Panaeolus cambodgeniensis Goliaths ?

Is that what you are calling them?
The only pans named Goliaths are the Panaeolus (Copelandia) cyanescens : Thailand, Suphanburi Goliaths sold by Sporeworks and are the original trade name owned by Sporeworks


Errrr..... This confusion is my fault, but I do appreciate the defense. I've recently reexamined the Goliath and other specimens and reclassified them as indeed Panaeolus cambodgeniensis. I've submitted an amended description to Sporeworks but it has yet to be added (soon I hope). I am still trying to get accurate classifications down, but there is a lot of conflicting information on how to separate these closely related species. It doesn't help that the main Panaeolus monographs are in French and German. But I have made some significant progress recently and can justify the reclassifications.

To make matters a bit more confusing (and embarrassing to me) the Sandose "tropicalis" is also P. cambodgeniensis. Also, there is a good chance that the Texas pan that is circulating is a true P. tropicalis, although I need to regrow that to confirm. I foolishly didn't save any specimens.

Here is an exclusive preview of part of the sporeworks site update for Panaeolus that should help explain some of the taxonomic problems I've encountered.

Species summary

Panaeolus cyanescens: The most common (in the wild) species, pallid pins or only slightly pigmented that soon fade with maturity, large spores (majority over 12 microns).

Panaeolus cambodginiensis: The second most common species, very dark chocolate to olive pins, small spores (majority under 12 microns), sometimes produces sclerotia-like bodies. This species seems to be overly represented in circulated strains compared to purely wild collections.

Panaeolus tropicalis: rare, pallid pins, small spores (like P. cambodginiensis). This is the most confused documented species. Stamets (1996) indicates that it is an exclusively two spored species (two spores per basidium) which is incorrect according to all other sources. Gerhardt's (1996) key to the Copelandia implies that it’s a darkly pigmented species which conflicts with the actual description in the same document (which is based on Ola’h’s (1969) original description). Ola’h (1969) gives great importance to the internally granulated transparent spores of P. tropicalis, but Gerhardt’s (1996) examination of Ola’h’s herbarium deposits notes only opaque spores. Gerhardt instead gives importance to the form of the pleurocystidia, which are distinctly cone-shaped compared to other Copelandia.

Wow, beautiful mushrooms you have there Dr. H! :cool: Have they been evaluated by anyone yet? I bet they are some bad mofo's ;) Nicely done.

Excellent info Workman, thanks.

Nice to know Workman, because I was going by your data from sporeworks.
Sorry Dr.H, my bad due to what workman stated, his site not updated.
Shroom ID can be tricky. They are the Goliaths, but reclassified. Looks like both of us were correct, just my ID was from old data.
I stand corrected.
Beautiful work.

Well hopefully I will still be able to get some pics up in here within the next week or two as the manure I have is almost colonized now.Not sure exactly what I am going to do with it,I am pretty much only setup for cubensis at the moment but did manage to get a new aquarium heater so may just make a small TIT FC for the spawn?What do you think I should do with the spawn I have this time around?I do want to redo that smiley face cup,I got a few mushrooms off of it last time but It was nothing to brag about,and not what I envisioned it too look like so I want to try it again and get a good pic.I have like 4L of spawn so to play with so...Any ideas of how I should go about fruiting this time around.

i'm soooo glad you "messed up" the title to this thread, cause the names, and classifications have been frustrating to me to sort out, glad to know i'm not the only one, and THANK YOU Workman for always working, man. great info, the goliath, cambodegenisis, and various other Panaeolus species just boggle me sometimes. but now light is shining, and by the way Doc. friggin beautiful pixs, i put them in my screensaver slide show. just beautiful to look at. thanks.
