Armillaria ostoyae is a fungus commonly known as a Honey mushroom, and sometimes called Shoestring Rot.

This is the most common variant in the western U.S., of the group of species that all used to share the name Armillaria mellea. Armillaria ostoyae is quite common on both hardwood and conifer wood in forests west of the Cascade crest. The mycelium attacks the sapwood and is able to travel great distances under the bark or between trees in the form of black rhizomorphs ("shoestrings").

A mushroom of this type in the Malheur National Forest in the Strawberry Mountains of eastern Oregon, U.S. was found to be the largest fungal colony in the world, spanning 8.9 km² (2,200 acres) of area. This organism is estimated to be 2,400 years old. The fungus was written about in the April 2003 issue of the Canadian Journal of Forest Research. While an accurate estimate has not been made, the total mass of the colony may be as much as 605 tons. If this colony is considered a single organism, then it is the largest known organism in the world by area, and rivals the aspen grove "Pando" as the known organism with the highest living biomass.

In 1992, a relative of the Strawberry Mountains clone was discovered in southwest Washington state. It covers about 6 km² (1500 acres).

Another "humongous fungus" is a specimen of Armillaria bulbosa found at a site near Crystal Falls, Michigan covers 0.15 km² (37 acres), and was published in Nature 356:428-431.

fine image and wonderful notes to make this a very interesting and worthy upload,,,TFS

Hello Gert,
Vraag me een beetje af de heel lage ISO van 64 geen ruis genereert. Een beetje zichtbaar in de donkere achtergrond, vind ik. Enig minpuntje.
Wederom leuke compo, enz...
Bedankt
Annick

You make me curious again about fungi. Only once, a fall about 20 years ago, did I go in a forest to pick up mushrooms. I had bought a book and I remember the intense surprise I had by finding so many different species, all there in front of us, without seeing them! It's incredible. ANd you are a master in photography too, your pictures are always beautiful and well composed and at the same time, we can identify the fungi. Your notes are also very interesting, thank you for your great contribution on this site.

Hallo Gert,

Van deze Honingzwam had ik nog nooit gehoord. Zo zie je maar dat je iedere dag nog kunt leren op deze aardbol (-: Als ik de kritiek van Annick lees dat je een heel lage ISO waarde van 64 heb gebruikt en daardoor ruis in de achtergrond krijg, heb jij dan dezelfde ervaring hiermee. Ik fotografeer haast altijd met ISO 50. Heb zelf een Canon G5. Zet hem nooit op automaat wat betreft ISO waarde. Maar heb zelden ruis op de achtergrond. Terug naar jouw schitterende foto. Kleurrijk, zeer scherp (gebruikelijk bij jou) mooie compo en een uitleg waar je als mens haast stil van zou worden. Vooral het ondergronds mycelium omvang van 8,9 km² !!!!!. Bedankt voor het delen en de les. Prettige dag en tot TFS BOB
