48. Mature cap rounded-cylindrical, more or less like a shaggy mane cap; volva absent. 49

49. Mushroom 15-45 cm high at maturity; stem 1.5-3 cm thick at apex; in North America known from southern California, southern Arizona, and southern Texas (and probably to be expected in Mexico); spores mostly under 10 µ long, with a distinct pore. Podaxis longii

49. Mushroom smaller than above (under 20 cm high, with stem up to 1.5 cm thick at apex); distributed throughout western and southwestern North America; spores variously sized, with or without a distinct pore. 50

50. Most spores over 9 µ long, with a conspicuous pore.
Podaxis pistillaris
at MykoWeb

50. Most spores under 7.5 µ long, with an inconspicuous pore or without an apparent pore. 51

51. Spores ellipsoid, generally under 7 µ long; gleba olive brown to yellowish brown. Podaxis argentinus

51. Spores subglobose, generally longer than 7 µ long; gleba reddish brown. Podaxis microporus

What I meant by saying I’m beginner is to introduce my self and say to you as beginner I saw it Coprinus, what about other mycologists though.

I have a lot of specimens

Hi Debbie Viess, First of all I’m sorry. Of course you didn’t mean to insult. as you said nothing makes you do that. Sorry
Secondly and fortunately today ifound a lot of samples look likethis one grown on our university, more than 20 cm in height.I will make a cut and wait for sporing to studythe spores.

Thanks very much

next time …

cut one in half lengthwise. That should give you good information as to whether this is a normal gilled mushroom (Coprinus) or a secotioid (Podaxis).

Your second photo also looks like a Podaxis to me.

No insult meant Marwa … I don’t know you or your myco-abilities or access to a scope.

a new photo

would you please look at the new photo I upload?

Yes, much fatter than the photo

Yes, I found a lot of specimens those were fat, sometimes giant. I’m a beginner in mushrooms, but I saw it a bit different from Coprinus. Of course, I have access to microscope. however, the area is a bit far from me to collect another specimens. Thanks all
Thanks Christian (Christian Schwarz)

are we so sure that exact same species occurs …

from the NA deserts to Sudan? Sure, it’s similar … but the African species appear fatter at the apex.

If you have access to a microscope Marwa, check the spores … you can compare them to NA pistillaris spores here:

Podaxis will not deliquesce (dissolve) into black ink

False ink cap??

It looks like the coprinus comatus, it was grown in a green house. how can I differentiate between the two and confirm?
