The photos are actually of two collections. One made on May 25, and one on May 28th, but they came from the very same spot.

Here is a report about it with some quotes from Dennis Desjardin:

“Spongiforma squarepantsii, a new species of gasteroid bolete from Borneo,” was published online on May 10, 2011 in Mycologia

The cover photo is clearly the basis for the name.

This is Dennis’ scanning EM of the hymenium the warty spores with the prominent germ pore are mostly what is seen

Proposed Names

91% (2)
Recognized by sight: Orangish color, faint fruity odor, and of course the striking resemblance to cartoon character; the smell and color differ from S. thailandica, which has a coal tar odor and is grayish
Used references: This is a newly described species that is coming out in Mycologia.
Based on microscopic features: Almost identical to S. thailandica, only SEM differences in the spores were apparent
Based on chemical features: ITS sequence is very different (~10%) from only other described species

great article Tom and Dennis, and way to contact a majority of obsessive field mycologists/Citizen Scientists (is it just me, or is this term just a wee bit smarmy?): writing for M the J (that’s Mushrag to you) and posting to MO: over 3000 MO members and counting, many of whom are likely candidates for contributing to the North American Mycoflora Project.

Clever product placement, Tom! ;)

BTW, your link to the article won’t fully load (although I did read most of it already this past week). I tried from your lab website, too.

Thank God

Dennis and wrote a little ditty about the species in Mushroom the Journal. You can grab the article here:

This is the reference: Mushroom the Journal 107(28): 55-56, 58-59.

so juvenile, and yet so cool. ;)

plus, a real! live! bizarro fungus!

Mycologia is positively tame after this…unless that really IS the cover photo??! (I have only seen the online, preview version.)

super cool

I can’t believe this went unmentioned in the field course.

Is it possible to add a SEM image of the hymenophore which is supposed to look like a seafloor covered with tube sponges?
