In the autum of 2006 I made this photo (i think this is a Vermilion Waxcap, but I'm not shure) on the Vlietlanden. A beautifull place nearby Vlaardingen in the SW of the Nederlands. I put the camerabody on the ground.

Vermilion Waxcap (Hygrocybe miniata)

[ Basidiomycetes > Agaricales > Tricholomataceae > Hygrocybe . . . ]
Taxonomy in Transition: Hygrophoroid/Omphalinoid > Hygrophoraceae Group

by Michael Kuo

If you enjoy spending long hours looking through a microscope and pouring over technical mycological treatises, I highly recommend you pick some little orange or red waxy caps, bring them home, and try to figure out what they are. Hygrocybe miniata is not Latin for "many look-alikes," but it ought to be. The mushroom's defining features include its dry convex cap, its gills (which are attached to the stem or begin to run slightly down it, but do not really run down it), its dry stem, and microscopic features. Nearly all of these features--even the microscopic ones--are variable, however, so it's probably not a good idea to bet the house on your identification. A few of the more easily separated look-alikes are presented in the right-hand column.

As a matter of principle, no mushroom that is so difficult to identify should be eaten. Field guides often list Hygrocybe miniata and Hygrocybe cantharellus (see the right-hand column) as "edible," but a sticky-capped look-alike, Hygrocybe punicea, may be mildly poisonous for some people--while edibility is unknown for a fairly large number of other similar looking mushrooms. I do not recommend experimenting.

Description:

Ecology: Saprobic in hardwood forests and mixed woods; on soil or in moss; sometimes on rotting logs; growing gregariously; summer through winter; widely distributed in North America.

Cap: 2-4 cm; broadly convex with an incurved margin when young; becoming broadly convex or nearly flat; dry or slightly moist; smooth or minutely scaly/hairy; scarlet when young and fresh, but often fading to orange or yellow; the margin sometimes thinly lined.

Gills: Attached to the stem, but sometimes beginning to run down it; close or almost distant; thick; colored like the cap or paler.

Stem: 3-5 cm long; 3-4 mm thick; equal; dry; smooth; colored like the cap but fading more slowly.

Flesh: Colored like the cap or paler; thin.
Odor and Taste: Not distinctive.
Spore Print: White.
Microscopic Features: Spores 6-8 x 4-5 µ; smooth; elliptical. Basidia 34-48 µ long. Cystidia none. Gill tissue nearly parallel, composed of cells 7-19 µ wide.

Hygrophorus miniatus is a synonym.

Variable Features

Field guides often distinguish Hygrocybe miniata from Hygrocybe cantharellus on the basis of its attached, rather than decurrent (running down the stem) gills. This feature is variable, however, as the illustrations demonstrate. According to Hesler & Smith (1963), gill attachment in Hygrocybe miniata varies "considerably." They continue:
One would naturally assume that a mushroom with adnexed, ventricose gills was distinct from one in which the gills were truly decurrent. However, after studying many collections we are inclined to doubt the validity of maintaining such a distinction. The gills of [Hygrocybe miniata] are typically bluntly adnate. From this condition they may become ventricose and adnexed if the pileus does not expand completely, or subdecurrent if it does. (158)

The fact that the cap of Hygrocybe miniata often fades from scarlet to orange or yellow should also not be given too much importance; mushrooms, especially red ones, are subject to fading--or not fading--depending on a whole host of conditions the mushrooms have no control over!

Other macrofeatures often used to separate Hygrocybe miniata from look-alikes include the length of its stem, and the scurfiness of its cap. In the case of the stem, however, longer than typical growth can occur when the mushroom has to conquer a soft, deep substrate (sphagnum, for example)--and then there is Hygrocybe miniata var. longipes (nearly identical but with a longer stem) to consider. As for the cap texture, Hygrocybe miniata varies from fairly smooth to fairly scurfy.

Hi Bob

What an interesting hood this fungus has. It looks like one of those Chinese hats one always sees the people wear in the rice paddies. The slightly darkish exposure captured some lovely textures and contrasts on the stem and cap. The colours are well saturated and visually pleasing. Although the frontal edge of the cap might be slightly soft in focus the rest of the fungus are pretty sharp and well defined. The exposure was well controlled and even though there are some sharp backlight in the upper region of the composition it does not really distract. A great and informative note as well.

Good work and TFS.
Regards
Loot

Hello Bob,
Very fine macro with perfect sharpness, vivid colour and details on the fungus captured!
very well composed and well seen indeed
well done, Bob
cheers
Tony

Hello Bob,
This specimen stands out really well!
Very fine details are captured, impressive exposure in somewhat difficult light...
A well composed presentation of educational quality!
Greetings,
Pablo -

Belle photo de ce champignon très bien pris, avec le flou autiur. Belle couleurs et bonne netteté. Amitiés Thomas

bonjour bob
je trouvais etrange de voir un champignon en cette saison mais je vois qu'elle date de l'an dernier.
j'aime la couleur et le POV de cette photo.
la netteté est egalement bonne.

After such a big wright up I hate to say this but you fungus looks to be a Cortinarius. The presence of cobwebby like fibbers under the cap (cortina) is tipical of this group. Nice capture with good colour a little more DOF would have done wonders. TFS

Hi Bob,
I missed this one when you posted it.
Its a lovely shot taken from a good POV
The colour and exposure are good.
I see the fungi expert has put you right about the ID
I'm pretty sure Clive is right about this one too ... perhaps you could update your notes about it sometime.
It is amost definitely a webcap of some kind,either a Cortinarius or Dermocybe.
You could do a Google image search with these names and see what you find.
One possibility is the Cardinal Webcap, Dermocybe cardinalis.
Hope this helps.
Steve
