Observation 200715: Laricifomes officinalis (Batsch) Kotl. & Pouzar

When: 2015-03-19

Collection location: Cascades along Highway 12, Washington, USA [Click for map]

Who: Drew Henderson (Hendre17)

No specimen available

Fruiting 50ft. up a dying Larch(Larix occidentalis).

Note: How proliferated this old Agarikon is with charcoal looking black crust surrounding it(each year I see tiny black spots on fresh growing specimens we monitor, especially above 3500ft). I have noted in other observations that black fuzzy mold(which I think is just Aspergillus niger) attacking both young and old specimens of Laricifomes officinalis, especially on the leading pore surface underneath.

Elevation: 3,400ft.

Temp: mid 50’s.

Note black mold surrounding each year of growth.

Done sporulating-wish we could extract this to get a closer view of this relationship between aspergillus and Agarikon.

Hoping this will spark some interest as to why such a powerful antibiotic substance(most powerful antibiotic created by nature at least) is beginning to be over run by common black mold. I also had a thought as to Cryptococcus Gattii(http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2725832/) possibly being a recent factor(and instead of appearing to be nothing but dust in the afternoon canopy light; perhaps Agarikon are the canary in the cave for Cryptococcus and other sever lung pathogens by revealing for us the black spots in areas proliferated. I also noted in the last month that between 3000ft and 5500ft elevation along the larch line and lodgepole- all Usnea and other monte lichen species were charred and appeared black, as well. They literally are the lungs of the forest(along with mushrooms and trees and the multiple exchanges they all share, oxygen carbon dioxide, etc.). Martin, did you remember seeing this more abundant than years past while up Rainier this last year?

Would love any and every bit of input from all MO members who are familiar with this phenomenon while in the Cascades/PNW, or anywhere.

Nice observation!
