Undoubtedly this is a Ditiola,

and it strongly resembles Ditiola peziziformis as I know it from Europe. Here it grows on lime tree.

I think this is the preferred name. For now!…


Confusion with spelling.

I did some search for Femsjonia pezizaeformis, and it seems the correct spelling is Femsjonia peziziformis (according to MycoBank.org and some others). Ditiola peziziformis is a synonym. It’s not clear if one or another is preferred at this time – looks like both of them are being used. MO insists on the spelling “pezizaeformis”, though.

Aleurodiscus or Femsjonia?

Initially I thought this was Aleurodiscus sp. The only species I could find the image of (outside of A.oakesii) was A.amorphus, and neither seems to fit the bill. Then I took more photos of the similar looking fungus (see the observation mentioned in the previous comment), where you can see both flat discs surrounded by white fuzz, kind of like in this observation, and lumpy bodies that look like Femsjonia – both seemingly the same mushroom. If both observations are the same fungus, then this one is not Aleurodiscus. If the other observation is different fungus, then we have to find some pictures of other species of Aleurodiscus for reference.

Seems like something virtually unknown here – I didn’t find anything on it from American authors. Yet I’ve seen it at least couple of times. John, could you please verify that the other observation (http://mushroomobserver.org/60984?q=3TCb) is the same mushroom? I have few more photos of that one if necessary.

I doubt it

I remember considering Lachnellula and that other genus but then decided otherwise. These mushrooms completely lack stalk or stem and pressed firmly into the wood instead. Also, they don’t curve upwards forming cups, but resemble flat-headed pins stuck into the wood all the way.

Sorry, no

It’s an older photo when I didn’t realize the importance of such details in mushrooms identification. The pine trees were numeroous on the spot, i’d say dominant species, but there were few red cedars and oaks too.

what kind of wood?

looks to be a conifer from the errant pine needles. can you confirm?

No stalk.

They don’t have any stalk at all, as far as I remember, and rather frimly attached. I also have another observation http://mushroomobserver.org/60984?q=3TCb (sorry, don’t know how to copy within MO) that I believe is the same mushroom.

if you have

more details… I would guess the genus Lachnellula if it has a short or almost no stalk.
