Saterday I have been photographed a lot of new species for me and also a few very reare fungi that I posted later.
This one is an common fungi but an very beautiful specie.

Latin name - Cystoderma amianthinum

Cystoderma amianthinum

[Basidiomycetes > Agaricales > Tricholomataceae > Cystoderma . . . ]

by Michael Kuo

Perhaps the most widespread and common Cystoderma species worldwide, Cystoderma amianthinum is found with some regularity in northern and montane (including Appalachian) regions of North America. It is usually found growing in moss, under conifers.

Distinguishing physical features for Cystoderma amianthinum include the yellowish brown to yellowish cap; the dense coating of granules on the cap and stem; the fragile and ephemeral (rather than sturdy and persistent) ring; the usually pungent odor; and the reddish to reddish brown reaction of the cap surface to KOH. Under the microscope, Cystoderma amianthinum has amyloid spores and pileipellis elements that are rusty brown in KOH. Several varieties have been described; see the comments below for details.

Edibility is not reliably recorded for Cystoderma amianthinum, and it could easily be confused with several deadly poisonous species of Lepiota. Couple this information with the fact that the mushrooms usually stink, and I would imagine you'll want to keep Cystoderma amianthinum away from your kitchen.

Description:

Ecology: Saprobic; growing alone, scattered, or gregariously, usually in moss under conifers; late summer and fall (over winter in California); widely distributed in northern and montane North America.

Cap: 2-5 cm; dry; convex, obtusely conic, or bell-shaped at first, becoming broadly convex, broadly bell-shaped, or nearly flat; frequently somewhat wrinkled in radial patterns (strikingly so in one version); covered with mealy granules; pale reddish brown to yellowish brown or yellowish.

Gills: Attached to the stem; close; whitish becoming pale yellowish.

Stem: 3-7 cm long; 3-8 mm thick; more or less equal, or tapering to apex; dry; pale and fairly smooth near the apex, but sheathed with granular material and colored like the cap below; the sheath terminating in a flimsy ring that often fragments or disappears.

Flesh: Whitish; thin.

Odor and Taste: Taste mild; odor usually pungent and unpleasant.

Chemical Reactions: KOH on cap surface rusty red.

Spore Print: White.

Microscopic Features: Spores 4-7 x 3-4 µ; elliptical; smooth; at least weakly amyloid. Cystidia absent. Pileipellis elements with rusty brown walls in KOH; chained together; inflated; subglobose

Hello Gert,

You have made a nice photo with the mushrooms showing them in a sharp image. As you have chosen a well adapted DOF the whole mushroom is in focus and even finest details can be sharply seen. The soft light you have chosen renders fine mushrooms colors as well as those of the background.

Thank you for sharing,
Cristian

Hello Gert,
What a superb capture of tese beautiful fungi with 'shaggy' stems. I don't think I've seen this species altough it should be common here too! Excellent sharpness and beautiful light and colours. A very nice background too.
Many thanks and best wishes, Ulla

Hello Gert,

Very nice capture of this beautiful fungus. Very good POV and composition. Great DOF. Good sharpness. Well-saturated colours. Last Saturday we missed the sun in Brussel :-( . I am very happy that you are busy with new pictures taken this year. I went to a small forest yesterday and could not find very interesting fungi to shoot.
Have a nice day,
Cheers,
Mariki

I love the colors and composition!

Hi Gert

A very attractive fungi and you've captured it very well.
Great sharpness and details
Excellent composition and POV

Hi Gert,

Beautiful photo, but the ID specification's wrong. Nice warm color tones, exceptional composition with main and complementer theme, sharpness is second to none. Brilliant image. But I'm a bit surprised nobody realized the photo shows Pholiota flammans instead of Cystoderma amianthinum, very-very different. All species of Cystoderma genus grow on the ground, not on rotting wood as we see on Your image. C. amianthinum is never having such vibrant yellow colors (rather ochre, ochre-brown) and so big granules on the stem and cap surface.

But the wrong ID specification doesn't mean the image would be technically any bad, so tfs. Best regards, László
