Andrew is who I was going to send it to for sequencing so that saves me a shipment. I will still do thorough microscopy.

I mailed it today.

Andrew from UF, i sent yours out today as well.

Got your email…
Sent a response. Hopefully you get it this time, apparently last correspondence thru here didn’t come thru until an admin forwaeded it. Anyways, let me know about drop off of specimen, since you are only 30 mins away from where i am. Thanks

Emails from you both, and will send a sizeable chunk. They are dehydrating as we speak and i can send out tomorrow. I am thinking of heading back up to take picture of the tree it grew from.

Yes, I am fairly certain this is G.oregonense. It is a very useful specimen to study because it adds another data point to Ganoderma varying its host preference.

I will do microscopy on the spores and send a bit out for sequencing. I have a small collection of “anomalous” tsugae from birch, maple, and oak. I have seen oregonense posted by people who found it on hardwood but haven’t managed to get a sample for confirmation yet. So this is an exciting specimen.

Are you collecting this and are you going to sequence it?

Ganoderma polychromum has a brown flesh with vivid striations, not a white flesh…

Email, will send specimen out to you on Thursday. Also posting a new pic here on M.O. of the flesh so you get a better look. Keeping in touch, Danielle

Is not native to the US though there seems to be some possible isolated populations out west. Lucidum however has a brown flesh. Microscopy should be able to distinguish as oregonense has slightly larger spores than lucidum. DNA testing would also help.

It is possible to find Ganoderma tsugae on Oak and Maple on the very rare occasion here in the East. G.oregonense is a close relative to tsugae so it is not outside the realm of possibility.

Other species like G.sessile and G.curtisii that tend to grow on hardwoods have also been found on conifers. Tree host is not as strict as was once believed.

Sent an email, very interested in examining this specimen.

Not organese seems to fit due to this was growing on a maple tree.

Was all white, but it stained brown like it looks in the photos from me hanging off it to get it down from the tree, leaked brown goo all over and stained the pores, and stuff.

Oh, and

Yes, hardwood. Likely a maple.

A sample. I’m getting spore prints tonight. I will send you a chunk. :●)

And it for sure was found on hardwood?

I think that this is G.oregonense based on that description. Occasionally here in the east we get G.tsugae growing from hardwoods.

I would be interested in studying a sample if you would be so willing to send me some.

It is light beige

What color is the internal flesh?
