Hello!
Can someone help me,and tell if this is fungus?
Thank you!
cactus don't look so good...
Re: cactus don't look so good...
First of all: it's not a cactus but a Euphorbia (maybe horrida). Looks like some mechanical damage.
Re: cactus don't look so good...
That's what I thought.
There is no cactus you can't eat, but you just might regret it if you eat the wrong one.
Re: cactus don't look so good...
Hi,I agree it looks like it has been damaged.The white stuff is dried latex which the plant exudes when damaged.It looks like milk and is an irritant and poisonous so be careful and wash hands after handling it.
Re: cactus don't look so good...
Thank you guys for quick answer!!!
Re: cactus don't look so good...
Iann, in your opinion, what are "these"? Thank you!
Re: cactus don't look so good...
Looks like Euphorbia ferox to me.
Re: cactus don't look so good...
I agree with teo that it is a Euphorbia horrida,I have a few of them.
Re: cactus don't look so good...
I would not rule out a fungus, because the dark borders around the lesions look suspicious to me.
You can find out, if a fungus is involved, in most cases by examining the discolored areas with a high quality hand lens. If a fungus is present, either the primary pathogen or a secondary one (weak pathogen or saprophyte), you should be able to see tiny spherical or elongate slit-like structures and/or a web-like, fine webbing (mycelium).
If these structures are not present, then the best thing is to do is to keep an eye out for any changes, be it an increase of the present lesion sizes or additional lesions.
I do hope, that the problem was caused by a mechanical injury, the wounds are healed and the plant continues to thrive.
