Rutstroemia maritima

I have this species from Parador de Mazagon, 15.01.2012 and 12.01.2013, on a small stem, perhaps Ammophila arenaria, 4-6 mm.
Spores (1000x, H2O, live)
(12.8) 14.0 - 16.8 (17.6) x (5.6) 6.0 - 6.8 (7.1) µm
Q = (1.9) 2.1 - 2.7 (2.8) ; N = 82
Me = 15.3 x 6.4 µm ; Qe = 2.4
I would like to confirm it is Rutstroemia maritima and to know nearest species.
Thank you.

Re : Rutstroemia maritima
Hi Miguel
to clarify this requires two details:
1. croziers
2. iodine reaction
I suspect Rutstroemia calopus, typical of Poaceae.

Hi Zotto
You are very, very fast. Your answer arrived before my last pictures, jejeje.
Croziers +
Euamyloid asci
Thanks

Re : Rutstroemia maritima
Nice photos! The croziers are clearly seen on the 2nd and 3rd of your pics, but not the striking protuberance at the separated asci (which is also present in paludosa) but with less contrast and when still attached. What I miss are crystals in the texture or on the surface. Maybe there are but rather small?
So it is calopus in my opinion. R. paludosa is on Cyperaceae and Juncaceae and has no croziers. R. maritima I do not understand. One collection which I studied named ?maritima had inamyloid asci, croziers, and grew on Ammophila. Maybe this was only an aberrant from of calopus. Dennis reports amyloid asci for maritima.

Re : Rutstroemia maritima
Are this the crystals? Very, very few.
Sorry, I don't understand "striking protuberance at the separated asci", I have more croziers pictures.
Yes, I saw your collection "R ? maritima HB6860 E, 10.II.01 from Spain", but I did not notice it is IKI -
So, don't exists R. maritima?
I forgot to said it was on dunes.
Best wishes.

Re : Rutstroemia maritima
Yes, now I see some crystals. And nice croziers. What I meant: The two ascus pics before the amyloid ascus apices show two +/- isolated asci with a prominent basal protuberance. This is not a proof for croziers, because it also occurs in paludosa.

Re : Rutstroemia maritima
Ok, now I understand it, I thought that big protuberance was a "extreme" crozier.
Any paper about R. calopus, R. paludosa, please? The only one I have "Le champignon du mois (12). Urs Roffler, 2002 SZP/BSM: 235-238" write Rutstroemia calopus (Fr.) Rehm = Rutstroemia paludosa (Cash & Davidson) Groves & Elliott.
Thanks.

Re : Rutstroemia maritima
Hi Miguel
The character of croziers is unreported in the literature as far as I know, it was a discovery of my own and was confirmed be rather many records from various people. From the substrate of the type collections I concluded for the two names: Groves & Elliott 1961 say Carex for paludosa, For calopus I do not remember, but someone should have treated it originally on Poaceae.

Somebody has the original description of R. calopus and R. paludosa?
See you.

Hi Miguel,
easy for paludosa: http://www.cybertruffle.org.uk/cyberliber/59350/0025/004/0271b.jpg?
calopus you will find here on P. 307: http://tiny.cc/d0h8sw?
Best regards

Re : Rutstroemia maritima
Yes, thanks Martin. The substrate given by Fries is quite dubious :-(
In my database I have some further possible names for this complex:
Helotium rubescens Crouan 1867
Rutstroemia henningsiana Ploettn. 1899
Ciboria blanda Svrcek 1958
Rutstroemia plana DM Hend. 1970
so anybody willing to check all these from type material? :-)

Hi Zotto,
If you possess the short publication of Henderson where Rutstroemia plana is described, you could send it to me! Thank you in advance.
The reference is
HENDERSON D.M. 1970 Notes on three British ascomycetes. Notes Roy. Bot. Gard. Edinb. 30 (1) : 203-205.
This collection seems accessible to this address

Re : Rutstroemia maritima
I regret I do not have. I see I was referring to the docu in Ellis & Ellis p. 542, on Eleocharis, which looked to me quite as R. calopus.
