P. semilanceata look-alike

Good day,
I found these in the field where I often find P. semilanceata.
Pictures:
   
Initially, I thought these are just oddly shaped P. semilanceata. They were too different, however, from others I found in the same field. A comparison:

 
 
2 hours later (using flash):
  
Then, I thought they might actually be P. strictipes. But quick microscopy shows that they are not. Spores are huge - 17-20 x 9 - 10 um (one piece of micrometer = 0.99 um):

Side-view shots:
   
Compare to P. semilanceata spores (12-14 x 6-8 um):
 
Cheilocystidia also does not match P. strictipes:
          
Compare to P. semilanceata cystidia:
    
They were quite dry; thus, I couldn't check if there was any separable pellicle. No bluing so far.
Any ideas?
Let me know if you need further details (I would be happy to make a detailed, standard description).

Looks to me like you have Protostropharia semiglobata
-------------------- Favorite quote: I want to know if they are active and magic or not. And if they are not active, can i pick them before they are active and then they will become active or do they have to grow till they activate?

Ellipsoid large spores suggests that as well...

Thanks for your replies (and apologies for being so slow to reply myself).
I believe you're right - they're most likely Protostropharia semiglobata. I'm surprised how similar (macroscopically) they can be to P. semilanceata under dry conditions. Have a look at these, for example:
5 and 6 from the left in the lower part:

Or 1, 2, and 7 from the left in the lower part here:

They look rather similar to Protostropharia semiglobata in the first picture of the original message (especially to those on the right hand side). I'm quite sure these are P. semilanceata (though I cannot rule out P. strictipes) as they bruise blue. Have a look:
   
Compare to dried specimens of semiglobata:

Side by side with dried P. semilanceata (right hand side):

I guess people have eaten semiglobata thinking they eat semilanceata. For an inexperienced eye, distinguishing the two species could be rather difficult under dry conditions (though, now I see that semiglobata have somewhat deccurent attachment and non-flexuose stalk). Good that they're not deadly poisonous.

Did you scope the specimens in question?

Yes, they are P. semilanceata (I think I said so in my previous message). All three bruise blue - first two pictures of dried specimens in my previous message depict the same 1, 2, and 7 fruits you refer to.
It gets somewhat confusing with multiple pictures and multiple specimens (perhaps it would be easier if I numbered them):)
