Found growing from a dead branch on the ground. It appears to be quite old and somewhat rotted. Cap is cream to white colored and nearly kidney shaped. Approx cap size is 1 1/2 inches wide. Underside of cap is tawny or tanish in color and features tiny pore like “gills”. The stem color is much like that of the underside of the cap but a bit darker and peachlike then it darkens to an almost black tint 1/4 of the way down to the very end. Stem length approximatley 2 to 2 1/2 inches long. There appears to have been another growing along side of this one but it wasn’t there any longer. The stem is not located in the middle of the cap but off to a corner. The underside margin is darker then the rest of the underside. Firm texture.

I am totally in the same boat although my obsession is in its half season infantcy. My personal expieriences on here have been very relaxed and highly informative but I do see others who have been slaughtered for their opinions to the degree that I feel severly incompitent to even ID anything. Hopefully I’ll progress. Happy hunting!

but what others may see as pompous I see as a different language: the language of mycology. You did not make a mistake, goatshoes. But I don’t always know how much training others have had in mycology. My personal knowledge is so bad I worry about whether I am communicating, sometimes.

Any mycological terminology I use, I’ve learned (sort of) over the past 25 years. I’ve had some good assistants. But I’ve never had a class in mycology in my life.

Yep, that’s probably the problem!

I have noticed how many people on here can be quite pompous or belittleing when it comes to details so I try to go out of my way to be as open and polite as possible so as to never be tossed in the clique with those improper attitudes. I just want to learn! :-) so I sincerly thank you for pointing out my mistake!

No, thank you! I thought maybe gills was a generic term for the place wheree spores are released from but now I clearly understand…so thanks again!

Sorry, goatshoes.

Didn’t know what you meant by “gills”. To me, “gills” means something different.

Thanks for the thanks – it is appreciated.

No Gills

Correct…hence the parenthesis around the word “gills”….but I’ll be sure not use the word next time. Thanks.

No gills.

Polyporus means “many pores”. There should only be pores (shallow tubes) on the underside. Gills are defined as knife-blade-like structures, which produce spores on the sides of the knife-blade. Oyster mushrooms (Pleurotus) have gills. Boletus mushrooms (like porcini) have pores.

Yes, I made a note of that stipe characteristic in my initial notes above. Thanks for the ID!

Likely a small Polyporus badius or close ally.

Note the stipe (stem) which has a much darker base near the branch.
