After posting this observation and the other two – MO67168 and MO67169 – I became more interested in these fungi, specially because they look unusual compared with my past experience, and there was a proposal for the one in this observation to belong to the genus Bolbitius and even a suggestion of a particular species, B. psittacina . The fact is that all of them were found in the same place, although one developed in the soil (the one in MO67168 ) and the other two were growing in the wood of a fallen tree. On the other hand, their morphological characteristics seem to be different as the photos posted illustrate. However, now I think they all belong to the same genus – Bolbitius – although to (possibly) different species. Here are the steps supporting this conviction:
1 – I went back again to the place and I collect new specimens of mushrooms: the one considered in this observation and of the one considered in observation MO67168; (unfortunately I was not able to find a new specimen with the characteristics of MO67169);
2 – I observed under a microscope the spores of the specimens collected initially and the new ones, and compare them with those of the other two observations MO67168 and MO67169;
3 – For the specimens corresponding to this observation, I get the following results:
- Specimen collected in 05/05/2011 (Sp.1):
6.6 [8.3 ; 8.9] 10.6 × 4.4 [5.1 ; 5.4] 6.1
Q = 1.3 [1.6 ; 1.7] 1.9 ; N = 40 ; C = 95%
Me = 8.59 × 5.25 ; Qe = 1.64
- Specimen collected in 11/05/2011 (Sp.2):
7.2 [8.3 ; 8.7] 9.8 × 4.7 [5.2 ; 5.4] 5.9
Q = 1.4 [1.6 ; 1.6] 1.8 ; N = 42 ; C = 95%
Me = 8.52 × 5.31 ; Qe = 1.61

Concerning this observation, the similarity of the dimensions and the form of the spores indicates that they belong to the same species. I uploaded already some photos of the 2nd observation, of the microscopy and a photo comparing the spores of the three observations under consideration, this one and MO67168 and MO67169.
It seems to me that, as proposed by Christian, B. psittacina is a good candidate for the species of the specimens considered in this observation.

I will soon update the other two observations, with the data of the new specimens and of the microscopy.

Thanks, the tnihekr and Christian!

I’m working on this and related observations and I will update them soon.
