No herbarium specimen

Notes: This fungi was in fact two specimens growing together on individual stipes but joined at substrate level. I separated the two in the final image.

Ian! That would be really good. The Boletellus you provided a while back is now in Brisbane. Thanks to you, we have a first record of B. dissliens from NSW. Good on ya.

Bart was the one who pointed me in the right direction re: Multifurca. The specimen I provided at that time was from Costa Rica, Multifurca furcata. Thanks!

Roy H Specimen

Roy, I will attempt to collect a specimen next time in the area at the same time of the year. I did think this was a bit different. One never knows.
I am going to try out a system of keeping and identifying specimens that means that if I do have an interesting find and a request for a specimen,I will be able to provide the dried specimen at a later date. Chow kk

Multifurca

Bart, I did notice the latex in some instances was tending to turn slightly green, when the light shone through it or it was in direct light.. Chow, kk

a latex-producing Multifurca

Hi, this is a very interesting find and no question about its identity (Multifurca) ! Multifurca is now know from SE USA and Central America, India, Thailand, China, New Caledonia and Australia. This is the second Multifurca producing milk when injured. Does the milk turn green ? I would be interested in having more details on ecology and host trees for this species. I have asked the specimen from the NY bot. garden on loan, but would be interested in more specimens for a complete analysis.

Okay Thanks

published in Fungal Diversity as I mentioned already. You can go to the journal’s website and download the PDF, I believe. Multifurca furcata also has a latex, but M. zonaria doesn’t.

where can i find the genetic Hypothesus ?

it looks a lot more like Lactarius then Russula to me…Hmmmm this is really interesting though

I forgot to mention that gene sequences support the generic hypothesis of Buyck & Hofstetter.

Wow

didn’t even know it existed!

Multifurca

is a recently described genus that is purported to bridge the gap between Russula and Lactarius. I have seen M. furcata in Costa Rica and M. zonaria in Thailand.

There are images of the Costa Rican M. furcata here: http://www.nybg.org/bsci/res/hall/furcatus.html. Sadly, the images don’t show the zonate context.

Ian: if you can get back to this locality, see if you can get some to dry for a voucher – I don’t recall the genus (or its species) as reported from Australia (yet). Pretty wild stuff!!
