An annotated ITS tree of sect. Semilanceatae dikarya.us/job/eeor/view

Coprinopsis nivea found on a foray this weekend in New Mexico. Growing on cow dung in the Jemez mountains. First photo cut in half with a brand new razor blade. Likely actually Coprinopsis sp. 'nivea-AZ01', see dikarya.us/job/3611f65f-bf20…

Gomphrena pulchella (globe amaranth) photographed in 365 nm UV light at the Denver Botanic Gardens.

Pectiantia pentandra in 365 nm UV light. Someone handed me this leaf during a UV night hike above Boulder, Colorado the other night and I was blown away by its beauty. The bright yellow fluorescence is due to the presence of quercetin and kaempferol glycosides.

A few of his tips I found most useful: shoot the face of an insect from below, looking up at it. The back is what you need for ID, but the face is where the personality is. Pick moths up off the moth sheet with a leaf - they look much nicer on a leaf than on the sheet.

I brought a 50 watt ultraviolet light (395 nanometers) to Costa Rica and it attracted a lot of cool stuff to the projector screen I am using as a moth sheet.

Take a tour of my garden as I demonstrate the Mycena LED 10x magnifying loupe. It has white an UV LED's and charges via usb-c. This product is officially back in stock!! We will be shipping every day until we head to Costa Rica in June. My website: mycena.llc/merch

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

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.

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

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
