This Costa Rica trip starts in 64 days! We will be exploring the biodiversity of high elevation páramo & medium elevation cloud forest habitats. More info: www.mycena.llc/costarica-fo...

Mycena chloroxantha photographed recently in Oxapampa, Peru. The round cells are cherocytes which make up the universal veil - whitish, spiny acanthocytes are also visible. Described in 1983 from Brazil by Rolf Singer. Mushroom Observer # 628987 / iNat 341877230 #fungifriends #mycology #mycena

A cool little Mycena that I photographed in Oxapampa, Perú. Never seen one with this cool stem texture before, no idea which species it could be. Olympus OM-1 / 90 mm macro lens / 180 images stacked, ISO 200, f/5. #mushrooms #mycena #fungifriends #olympus

A cool leafhopper I photographed a couple days ago in Perú. Anyone know what species or genus it is? Reminds me a bit of Molomea but leafhoppers are really diverse.

Ceratiomyxa sphaerosperma from Mera, Pastaza, Ecuador. This tiny slime mold makes its spores on little stalks, giving it a distinctive appearance. My favorite feature of these are the glass-like stems. Olympus OM-1 / 90mm macro lens / MC20 2x teleconverter

Coprinopsis section Coprinopsis photographed yesterday in Tandayapa, Ecuador.

One of my favorite flowers, Lopezia racemosa. Second photo in 365 nanometer ultraviolet. The native range of this plant is Mexico through Central America. Extremely rare in cultivation - grown in California by Alan Rockefeller and @crime_pays_but_botany_doesnt - seed collected in Michoacán. #plants

Sandpipers on the beach in Capitola, California. #birds

A Steller's jay that I saw this weekend at Salt Point State Park, California, USA. #birds

The interior of the peridioles of Nidula niveotomentosa (a birds nest fungus) have surprising green fluorescence in 365 nanometer UV light. Photographed yesterday in Mendocino County, California. Sliced in half with a sharp razor blade. #fungi #mycology #mushrooms #fungifriends #uvphotography

In 2025 I made 3000 iNaturalist observations and found 1582 species, 682 of them I had never seen before. I made 46,000 identifications for other people. I did a 5 month road trip to the southwest and east coast, went to Ecuador twice and Costa Rica once. Also wrote lots of Python (Github)

This is the second time I have photographed one of my favorite Mycena species - this one is found on leaves and has regular water droplets along the stem for a reason which remains a mystery to me. From the Chocó Andino region of Ecuador. #mycology #fungi #mycena #fungifriends

Joey from Crime Pays But Botany Doesn't and I are leading a two-week trip to Ecuador this February with local botanists, mycologists, and herpetologists. Details at www.mycena.llc The trip includes workshops on plant and mushroom identification, taxonomy, and photography techniques.

Metacampanella subdendrophora growing on scotch broom in Pacific County, Washington. #metacampanella #mycology #macrophotography #fungi #fungifriends

Mycena tenerrima from Pacific County, Washington. This tiny and widespread Mycena is in Mycena sect. Sacchariferae due to the powdery cap texture, stem with long setae and disc at the stem base. #fungi #mycology #mycena #fungifriends

Psilocybe azurescens in 365 nm ultraviolet light + white light. Seen a couple days ago in Pacific County, Washington. #fungi #mycology #ultravioletphotography

Lactarius subgenus Russularia found 10 seconds ago in Aberdeen, Washington #fungifriends #fungi #mushrooms

An undescribed Mycena from the M. amicta group photographed yesterday in Aberdeen, Washington. This group of species is recognizable due to the blue colors, especially on the stem base and the conspicuous setae on the stem. #fungi #mycology #fungifriends #photography

An unknown parasite on Xylaria from Pastaza, Ecuador. #mycology #fungi #fungifriends #xylaria

Psilocybe yungensis that I found Feb '25 in Pastaza, Ecuador. This species gets its name from the Yungas region of Bolivia, where it was discovered in 1958. #fungi #fungifriends #psilocybe #mycology #photograhy

It's been a spectacular month in Colorado, but now it's time to head east for the Ohio Mushroom Festival. I'll be leading forays and giving talks - hope to see you all there! ohiomushroomfestival.com

Mycena "sp-AZ03" that Scott Ostuni spotted near Fox Mountain, Colorado last year. I just got a sequence of it back from Mycota Lab. This probably undescribed species currently only known from Colorado and Arizona. iNat 235426392 / MO 556415 #fungi #mycena #mushrooms #fungifriends

The first known photo of Trichoderma sp. ‘TX01’ - a rare and probably undescribed species of Trichoderma I collected on a vine in Texas in November, 2022. The only match in Genbank is an unnamed collection from Florida. iNat 140831069 / MO 581563 #fungi #trichoderma #dnabarcoding #fungifriends

Cirsium vinaceum is an extremely rare species of thistle that only grows in Otero County, New Mexico in high elevation wet areas. Quite a few plants were growing near a mountain spring that I explored today with the New Mexico Mycological Society.

An undescribed bioluminescent Mycena from Mycena sect. Sacchariferae, closely related to Mycena asterina found a few days ago in Monteverde, Costa Rica. Like Mycena asterina, only the cap glows. #bioluminescence #mycena #mycology #fungifriends #fungi

A tiny Favolaschia found yesterday in Monteverde, Costa Rica. These are basically in Mycena and will probably be moved into Mycena soon - the alternative is to split Mycena up into a whole bunch of similar looking genera. #mycology #fungi #fungifriends #favolaschia

I have tried lots of different types of black velvet for photography and this one is my favorite. It is thicker and more durable than most other black velvet that I have tried, and absorbs light from more angles. www.ebay.com/itm/38341711...

Entoloma quadratum from the White Mountain National Forest, New Hampshire in August of 2023. ID verified by DNA barcoding at Mycota Lab. This species was described in 1859 in New England, just a couple years before the civil war. iNaturalist # 178764994 / MO # 550987 #fungifriends #fungi

Entoloma sp. ‘IN13’ photographed in Harford County, Maryland. Sequenced by Mycota Lab. MO 525589 / iNat 176624713 #mycology #dnabarcoding #fungi #fungifriends

Callistosporium pseudofelleum, an extremely fluorescent little white mushroom that is really easy to identify with UV light. From Harford County, Maryland. Sequenced by Mycota Lab. iNat 176666288 / MO 525590 #fungifriends #mycology #dnabarcoding #uvphotography

In the field I thought this was Infundibulicybe gibba, but I just got a DNA barcode back from Mycota Lab and this turned out to be Infundibulicybe squamulosa. I. gibba has a lighter cap color and prefers hardwoods while I. squamulosa grows under conifers. iNat 178021816 / MO 526599 #fungifriends

Hygrocybe "parvula-PNW01" photographed in New Hampshire and sequenced by Mycota lab. Hygrocybe parvula was described from New York in 1875, so it's likely that this is the real H. parvula. MO 526630 / iNat 178299999 #mycology #fungifriends #dnabarcoding
