Observation 204488: Laricifomes officinalis (Batsch) Kotl. & Pouzar

When: 2015-05-16

Collection location: Millersylvania State Park, Thurston Co., Washington, USA [Click for map]

Who: Drew Henderson (Hendre17)

No specimen available

Fruiting approximately 45-50 feet up this extremely large Douglas fir.

Canopy is predominantly old growth Douglas fir, 2nd growth Douglas fir, Western hemlock, Spruce, red alder, Western red cedar.

Shrubs: Salal, Oregon grape, sword fern, huckleberry, and evergreen huckleberry.

Elevation: Sea level.

Temp: low 60’s. Frequent showers.

This conk was whitish green prior to recent rainfall. When wet the greenish tinge blossoms into a deeper kelly green hue on most long Agarikon specimens like this one. Adolf and Aluna had a very similar conk they have been monitoring for years. We have also noted over the years, while monitoring Agarikon, that the higher in the tree they are fruiting, the longer and more cylindrical the fruiting bodies grow. Low stump growing forms(found at your feet) seem to be more wide and thick growing. Growth years are thicker(about 2-4 inches thick for ground fruiting Agarikons)- while the long tree droopers have extremely thin year rings and can grow more than 50 years. The one in these images is well over 40 from my count. Feel free to count them and post a comment if you have a more astute eye with this. Again, apologies for the zoom blur.

Years of algal and lichen build up have turned this Agarikon green-with tinges of brown, white and tan on all rings. Leading growth ring is white/tan and deep chocolate brown on leading margin.

Obtaining the Sample and Cloning this strain will be a challenge no doubt- going to have to get creative…. Anyone on MO have helicopter access???
