Observation 7497: Boletellus emodensis (Berk.) Singer

I have an unidentified fungi.(Australian) The specimen was photographed on a live tree trunk between the trunk and breakaway bark. They (the fungi),were situated on the southern side (shaded) of the trunk about 5 feet above ground. They were in a group in various stages of growth. There were also some sacs of translucent liquid either on or between the fungi. There was no spore reading taken, no obvious aroma and the specimens were not disturbed.
The colour is accurate and photo was taken in natural light. The position of the fungi was between two tree trunks and therefore created a problem in photographing them on the correct plane. The photo’s were taken after torrential rain lasting a week. (10inches + )
One image although unsharp depicts the glutonous sac . The other image is sharp and unaltered.
This is the first time I have used this site and was referred by Clive Shirley, (Hidden Forest Fungi) N.Z. I have sent emails to several mycologists and Fungi sites without success. If you can help ID or provide an alternative referral address I would be most appreciative. I have an alternate email address, iedodd@bigpond.com. Many Thanks, (KK)
Today the 16th December 08 I revisited the site where the original specimen was found, photographed and sent away for dna testing. BEHOLD, a singular and similar NEW specimen in a more advanced stage of maturity was found. I am quite certain that this is the same species as the original ones from about 12 months ago. The physical shape has not changed greatly.
I have taken extra images in as many aspects as was possible and there are some distinguishing effects that may help in the identification. (All images were taken with natural light on long exposures.) These effects are reasonably clear in the images.
The speciman was not removed or touched in the hope that I can get back and observe if the cap has opened. The position of this new fungi is in the identical crevice, where the original ones were found. I would say that the new specimen was approximately 3.5 cm in length. I did notice also in one of the images that there appears to be some hairy growth on the stem that has broken away from the stem. The texture break on the stem below the cap did not extend the full circle of the stem as can be seen from some of the images taken from the opposite side. (I am not sure why this has occured.)
The original stems were white and the tops stawberry red. The more mature (new) specimen displays what I would accept as happening in a more mature specimen. The tree trunk is dead, and is of the euclyptus family, and stands about 20feet tall. The centre has burnt out to some degree which is fairly common in this species. From the growing shape now prevailing, I think that Tom Volk is probably close in saying that it could be a Boletus.
Final images and additional notes.
Observation 34119…to 34125 inclusive.
This was what I was presented with on arrival at the site of the specimen I have
been obseving. Unfortunately the time between the last group of images and these images was longer than I had hoped. The Cap was fully grown and sadly the specimen had begun to deteriorate. I have salvaged as much information as was possible. I must admit I was dissapointed in seeing this specimen in its final stage of life. (access to this area is difficult.)
Before removing the fungi, I took several shots to show the natural habitat and the state of the fungi.
The base of the stem appeared to be wedged securely in the crevase of the trunk. When removed, the underside of the cap was on one side severely effected by age.
At this point I decided that a spore count would not be creditable and so none was taken.
The stem at the base was as can be seen, to be wedge shaped. The texture was dry and woody. I have also bisected the complete specimen and it can be seen that the pink is still showing in some areas. There also appears to be some dicolouration in the stem near the cap, & I am not sure if this was natural, or caused by bruising during bisection.
The cap has easily discernable protrudences.
I also broke a small section of the stem off at the base of the stem.
It clearly shows the pink colouring at the outer edges of the stem. Apart from the deteriorating mushroom odour, there has not been any identificable aroma from the specimen each time I checked it . (1st, 2nd & 3rd obs group.) I did not keep the specimen. I do have some small doubts as to whether the original specimen (which has been sent to America for DNA testing) is the same as the second specimen that has been recorded in the same location on the tree trunk.
Only the DNA will prove this is hope. The original {1st images} were in a group. This obs was from the 16th December onwards and the specimen was a single specimen.

These are really amazing little Boletes!!

New images added fom 16-04-2009 shoot

The last three images were taken at the same site as all the previous images. I have used my thumb in the last image to provide a reference for fungi size. I still have not received the DNA results from the U.S., but will follow it up and see what the position is.
The images in reference are 41412/13/14

Reddish bolete

Boletellus emodensis (as seen on Dr. Halling’s site) reminds me of Suillus pictus, which I find lots of here in the eastern US (cuticle/veil overhanging cap margin, large greenish tubes, cap cuticle breaking into reddish scales). This is virtually always seen as a terrestrial mushroom. But last summer I found a few specimens growing from what appeared to be the base of a living oak tree (with White Pine in the vicinity).

Boletellus emodensis updated images 34119 to 34125

This group of final images were recorded on the 2nd of Jan 2009. The update notes are at the bottom of the original obs notes. KK

Boletellus emodensis
Some Japanese sites call Boletellus emodensis “Boletus chrysanthemum” but the pore size and pattern looks different to what is called Boletellus emodensis is Australia. The Japanese regard their version as edible.

This very shaggy fungus appears either solitary or in twos on dead wood the upper, drier parts of Barrington Tops National Park. It doesn’t seem to like the more humid rainforest conditions of the lowlands. It is very common at certain times of the year on dead causarina logs or stumps. Pores are yellow, and stain instantly blue-green on bruising.

According to Tony Young, several species are close to Boletus emodensis, but none has the minute cross striations on the spores. It is principally a Queensland fungus.

Boletus ananiceps is similar to Boletellus emodensis, but tends to be scaly and is wholly wine pink tinted.

Likely a Boletellus

I’ve seen Boletellus emodensis grow on tree trunks in No Qld. It’s not lignicolous, but the mycelium seems to to migrate there. Vagaries in moisture will alter how the pileus scales appear. Likewise, staining reactions will be hit or miss as well.

let them grow a bit and go back, Ian! I suspect these are still very young…

Very interesting specimens. They sure look like the buttons of a Tylopilus or at least some bolete. But we will probably never know for sure. :(

It would be great if you could post a photo of a cross section of this fungi, if you still have it. If not, then thanks for the detailed description.


Great conversation piece!

Several of us ended up talking about this observation at a recent meeting in Berkeley. They are pretty clearly primordia for a wood rotting basidio. The strongest suggestion was Tricholomopsis rutilans, but some thought it might well be a bolete of some sort. It’s great that you managed to get back to the site, but it looks like either it’s something even stranger or the primordia simply aborted.

Email contents to Katrina "Fungimap to Fungi Australia. (contains extra details)

Dear Katrina,
I have been given your contact information arising from my attempts to have an Australian (Mid North East Coast) Fungi Identified. (Dorothy Beebee (dbeebee@sonic.net))

It has been an exhausting experience to say the least. I have and still do, talk with several Mycologists, who are always very willing to be of help.

Unfortunately they do not reside in Australia. This does create a problem sometimes with native fungi that I photograph, and require identification..

I find that it is very difficult to get much help within our own country, except from fellow photographers, and semi professional people interested in identifying fungi, and a couple of Forestry Rangers with whom I have made friendships.

I have spoken by email with Clive Shirley on quite a few occasions, with a great deal of success, and also exchanged shots of interesting species. I also have his Hidden Forest Fungi booklet. He has been unable to help in this instance.

I have also been in touch with David Ellis, who wont be available till Monday the 19th.

Brian Perry and Professor Dennis Desjarden, (SanFrancisco University) have been able to identify species for me in the past, but I am still waiting for them to get back to me on this one.

This last Fungi I have had trouble identifying remains unidentified to this moment. ( I have visited every site imaginable and spent hours searching through thousands of images.)

When I first photographed it, I did not realise that it was going to be so hard to put a name to it. I did not disturb the fungi, although I did try to see if there was any distinctive aroma. I also took the photo in natural light.

Some of the fungi photographed did have small globules of some translucent liquid attached to them, and the red caps did appear to be moist and shiny in appearance. I did not try to see if the liquid was sticky.

The fungi were growing on the sheltered side of the tree, and there was a good range of varying growth in the observed fungi group. We had just received over 10inches of rain.

All had the same colour characteristics, although there were only two that I would describe as what I thought were full grown. (see images.)

After receiving several references from members of the Mushroom observers, who I do appreciate their efforts, I cannot get an identification that I agree with.
. ………..

In desperation I returned to the site, (a full days trip), and re-photographed the specimen. ( I really didn’t expect to see anything remaining)

I then removed one from its habitat, (between broken bark and tree trunk,) and split it in two halves (top to bottom.) I also, after checking it out for colour and any other noticeable effects, rubbed it between my fingers to see if there was any smell. There was some colour change inside the main body, slightly pinkish but nothing contrasty. (Mainly grey.)

The results were pretty bland. The fungi had lost its original red cap\ white body, and taken on a brownish appearance, and the texture of the cap and stem felt dried out and was in my opinion the case.

The two remaining fungi that I described as being the largest were the only ones remaining when I returned. All the others had disappeared surprisingly!

The moisture content of the tree and its bark had changed considerably from the time of my first observation and photograph. ( Very much dryer)
The fungi were located at about head height, (5ft) {I’m a shorty}.
There was approximately three weeks between the first photo and the last today. 27/04/08 & 15/05/08

When I presented the first photo I did not give the fungi measurements. I will attach the original of two taken in the first instance, and then again today. Because of the position of the fungi, (between two trees,) the distance between lens plane and image are very very similar.


I normally shoot macro at 1:1 ratio. I have determined image size and distance from the lens, to be the same in all shots ,with resolution being the same overall in each image. This should provide a reasonable comparison in the loss of size in the second set (last lot _DSD1554/1555) of images.

From what has already been discussed, the impression I get is that the specimens are of a woody group. The Identification from the Mushroom observers points to this, but I do not agree with their naming. (Tricholomopsis rutilans) I have compared all the site images and nothing matches. The cap of the fungi is still intact as a ball and this definitely doesn’t match Tricholomopsis rutilans.

The fungi I believe has lost at least about a third of its original size, (probably due to dehydration). The fact that it is still similar in shape rather makes me feel inclined to the WOODY description, but this is where the identification then is open to debate I hope I haven’t bored you with the details of the description, but would really like to have the Fungi identified, and if this is not possible with you, maybe you could fwd my information on to someone you think can help me out of my misery.

I have kept one specimen in a sealed bag, in the fridge, and will only be too happy to make it available for identification if the need be.

Many Thanks & Appreciation,
Ian Dodd (KK) iedodd@bigpond.com

Could be a Tricholomopsis rutilans
By: Debbie Viess (amanitarita)
2008-05-14 13:31:44 CDT (-0400)

They do occur in Australia, they’re woodrotters, and they do have the densely hairy, rose-colored caps. I couldn’t find any other good photos of primordia, but Kuo has a photo on his T. rutilans page that is a fairly close match:

If it is this mushroom, it should have yellow context and gills. Go back and solve this mystery for us all, Ian!!!

Tricholomopsis sp.
By: Dimitar Bojantchev (dimitar)

Looks like some kind of Tricholomopsis. Probably an aborted form of Tricholomopsis rutilans. If sqeezed by the bark and trunk…

Referral to Australian mycologists
By: Dorothy Beebee (dbeebee)
2008-05-14 11:36:30 CDT (-0400)

Have you contacted the folks who are involved with the “Fungimap to Australian Fungi”? Try contacting Katrina Syme ( syme@westnet.com.au ) in W.A. for a referral.As a botanical illustrator, she has been actively working on the project for a number of years, and may be able to give you the names of some mycologists to help you. I remember that mycologist Richard Robinson was immensely helpful when we had our International Fungi & Fibre Symposium in Denmark, W.A. several years ago.

Amazing color and texture on that rose-pink cap! I’m with Nathan…without a mature specimen (and maybe even then!) an ID is probably hopeless. Way too fluff-textured on that cap to be a Calostoma, altho the pink color works. ;)
Not sure what your glutinous sacs indicate, and really couldn’t see any detail in that blurry photo. Go back and reshoot (and collect and dry) if you can.

How big were they, anyway?

Cool fungus!
By: Nathan Wilson (nathan)
2008-05-14 00:09:43 CDT (-0400)

I would guess it’s a Basidiomycete, but that’s not saying much and I’m not even sure it’s true. They are definitely young, so it would be great to see how they develop over time if you get a chance to return to spot over the next few days. I’ve never seen anything quite like it, but as a wild guess it might be related to the genus Calostoma.

I was going to recommend that you ask Clive Shirley until I read that he is the one who sent you here.
