Geoglossum sp?

My name is Olga and I'm an amateur mycologist from Israel. Yesterday I found in a Pine forest an interesting ascomycete, that seems to be some Geoglossum species. The mushrooms grew on the ground together with Helvella leucomelaena, which is quite common in our Pine forests in Spring. The size of the fruiting bodies was about 3-3,5 cm high, 0,2-0,5 cm wide, the surface is matted, a bit rough, the color is dark brown-black, the stem area is brighter, brown-grey.
The spores 7-septated, long and narrow, about 90-102*7-8 µ, the asci 8-spored, as I could see, about 200-250*25-30 µ. The paraphyses look a bit strange to me, because their form is very irregular and I don't know, how to describe it exactly.
I looked for some information in the internet and found a description, that could fit, in a book "Mushrooms of Northeastern North America": "Spores 50-105*7-9, mostly 7-septate, upper cells of paraphyses enlarged and rounded to obvoid." - it is a descriprion of Geoglossum glabrum. But I am still not sure about the definition.
I'll be glad for your help.
Have a good day
Olga
PS: I searched other topics related to Geoglossum here on this Forum, and I think, that the microscopy of this species (which was identified as Geoglossum ccookenianum) looks similar: http://www.ascofrance.com/search_forum/9944
but in my case the spores are bigger in size.

Re : Geoglossum sp?
Thank you very much, Dirk! Yes, the paraphyses form on the picture is similar to what I have. I'll try to find more information about this species.
