English name : Death Cap – Scientific name : Amanita phalloides – Family : Amanitaceae - Not edible : mortal.
---
Description : Pileus : Cap 3.5-15 cm broad, convex, expanding to nearly plane, at maturity the disc sometimes slightly raised or depressed ; margin entire, seldom striate, or if so, obscurely so ; surface subviscid when moist, smooth, occasionally with a faint, appressed, white universal veil patch ; color : olive, olive-brown, to yellowish-brown, rarely white, typically with innate, darker streaks, the margin paler, fading overall to dull tan in age ; flesh soft, white, moderately thick at the disc, unchanging, at times yellowish-brown just below the cuticle ; odor slightly pungent ; taste mild.
Lamellae : Gills free, close, moderately broad, white becoming cream, staining pink to vinaceous with concentrated sulfuric acid.
Stipe : 4-18 cm long, 1-3 cm thick, equal to tapering to an enlarged, sometimes bulbous base, usually solid but the apex sometimes stuffed ; surface finely striate at the apex, otherwise smooth or with scattered, flattened small scales, white to pale yellowish ; flesh white, firm, unchanging ; partial veil membranous, cream-colored to tinged like the cap, the upper surface striate, lower surface slightly pubescent, forming a pendulous, superior annulus ; volva membranous, thin, white, sac-like, usually erect from the stipe.
Spores : 7-12 x 6-10 µm, ovoid to elliptical, amyloid ; spore print white.
Habitat : Solitary, scattered, to gregarious under Coast Liveoak (Quercus agrifolia), occasionally with other oaks and ornamental hardwoods ; fruiting sporadically during the summer months in watered areas or from fog drip along the coast ; common from early to mid-winter.
Edibility : Deadly poisonous ! Amanita phalloides contains both phallotoxins and amanitins. It is the amanitins that are responsible for the poisonings in humans. Amanitins are cyclic octapeptides that stop protein synthesis in the cells they encounter. All human organs are effected, but damage to the liver is most severe and liver failure is primarily responsible for the death of Amanita phalloides victims. Symptoms usually appear 8-12 hours after ingestion. Death occurs in 7-10 days in 10-15% of patients.

I made this picture the evening in forest, you imagine the low light and I don’t like flash on fungi, so it was difficult at speed 1/5s without tripod in a wet slope…

Very nice photo of this dangerous Amanita. Very good composition, sharpness and colors. In my country this Amanita is most poisonous mushroom of all species. It is very common mushroom in oak-hornbeam forests.

So this pretty, harmless-looking mushroom is a real baddie! I've heard of the DeathCap before Taz, but it looks so normal. Yet reading your very interesting notes I see it does have various colours. I will never eat any mushrooms I find now.
I like your lighting here, and your POV too. Well done. TFS.

Hi Christian,
excellent composition, like a classic still-life. The cone in front and the twig behind in two different vectors add depth to the picture. Only one nit: focus is a wee bit too forward, noticeable on the pinecone in front which is sharper than the mushroom.
Regards,
Gabi

Bon week-end!

Wonderful pastoral forest scene, great colors and perfect lighting.

TFS!

Bonjour Christian,
Ce petit champignon est bien joli et il a pourtant l'air si inoffensif! J'aime bien votre composition ainsi que le point de vue et les détails. Merci pour la note!

Très beau cliché Christian, et merci de bien préciser que ce champignon est mortel et que chaque année quelques personnes meurent empoisonnées par manque de vigilance ou par ignorance.

Hi Christian, A superb composition, I love the DOF with all the other elements around the main subject in good detail. This gives perfect scale to the viewer. My further education with your notes is very helpful. A truly great job!

HI Christian,
Nice shot. I won't be eating this one.
I like your composition and the space you have left around the fungi.
:)

Great shot. I like the simple composition and having the pine cone next to it adds interest. Good DOF.

Regards,

Tom
