there does appear to be white- to yellow-white rhizomorphs extending through a clump of soil into the air.

Obs. definately has columella,

but the base is not visible because of where the slice was made. I have the same problem with finding the base of Hymenogasters to slice through. A few mm another direction, and the base of columella may become obvious.

Thanks Danny,

For correcting the name, I still don’t know how the system works but knew the spelling was wrong.
There is an image in the Australasian Mycologist 23(1):1-26
The columella is quite distinct.

that C. walpolensis isn’t even pictured in that paper, and only occurs once throughout the text simply as a key choice, a key choice which cannot be arrived at without more info than this observation contains.

C. walpolensis…

… I’m not entirely convinced it’s that species with this set of data, that species is described as having a distinct truncate to percurrent columella tapering from the base to the apex and a bulbous base protruding up to 3mm below the peridium and with conspicuous white basal mycelium, I’d like to see some data regarding spores also.

I’ll try to give an answer, of sorts.

Octaviania, Descomyces, & Gautieria are previous constructs, generally not from Australia, and without DNA analysis to back them up. Recently at least 8 species of hypogeous Cortinarius have been described in http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2890163/. Based on the key provided, this may be Cortinarius waldpolensis. While I admit a pleasant-smelling Cortinarius sounds quite unusual, we still don’t have a specific dispersal mechanism for this species.

Just found this website:

has this to say about hypogeous Australian fungi: “The truffle-forming fungi of Australia, although poorly known, are highly endemic and extraordinarily diverse, with some 300 species described and another estimated 800-1200 yet to be discovered.”

This may well be a species and genus novum.

All the proposals

have a negtive confidence level, this is silly…

Can someone explain what is wrong with Octaviania, Descomyces, & Gautieria? Until you guys want to stop nuking ever proposal without much explanation I think Karode’s suggestion of Fungi is most appropriate…

By: Danny Newman (myxomop)
2014-09-15 11:21:36 PDT (-0700)

seeing the disagreement that this is an angiocarpous fungus…

maybe Agaricales s.s.
By: Danny Newman (myxomop)
2014-09-11 16:27:08 PDT (-0700)

but not a gilled mushroom, to which Agaricales sensu lato refers.

i guess…
By: Richard Kneal (bloodworm)
2014-08-22 14:45:09 PDT (-0700)

i can buy that.
however, on the other hand…this is definitely an Agaricales. ;)

By: Danny Newman (myxomop)
2014-08-22 12:08:28 PDT (-0700)

the sensu lato part of the name refers to the way in which Hymenogastrales used to be used. it’s a denoter of body form, nothing more.

I would also suspect this is a secotioid cort, from that gleba color.

Does Fungimap show photos online?

Trappe and Todd Elliot collected a lot of secotioid fungi in OZ … perhaps run this by one of them?

it was the first comment I made.

I could see
By: Emma Harrower (eharrower)
2014-08-14 21:01:22 PDT (-0700)

the color being called reddish-brown (or foxy brown? or bright brown?). I would not call it red. From what I’ve seen (looking at images of gasteroid fungi today), the gleba can go through a range of colors while the sporocarp matures. This color does not seem unusual to me. I agree with Daniel’s statement that it may require microscopy to figure out what genus it belongs to.

By: Daniel B. Wheeler (Tuberale)
2014-08-14 20:36:01 PDT (-0700)

Yes, I did.

There is no microscopy here. As noted earlier, microscopy is the major means of changing what was called Hymenogasters into four different genus. I prefer not to project what I may think onto this collection.

You would not call the gleba “red”? What color would you call it? Copper-red? Cinnamon-red? Cinnamon seems too tame a color to my eyes, and suggests shades of brown within it.

bruising was observed. Cut flesh remained the same as it was before cutting.

Colour of the pictures is fairly accurate as well.

The gleba of the cut one pictured once dried has darkened to a darker Brown, milk chocolate colour. Previously it was cinnamon Brown.

By: Richard Kneal (bloodworm)
2014-08-14 11:33:08 PDT (-0700)

did you read the paper I referenced?

if not:

I wouldn’t call that “red.”
I think cinnamon might be a better way to describe the color.
which is how it is described in the publication.

everything seems like a pretty good fit…
except, for that purple coloration…
which, I agree, may point to Cortinariod.

although, a lot of the photos I am seeing seem to have that same “hue” to them…

True, but
By: Daniel B. Wheeler (Tuberale)

all described species have differently-colored gleba. None has a red gleba.

That’s one reason I suggested Michael Castellano comment, because of his experience with Australian fungi. Teresa Label might also be a good source of information here. Dr. Trappe is currently in Australia as well.

I understand your believe these are Cortinariod. They do seem to be similar. But Australia has many fungi, few of which have been described in science to date. Most (all?) of the described Cortinariod species are Hymenogastrales, and have gray, gray-green, or blackish glebas.

I remember in 1993 Dr. James Trappe took many of his graduate students (including Michael Casteallano) to Australia for a 3-week collecting forage on the NE Australian rain forest. They returned with examples of some 300 different sequestrate fungi, including “truffles” which were found growing on tree trunks 30 meters high. Australian fungi must be taken as they are, not how we envision they should be.

Descomyces occurs in Australia
By: Emma Harrower (eharrower)
2014-08-14 10:25:11 PDT (-0700)

This paper describes three species. As far as I can tell, they all have white basal mycelium. The key to the sequestrate taxa in this paper uses spore morphology as a starting point for identification.

2014-08-14 04:58:04 PDT (-0700)

any known Descomyces or Descolea from Australia. Would like Michael Castellano to comment on this. He might have an opinion as to what it could be.

Was there any blueing or other staining to the peridium
By: Daniel B. Wheeler (Tuberale)
2014-08-14 04:42:51 PDT (-0700)

after cutting, karode13?

This does not appear to mach Octaviana. Would need to see microscopy for certain, but gleba doesn’t match any known Australian species.

By: Daniel B. Wheeler (Tuberale)
2014-08-13 05:37:28 PDT (-0700)

is something like mycorrhizal host, Richard. It’s hard to note what is important to a final species identification. It wasn’t that long ago that mycorrhizal associates were considered “unlikely to provide any semblance of an id.”

With unknown species, it’s hard to determine what will be important, and what will not. For example, the mature odor of Truncocolumella citrina comes to mind. Mature specimens auto-digest, like Coprinus. A mature T.c. without columella still present might be considered a fragrant pile of liquid poop that smells of licorice, inside a fibrous yellow peridium baggy.

You are correct that the odor is still not be as good as microscopy. Especially an SEM for those who demand excellence in the field. SEMs are heavy and bulky. SEMs hardly fit a pocket for ease of transport. Those extension cords are killer too.

One of the Australian mycologists that post here see it and can give an opinion. Otherwise I’m happy to send it out for someone to sequence.

By: Richard Kneal (bloodworm)
2014-08-12 21:52:56 PDT (-0700)

while it may be interesting and useful to note…
it is very unlikely to provide any semblance of an id.
microscopy and/or dna would be necessary.

Thanks Daniel!

Heh, will edit and correct spelling. :P

The columella-type structure information is handy too. Wasn’t quite sure of how to describe it. There is also a very squat, stipe-like appendage attached to the base of some.

Scent was mildly peachy and I suspect that’s why the local kangaroos were scratching them up.

Spores will hopefully be checked in the near future. Will update observation when this happens.

Well, you’re right, karode13!
By: Daniel B. Wheeler (Tuberale)
2014-08-12 20:51:00 PDT (-0700)

It is a sequestrate fungus (the spores are produced inside the locules: those interior tube-like structures). That just means you are unlikely to obtain a spore print from this.

It also has a columella-type structure. Columella is a vestigial stipe, sometimes located on the outside of the fungus, sometimes on the inside. This is on the inside.

The locules have an interesting arrangement, mostly aligned up and down the cut.

By “Pleasant, light fuity scent” I hope you meant to say “Pleasant, light fruity scent.” If so, you may want to change that comment or edit it. I do that all the time. Add some detail if possible. Fruity like: pear? peach? apple? cherry? quince? pineapple? mango? In other words, what kind of fruity odor do you think it has?
