Psathyrella piluliformis (I guess, any suggestion are welcome)

Today I post this beautiful mushroom which is able to tolerate quite cold temperatures. Psathyrellas are very tricky, they are quite easy to recognize when small but they can grow scattered or clustered, colour varies several times while growing and shape is incredible different depending on the growing conditions.

Some info:
Pileus: Cap 2-4.5 cm broad, convex, broadly convex at maturity; surface smooth, moist, hygrophanous, chestnut-brown to rusty-brown, fading to yellow-brown to tan, the margin usually darker and appendiculate with veil fragments, the latter white, then dark-brown from maturing spores; flesh pallid, thin, fragile.

Lamellae: Gills adnate, crowded, narrow, light-brown becoming dark-brown in age.

Stipe : Stipe 2-7 cm tall, 0.3-0.7 cm thick, hollow, fragile, equal or the base slightly enlarged; surface white, smooth; veil white, fibrillose, soon deciduous, remnants left on the cap margin or forming a faint superior annular zone.

Spores : Spores 4.5-6 x 3-3.5 microns, elliptical, smooth; spore print dark brown.

Habitat : Grouped or clustered, usually at the base of hardwood stumps; fruiting from late fall to mid-winter.

Edibility: Questionable. Described as edible in some texts but not substantial enough to be of culinary value. There is also the possibility of confusing this mushroom with the potentially deadly Galerina autumnalis.

Comments: The genus Psathyrella is a large group, many of which are very difficult to identify, Psathyrella piluliformis (hydrophila) is one of the few species that is relatively easy to recognize (although I am not sure). It is distinguished by a clustered fruiting habit, usually at the base of hardwood stumps, a hygrophanous brown cap with appendiculate veil fragments that in age become colored with maturing spores, and a white, fragile stipe. Galerina autumnalis, a mushroom containing deadly amatoxins, is similar in color and size, but has a viscid/sticky cap when moist, the cap margin is typically striate, not appendiculate, and the spores are rusty-brown rather than dark brown.

Hope you like!

Hi Filipe

Indeed a very beautiful mushroom presented in a lovely photo!
The geometrical 3D shape of this fungus is exceptional and makes such a beautiful composition.
I really like the was you managed to keep all teh 4 hood is full focus here - very good usage of (what i think is the maximum) DOF of your charming, mobile and practical Sony.
The sharpness of the details is terrific and all the colors and tones are very beautiful, thanks to the correct exposure here.

Bravo and TFS

Your mushroom pictures are a delight to watch, Felipe.
This is perhaps one of your best on the theme.
It is a wonderful composition with this symmetrically arranged bunch of them growing out of the moist earth.
Amazing sharpness and beautiful colours.

Hello my Friends!
Wow! I just do not know what to say. All your picture are so fantastic that any other comment is not necessary :)
Fantastic "family" picture with perfect details and very interesting note.
TFS and best withes,
Radomir

PS. Today in the field I found one Carabus species (Coleoptera: Carabidae) killed by Laboulbeniales musrooms. I just would like to ask if you ever photographed such fungi?

Great POV with perfect sharpness, superb colour and details on this beauty!

Hi Felipe

I can't get over how your Sony takes such beautiful and perfectly exposed fungi.
This is fantastic. Of course the composition and your attention to placing the camera in the right position all help make the perfect shot.

well done my friend
