Observation 210279: Ganoderma oregonense Murrill
When: 2015-07-11
No herbarium specimen
0 Sequences

Large baseball sized knob protruding from a very pithy, degraded Western hemlock log. Fruiting bodies are found on this substrate from mid July-September periodically. Annual fruiting of G.oregonense and G.tsugae are a regular collection for our pantry every season. Cold and flu season are a cool breeze when using these PNW strains for tea. NOTE: start your weekly regimen of daily shots(in the A.M.) of Reishi tea around mid August and continue until January for best results.

*Never harvest these fresh Reishi at the “marshmallow stage”(as with this image); rather, wait until the specimens have completely become flat and planed out. As the white leading edge decreases in mass of the cap- the chocolate brown spore bearing structure will increase in height and almost completely fill the cap. Harvest when spore mass has covered the cap of specimen and the entire fruiting body is deep chocolate brown when sliced. This will ensure that adequate spore dispersal in the habitat will continue each and every year(as these are annual polypores). If all were to be harvested at the stage of the sporophore in this post we would run out of reishi within a few summers. I have successfully harvested at this location for more than just over 8 seasons now. I have introduced many strains of Ganoderma here, as well. Most harvest and transplant of stem butts came from Mora campground and 3rd. beach WA. We even successfully inoculated the end of an already proliferated(with G.applanatum and F.pinicola) Western hemlock log. The following year in a one foot section of the log were very large, marshmallowing G.oregonense in the exact location we inoculated. Fun to try for all ages, awesome to spread medicinally valuable fungi throughout the world. This location is a city park and has always been a fail safe for reishi to harvest each summer.

Elevation: sea level.

Temp: low 90’s.

Glad to know there is someone else out there infatuated with polypores! Looking forward to seeing future progression.

Nice Knob/nub-

I love how beautiful they are at this stage. I did a few time laps images where I would return week to week to show how rapidly these varnished Gano’s can fruit. I like to get em in mid September when the pith is thin and the woody spore structure is dense. Better to look at when young in my opinion. You can see why the ancient Chinese emperors of old were obsessed with them. So striking!

Good luck with your harvest back East!

Spores truly,

Should progress into a great looking autumn mushroom. Nice description. In the south-east I make tea with the G. Curtisii here.
