Specimen available

Notes:
Please note that this may be the first example reported from USA (??).

Occasionally, over many years, I have seen what looked to “white” (bleached) columned stinkhorns. Today we found several again. But I thought they looked different in other ways other than color. The white ones have, for example, the dark, goopy, stinky stuff for most the length of the columns. And have little flaps along the columns to the hold the goop.
When I Googled “white” columned stinkhorn, I thought I found the answer – Blumenavia rhacodes.
But then I read that they don’t seem to grow here.
Wiki says: “Blumenavia is a genus of fungi in the family Phallaceae. The genus contains three species found in South America and Africa.”
The first 6 pictures were taken a Bluebonnet Swamp in Baton Rouge, LA on 1/8/19.
• The first 4 are of one specimen
• The next 2 are examples from another location
The 7th picture taken one later (1/9/19), is the same mushroom shown in the first 4 pictures and is now essentially pooped out. I dug out the base/eggshell/volva from the leaves and sticks. Note it is dark colored and the surface has a “cracked” look.
Looks like pictures on the internet of Blumenavia rhacodes to me ().
The 8th picture seems like it popped up overnight. About 4 to 6 feet from others in the 2nd group that was in the original post of yesterday. This picture was taken on 1/9/19.
Note the base/eggshell/volva is dark colored and the surface has a “cracked” look.
Looks like pictures on the internet of Blumenavia rhacodes to me (
).
The 9th & 10th pictures come from a third site.
Pic 9 looks like another example of Blumenavia rhacodes to me (??).
Pic 10 looks like an “egg” ready to hatch – maybe tomorrow? Taken 4 feet from Pic 9.

Questions and comments and corrections are welcome.

On 1/10/19 a LSU professor collected 7 samples and took them back to lab for dryout & sample prep. No results yet. More to come

Pictures I have on file as Columned stinkhorn (Clathrus columnatus) suggest
Blumenavia rhacodes is not brand new to Bluebonnet Swamp. I now think they are Blumenavia rhacodes:

- 1/1/2007 - 1/18/2012 - 1/6/2015

(Not sure if pictures can be posted with a comment?)

Thanks for notifying us of your find and leading us to the specimens. Both collections of specimens are dried. I did some microscopy this morning to confirm that this fits the description of Blumenavia rhacodes. The basidiospores are greenish and measure 1.3-1.7 × 3.5-4.4 micrometers, consistent with B. rhacodes. The breadth of the columns and yellowish color of the receptacle are also consistent. This will be the first record for the United States, but not North America. There are only two species currently recognized in the genus and this record will expand the distribution of B. rhacodes to the north by about 1200 miles (overland from Teocelo, Veracruz, Mexico). There have been other observations in Texas recently, but no specimens exist of those as far as I can tell. I will have this sequenced sometime in the next few months and will keep you posted on any progress.

I hope it turns out to be rhacodes.
