Porcelain Fungus ( ripe specimen )

Oudemansiella mucida (Schrad.) Höhn. 1910


Oudemansiella mucida, the Porcelain Fungus, is specific to beech wood. It appears in autumn on dead trunks and on fallen branches, and occasionally it also grows on dead branches high up in living trees. Provided that the skin is peeled from the caps, these mushrooms are edible (although their slimy covering is enough to put most people off). Only larger caps are worth collecting, because the flesh is quite thin ( http://www.first-nature.com/fungi/oudema... ) -----The Porcelain Mushroom, Oudemansiella mucida, is sometimes referred to as the Poached Egg fungus - a reference to the white of the egg rather than the yolk, of course! This fungus is weakly parasitic upon beech trees, and on breezy days in autumn it is not unusual to see what appear to be tiny parachutes falling from high branches after the fungi have been dislodged by the wind


location: Europe edibility: Edible fungus colour: White to cream stem type: Lateral, rudimentary or absent, Ring on stem flesh: Mushroom slimy or sticky spore colour: White, cream or yellowish habitat: Grows in woods, Grows on wood Oudemansiella mucida (Schrad. ex Fr.) Kühn. syn. Armillaria mucida (Schrad. ex Fr.) Kummer Buchen-Schleimrühling, Collybie mucide Porcelain fungus. Cap 2–8cm across, convex then flattening, pale greyish when young becoming more white often with an ochraceous flush at the centre, semi-translucent, slimy. Stem 30–100×3–10mm, white striate above the membranous ring, slightly scaly below. Flesh thin, white. Cystidia thin-walled cylindric or utriform. Spore print white. Spores subglobose 13–18×12–15m. Cap cuticle hymeniform, of erect club-shaped cells. Habitat on the trunks of beech, often high up and in large clusters. Season late summer to late autumn. Common. Edible after washing to remove gluten. Found In Europe ( http://www.rogersmushrooms.com/gallery/D... )


Azoxystrobin was discovered during research on Oudemansiella mucida and Strobilurus tenacellus, which are small white or brown coloured mushrooms commonly found in the Czech forests. Not bigger than a few centimeters, these mushrooms attracted attention of scientists because of their remarkable ability to defend themselves. Their defense mechanism is based on the secretion of two substances, strobilurin A and oudemansin A. These substances allow them to keep their competitors at a distance and even destroy them when in range. Observations of this mechanism led directly to research that resulted in azoxystrobin ( http://en.wikipedia.org/wiki/Azoxystrobi... ), ------ ( http://www.mycobank.org/MycoTaxo.aspx?Li... ), ( http://www.kijkenindenatuur.nl/paddensto... ), ------ in the last picture do you see the white discoloration through the spore-release, which therefore indicate "white spores"!! sometimes it is very easy to get the color of the spores without spore-print!!
