My partner just told me that our 1st batch of sequences are back from the lab. Can’t wait, will post.

Especially in polypores and crusts

there is so much work left to be done. In France alone they describe many species each and every year and sometimes only minimal microscopic features distinguish them. When DNA’ed they for the most time really represent independent species!
Unfortunately the French people are still hesitating to publish in other language than French or in international journals so many mycologists do not acknowledge and recognize their work and species still.
I use Olympus and am very satisfied with this.

I have had access to a better scope for the last 3 months and I now agree with you. I am in desperate need of a scope. …a good one that I can get to without a lot of trouble. I wish I had one tonight.

Thanks for the suggestion John

..and I don’t mind sending these to Gerhard either. Picking out a good scope seems to take more knowledge than I have at the moment, and budget is always an issue. I do often feel in desperate need of a mic. Until I get one, I have to focus on being a good FIELD mycologist and there is still a lot to learn there.

save some of them unusual ones like this and bring them to one of the larger forays where we can scope the. I have the european set of books on them.

You are in desperate need of a microscope

a.s.a.p. … or if you already have one, try to mic this one …

I appreciate your effort!

How I wished to come up with a name!

But it is impossible to me. You need an expert from America for this. It certain looks like thousands of other resupinate polypores :(

It is definitely poriod

As it is near my house, I went out with a better camera. No smell was noticed. Even if it is not a crust, it still deserves a better name than polypore..,!

Sorry for disappointing you,

but this is a polyporoid mushrooms. Scytinostroma is a crust fungus and has no pores. Was the smell really that nauseous as is in S. portentosum?
