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

I am excited to be a mycologist for this foray in Ecuador. Here is what we found on the last one: inaturalist.org/.../ecuador-ad… All collections will be deposited at the INABIO herbarium in Quito for study + DNA barcoding. For more information see mycena.llc/ecuador-foray

A bioluminescent Mycena that I saw in Costa Rica #bioluminescence #mycology

A few things that I found near Colorado Springs a couple days ago.

Mushroom hunting around Mt. Rainier with Mushroom Wonderland: youtube.com/watch?v=G16rS4…

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.

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

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

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

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 mycena.llc The trip includes workshops on plant and mushroom id, taxonomy, and photography techniques

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.

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. #mycology #uvphotography #mushrooms

Sandpipers on the beach in Capitola, California. #birds

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 by Alan Rockefeller and @crime_pays_but_botany_doesnt - seed from Michoacán. #plant

Coprinopsis section Coprinopsis photographed yesterday in Tandayapa, Ecuador. #fungi #mushrooms

Ps. hoogshagenii var. hoogshagenii from Mera, Ecuador. This species is in sect. Mexicanae, though it's on a long branch, so it's not super closely related to anything else. Grows in landslides and disturbed areas. I don't think anyone has cultivated it. #mycology
