this question reminds me of the coastline paradox (From Wikipedia:) "The coastline paradox is the counterintuitive observation that the coastline of a landmass does not have a well-defined length. This results from the fractal curve-like properties of coastlines, i.e., the fact that a coastline typically has a fractal dimension (which in fact makes the notion of length inapplicable)." my take: the answer is constrained by the yard-stick you're using

using actively aerated compost tea seemed to enhance glaucus appearance and regenerate scarred and damaged epidermis, this is just an anecdote though

thanks

hey figman, I have some PM me :)

high CO2 is part of the reason why primordia formation is suppressed in this bag. excess CO2 isn't beneficial for fruiting. i wouldn't be surprised if that's why people use em. I'm only really interested in what species of mycelium is used in these bags out of curiosity.

Have you seen those bags of mycelium that are supposed to release CO2 into greenhouses etc.? (I'm not recommending this product, I'm using this pic to illustrate what I'm talking about) Does anyone know what species is used in these bags? Second hand info I've heard is that someone threw the contents on the bag in their garden and it fruited turkey tails. The producer of the pictured ones claims the mycelium they use was selected because it produces CO2 consistently and doesn't produce primordia. Could be helpful info, in my (limited) experience, Trametes doesn't like to form primordia invitro (aka without ample fresh air exchange). anyone tried using these?

Found this myceliated hairy caterpillar on a bushwalk. Since finding it a day ago, the mycelium grew from about 30% to full coverage. I'm guessing it's Beauveria / Cordyceps. I'm gonna put it in a humid takeaway container and see if any fruitbodies grow off it

yep, PM me

I'm probs gonna go

sounds like a good plan ! Plenty of agri chems (particularly pesticides) are endocrine disruptors, wouldn't be surprised if some phytohormes are too. That's a pretty wild anecdote though. What happened when the goofer dust wore off?

hey wc, I thought you were from NNSW, where cacti are legal ornamental plants . what law changes are you referring to? I'm in a warm area with no frost. My opinion - you can. It would be a good idea to keep the substrate from being watered and keep humidity low to prevent rot, while keeping it in enough light to minimise etioliation. I would go for a high high mineral substrate, then transplanting into richer mix in spring when it has a few roots. Have you considered using rooting hormone dust on the cut? I have seen some great and fast results from that.

Ye, could be P. papilionaceus, think I can see a toothlike frilly margin. can't hurt to focus the camera on the subject of the photo though lol

i'm not a fan of buried rootstocks It sounds like you will probably have to cut deeply or along a plane higher than the roots on the ario, because the pere will have grown up into the scion. I'd probably cut off the pere and wait until the ario was well calloused before placing it onto dry media. You're right that you can't give the ario anywhere near as much water as the pere or it will likely rot.

https://identify.plantnet.org works well

I am, thanks! in that study the same genus (Nicotiana) is used for both rootstock and scion. It would be interesting to see what would come from regeneration of cells at the graft junction between scion / rootstocks from different cactus genera.
