Because all the specimens that I observed till now of the genus Tulostoma lived at the same place, though at different times, I presumed that they all belong to the same species; Maybe, that is not so …
Looking to the book of Sarasini “Gasteromiceti epigei” I noticed, as previously mentioned by Davide, the existence of three similar species: T. beccaianum, T. brumale and T. squamulosum. All of them have same type of exoperidium, membranous or submembranous, and the same type of stroma, intact and continuous.
T. brumale has as distinguished feature a dark circular ring around the ostiole. This is the case of the specimens in observation 161108 and observation 224027, where that dark circular ring is barely visible but present.
In the case of this observation I just uploaded a new set of photos with more specimens and at the end I also include a comparison of my observations of Tulostoma including this one (at the center). From all these we can see that there is no dark ring around the ostiole and that the stem is more squamulose and darker than in the other observations. In addition, the exoperidium is also a bit scrabose, which doesn’t fit the description of T. beccaianum, where the exoperidium is said to be very thin and delicate, sometimes with a flocculent-chalky appearance. Therefore, I think that this observation contains specimens of T. squamulosum.
Finally, many thanks to Davide, that claimed this from the beginning of his comments.

Got it!

it all look with a very dark stem.
do you have the sarasini?
there are very nice pictures and descriptions of something like a dozen Tulostoma species. i would do a micro,if i was in your shoes,just to be sure :)

This and my other two observations (#161108 and #224027) are from the same place, the only site were I found specimens of this genus. I don’t believe that there is more than one species involved (it will be too good!). As you can see the morphology is not uniform and at the same day there are specimen with and without a dark area near the stoma. So, I don’t believe that the existence or absence of a dark area is enough to determine the species, that may not be T. brumale, but is the same for all.

I’m sure this is not

Tulostoma brumale,since it doesn ’t have a dark area near the stoma.
i see also toom much bron in there. maybe beccarianum or squamosum.
