Geoglossum

A group of these large 10cm pointed Geoglossum were in a local cemetery.The dark spores were mostly 7 septate with a few 3 4 or 5. From 66 - 83 long ave 76.5.
The Paraphyses were narrowly septate with swollen ends.
I was expecting G cookeanum but the spores are too big according to the details I have. The nearest I can find is G glabrum. It this a reasonable idea?
Thanks

Re : Geoglossum
Hello Malcolm,
this is in my opinion already G. cookeianum. The spores can already become long 80 µm, but always maximally only with 7 septa. The paraphyses on the photos are also rather typical. Geoglossum glabrum/sphagnophilum is a little species of wet locations (Sphagnum) with other paraphyses and evenly 7x septate spores.
In literature I have as a PDF:
BENKERT, D. (1976): Bemerkenswerte Ascomyceten der DDR. II. Die Gattungen Geoglossum und Trichoglossum in der DDR. Mykologisches Mitteilungsblatt 20 (3): 47-92. Halle.
OLSEN, SIGURD (1986): JORDTUNGER I NORGE. Agarica Vol. 7 Nr. 14 pp. 120-168.
ROOBEEK, C. F. (2009): Aardtongen in de duinen van Noord-Kennemerland. (2005 t/ m 2008). RO- rapo 09/10. Bergen, NH.
If I could send when required.
Greetings Peter.
Here still a photo of G. glabrum, unfortunately I havn't photo from G. cookeianum.

Re : Geoglossum
Thanks Peter I have two keys one giving 70 as a maximum length of spores and the other 80. Any extra information would be helpful so the PDF would be good.
Thanks

Hi Malcolm,
I have sent the PDF. Unfortunately BENKERT is faulty.

Hello, Peter,
if by "faulty" you mean "bad scan", my digital copy of Benkert's article looks ok. Sending to you both.
