De l'art conceptuel hyperréaliste ?

A very thin, wet, and dark brown twig enters the frame from the top right corner and ends in the center of the frame. At the end of the twig, a strange blob or orange, fluid-like stuff clings on, looking like tangled orange intestines. A tiny bubble of air is trapped at the center of the tangled mass. This weird orange stuff is a slime mold - an organism that crawls around in search of food, changing its shape as it matures from a liquidy mass to a hard, often tree-like spore dispersing form. 📷 Canon R5 Canon RF 100mm f/2.8L IS USM M, f/2.8, 1/10, ISO 400 Stack of 16 images 11/15/24 Northern Oregon Coast

Not a mushroom, but a slime mold! This very peculiar thing appears to be part of a slime mold that crawled onto the end of this stick and had nowhere to go

Photo taken within a stand of Rhizophora mangle. The trees are growing in water, and masses of roots arch out from the trunks while others drop from branches. Photo by Scott Zona CC BY-NC 2.0.

Mangroves have aerial roots that stabilize these trees against tidal currents & waves. Rhizophora mangle is a perfect example. The aerial roots (some emerging from other roots) stabilize the plants & capture sediment. Rhizophora means “root bearer.” #Rhizophoraceae #root #Botany 🌾🧪🌱

To see prop roots on a larger scale, look to the palms and pandans. 📷1: Clinostigma harlandii, a palm. 📷1: Pandanus sp (to get an idea of the scale of this giant, check out the green cap in the lower left). #Arecaceae #Pandanaceae #root #Botany 🌾🧪🌱

Close-up photo of the bases of corn stalks. Adventitious roots emerge from nodes above the soil surface and grow downward. Roots from lower nodes have penetrated the soil, while those from upper nodes have not yet touched the soil.

This week is devoted to #roots we can see, like these from corn/maize (Zea mays;📷: 305 Seahill CCBYND2). Corn is famous for its prop roots that emerge from the stem above the soil line. When they penetrate the soil, they brace the main stalk. Structural engineering! #Poaceae #Botany 🌾🧪🌱

Growing out of a thick bed of bright green moss, multiple pink and red mushrooms of different heights pop up. The two mushrooms in the center are the focus. The one on the left is shorter than the other, the top of its cap just reaching the bottom of the other's. Their stipes are a dull, dark pink and are just slightly rough in texture. The red, round caps are smooth and shiny. On the right mushroom, a tiny bug called a springtail is visible climbing up the stipe. 📷 Canon R5 Canon RF 100mm f/2.8L IS USM M, f/4, 1/6, ISO 400 Stack of 18 images 11/14/24 Northern Oregon Coast

The tiniest springtail clings to the stipe of a growing Mycena haematopus, the bleeding Mycena. This mushroom, when cut or damaged, exudes a dark red liquid resembling blood

A beautiful shiny orange mushroom emerges from wet dark brown soil. Its smooth yellow stipe slants out of the earth at about a 45° angle to the right before turning straight up beneath the cap. The orange cap is a bit small and opens up just around the stipe. 📷 Canon R5 Canon RF 100mm f/2.8L IS USM M, f/3.5, 1/4, ISO 400 Stack of 44 images 11/23/24 Olympia area, Washington

I'm unsure of the species of this cute orange mushroom, but I believe it's a type of Gliophorus. It might even be Gliophorus psittacinus (which iNat also suggests)

Hauya elegans (📷: Tony Rodd CCBYNCSA2) is a tree from Mexico & Central America. It has classic #Onagraceae flowers: long hypanthium tube, reflexed sepals, capitate stigma (like Fuchsia et al.), inferior ovary. And it has color-changing flowers that start white and age to dark pink. #Botany 🌾🧪🌱

Several officials told me that Patel’s drinking has been a recurring source of concern across the government. They said that he is known to drink to the point of obvious intoxication, in many cases at the private club Ned’s in Washington, D.C., while in the presence of White House and other administration staff. He is also known to drink to excess at the Poodle Room, in Las Vegas, where he frequently spends parts of his weekends. Early in his tenure, meetings and briefings had to be rescheduled for later in the day as a result of his alcohol-fueled nights, six current and former officials and others familiar with Patel’s schedule told me. On multiple occasions in the past year, members of his security detail had difficulty waking Patel because he was seemingly intoxicated, according to information supplied to Justice Department and White House officials. A request for “breaching equipment”—normally used by SWAT and hostage-rescue teams to quickly gain entry into buildings—was made last year because Patel had been unreachable behind locked doors, according to multiple people familiar with the request. Some of Patel’s colleagues at the FBI worry that his personal behavior has become a threat to public safety. An FBI director is expected to be available and focused on his job—especially when the nation is at war with a state sponsor of terrorism. Current and former officials told me that they have long worried about what would happen in the event of a domestic terrorist attack while Patel is in office, and they said that their apprehension has increased significantly in the weeks since Trump launched his military campaign against Iran. “That’s what keeps me up at night,” one official said.

Le directeur du FBI « est connu pour boire jusqu’à une ivresse évidente », au point d'avoir « des difficultés à [se] réveiller, apparemment en raison de son état d’ébriété ».

« Certains au FBI craignent que son comportement personnel ne constitue désormais une menace pour la sécurité publique »

The FBI Director Is MIA Kash Patel has alarmed colleagues with episodes of excessive drinking and unexplained absences.

Un ministre de la défense agressif & masculiniste qui cite une tirade de Pulp Fiction en pensant qu'il s'agit de la Bible.

Et un directeur du FBI incompétent, instable & alcoolique (l'article de The Atlantic est édifiant).

A gorgeous green and yellow mushroom, called the parrot mushroom, grows out of dark brown dirt with a touch of green moss at its base. Its stipe is bright yellow, smooth, and has an interesting and faint alternating pattern of darker and lighter yellow. The cap is an emerald green color - lighter around the margins and darker at the top - with vertical striations of dark green around the edge. Tiny bugs called springtails are dotted across the mushroom. 📷 Canon R5 Canon RF 100mm f/2.8L IS USM M, f/4, 1/2, ISO 400 Stack of 33 images 11/20/24 Olympia area, Washington

The springtails were having a party on this colorful parrot mushroom. Sometimes I prefer completely prestine mushrooms for my photos, but sometimes its okay to let the springtails join in, too 🐛🕺

No rare lichens, just a pretty photo. A Tilia sp, probably T. cordata, bud poking through Ramalina fastigiata, R. farinacea & Parmelia sulcata, in High Weald Buxted Park. Tilia cordata are native to the High Weald; but were also planted on boundary banks in tall forest and in pasture woodland
