Author's notes

Growing on old cow manure that I used as a topdressing on the vege bed over winter. Not a very distinctive species I'm afraid. The biggest caps were about 25mm across and a bit slimy.

Not sure about that Pam. We've had B. vitellinus come up in the grass near the house, not from manure, and the young fruiting bodies are yellow and very slimy: Fungus Bolbitius vitellinus (Bolbitius vitellinus) on 6 Dec 2017 and Fungus Bolbitius vitellinus (Bolbitius vitellinus) on 10 Jun 2008
These were only slightly viscid, and were that pale tan colour right from small, never yellow. I've also put a record of what I think is the same species growing in horse manure in Kosi NP on CNM recently. If you look in unidentified fungi there you'll find it - no-one has ventured to give it a name yet.

Hmm...fair comment. They looked yellow on my computer. Any chance of spores? Remove the identification.
   22 Jan 2019
Nope, no spores. Checked the vege bed and all the fungi are kaput, unsurprisingly after all the heat we've had. Maybe there'll be more up if we get another good dump of rain.

The only other thing I can think it's like is a species of Psilocybe. If you do a search on P. subaeruginosa you can see if it correlates to your species. Again a spore print - even just to get the idea of colour always helps.

Does the fact that it is emerging from cow poop have any bearing on the ID? There must be a limited number of things that do that. I have a photo of something that was ID'd by Tom May as Psilocybe subaeruginosa a few years back, and it doesn't look the same.

This genus is one of the so called 'dung fungi' though they do grow other substrates as well eg grass, wood chip, mulch, decaying wood, humus and moss. They are a much larger group than people realise and I suspect many of the Australian ones have not been identified. The thing is they have a visid cap (when moist) this can dry to be glossy, attached gills and dark purplish to black spores some species bruise green./blue though not all. They belong in the family Hymenogastraceae as do Deconica which I suspect that group of dark brown fungi you put up belong to. I'll make a note against them

OK, I've had a look at Psilocybe images on line and am still unconvinced, at least of it being P. subaeruginosa. I handled these things a bit and didn't notice any blue staining. I have some photos of more definite Psilocybe from our gully, growing on soil or wood that I don't seem to have put up yet, so I'll stick them up for comparison. They look different to this thing.

This is great to be expanding our knowledge. I agree re P. subaeruginosa as the ones I've seen here tend to 'blue' and have paler coloured stipes. Have you noticed though when looking through different references how you will be seeing a differences in images. Which makes me wonder if people see a photo and assume it's a species and put a name on it. The problem with fungi is that unless you look at the microcharacteristics it's easy to be slightly off. Except for very obvious spp. such as Aseroe rubra for eg.
   23 Jan 2019
Actually I notice I do have one of these previous Psilocybe sightings up already: Fungus Psilocybe sp. (Psilocybe sp.) on 30 Jun 2018 It is more conspicuously viscid than this thing. Oh yeah, on the references. Difficult with fungi when there are so many very similar ones and undescribed ones. You'd hope the books have their IDs right, but the internet is a minefield.

Have just been looking at the family Strophariaceae as some of the characteristics of this fungus and those brown ones seem to keep bring me back to this family. I now feel that an option might be Stropharia semiglobata. What do you think?
   24 Jan 2019
The Tassie fungus guide mentions a slimy stipe for S. semiglobata, which this didn't have. In fact if anything, the stipe looks hairy. And the photos of that species in Fuhrer show a very narrow cap on top of a very long stipe, not at all the proportions of this thing (and in fact rather like one of the things I put up last night as Psilocybe - sigh). Have a look at my Kosi NP sighting too, which I think is the same: https://canberra.naturemapr.org/Community/Sightings/Details/4184287

Thanks for that Jackie. From the images I've seen of the Protostropharia (sorry I had used the old name before) semiglobata none of them seem to have that very distinct wide umble as shown in your photo. So sorry looks like we have to wait till there are some spores available!
Is there anyone in the group near you that has a compound microscope that could be used to help with these identifications?
   24 Jan 2019
Yeah, Paul and Kerri put up fungi sightings with spores, so if I can store the spores somehow I could get them down to them to be photographed. Bit of a production though as they are not that close. How much magnification is needed?
Pam wrote:
   24 Jan 2019
Spores tend to dry out very quickly, unless on damp paper! They last well if protected. How many times have you seen a great spore print with nibble tracks through it from some hungry invertebrate. Magnification its going to depend on the species. I start low and increase to 60x, which is often OK. Otherwise I have to go to oil emersion at 100 x. Paul and Kerri should be able to give you good instructions.

I had another few of these pop up in the vege bed after more rain. Pretty sure they are the same. Spore print photo has been added, for what it is worth, but an actual spore photo might be in the too hard basket for now.

Well done with the spores Jackie. Subfamily Stropharioideae as described by Singer includes a genus Naematoloma in which he says "the stipe is never glutinous or viscid". I'm not fully up on the modern interpretation of this genus - though with spore colour, growing in dung and other charcteristics I still feel it belongs somewhere around here. Be careful with some photos as names may be assumed because the fungus 'looks like' what people think the genus/species looks like!

Just came across this thread. I’m happy to image anybody’s spores! I use a 100x water immersion objective with DIC optics. To make a reasonably permanent preparation for storage, add a small drop of water to the spore print, take a coverslip with a thin film of Vaseline around th edge and pop it on the spore print. Then arrange transport to Wonboyn!

Paul that is fabulous and very generous. Thank you. This may enable a number of our questions to be answered. I've found empty Berocca tubes with a circle of packing to stop the slide moving though not touching it's surface, provide a safe way of transporting slides.
   16 Feb 2019
Oh lord, another name change. Just googled Naematoloma and found lots of Hypholoma images, none of which really grabbed me as being the same as this thing. At some point we probably need to take a look through the fungi listed on ALCW and see how many of them need their names updated. I'll discuss this spore preservation caper with Paul - not sure I grasped the instructions yet. I've brought the similar fungus on horse poop I put up on CNM back to Heino Lepp's attention, so maybe we'll get some input from him on an ID.

Jackie spare yourself the terror of yet another name change - it's an addional genus name (I don't know if that's any better!) and not a genus I'm familiar with. They say one learns from ones students - well I'm well and truly learning from Naturewatchr
