, during that good rain we just had. These beetles live under ground for up to 14 years, adult males emerge for a few days to find mates and then die. None of the adults have mouths. #Pleocoma #RainBeetles #beetles #SFBAY #oakland

The Sierra Nevada in California just got a flirt of snow on Friday, enough cold to really set off fall colors and the last push of high high elevations mushrooms. Made a few collections of Cortinarius that I can’t identify which always feels good. #sierranevada #fallcolors #fall

I love UV fluorescence and Craig does this on a very high level with California Native plants. Craig’s ever growing catalog of images is stunning, worth following.
Cypripedium montanum, an orchid native to western North America where it grows in montane habitats. With a range barely including California, this species is remarkable for being one of few Californian orchids having large flowers.

Nice flush of Fly Death Fungus in the yard this week. Doing my best to help it along like I use to do at my old apt complex where a single infected fly lead to ~7+ years of zombifies flies. Check out imafungus.biomedcentral.com/articles/10.... for a great overview of their biology

Ran the moth light in the front yard (San Leandro, CA) and turned up this Florida Pink Scavenger (Anatrachyntis badia). With any luck I’ll hit 500 species documented in my yard by the end of the year using iNaturalist.

Hygrophorus goetzei spotted this weekend in what is currently the southernmost portion of its range based upon iNaturalist data. It associates with Mountain Hemlock (Tsuga mertensiana) which continues down to Sequoia National Park, but so far no mushrooms seen there. #rarefungi

Saw my #FavoriteFly today at Lake Tahoe on some Mule’s Ears. The Sunflower Seed Maggot / Neotephritis finalis. It’s the chillest fly you’ll ever meet, all it wants to do is chill on a big soft leaf and maybe lay some eggs in the flowers. #diptera #macro #tahoe

Calochortus luteus also up in the serpentine zones of the Oakland hills right now. Crazy to think of what the serpentine wildflower display must have been like before the Oakalnd hills got developed and homes covered up these highly selective soils #calochortus #oakland #wildflowers

Found 3 previously unrecorded populations of Streptanthus glandulosus today in the Oakland hills by checking google satellite for exposed serpentine outcrops. By far my favorite Brassicaceae (mustard family) of the Bay Area. #Brassicaceae #Streptanthus #oakland #wildflowers

Bog beacons and some sundews from Northern California yesterday. Mitrula elegans is a semi aquatic fungus that can break down plant material in low oxygen aquatic environments. In California you mainly find it in the late spring in the mountains
