Bonjour à tous/Hi to everyone I am passing along
Lamprospora
Lothar Krieglsteiner,
24-08-2010 16:54
in the Plitvicka jezera National park I found a small red discomycete I in the field considered to be a small Octospora or Lamprospora, only 3 apothecia in the vicinity of (cf.) Tortella tortuosa in a heathland on calcareous ground. The microscope said: a Lamprospora (spores round, with a distinct ornament of broken reticulate patterns)! But - the spores are too small for all species of the genus I became aware off. I measured 10-12 µm in living state, the spores are even smaller in my mount (that has become stained with cotton blue).Do I miss something? Or what else is the solution? (Unfortunately I have taken no macrofoto).
Regards, Lothar

Re:Lamprospora
Hi Lothar
Do you have a better microphoto showing the reticulate pattern?
Maybe it was as the one of my photos?
My species is Moravecia (Lamprospora) hvaleri. I find it next to cf Pleuridium acuminatum.
Associated to Tortella tortuosa (host moss) grows Lamprospora cailletii, but spores are bigger (14-15 without ornam. and 15-17 ornam. included) and the lipid body of the spore is 10-13 µm (Benkert´s data in his original description).
Cheers,
Raúl.

Re:Lamprospora
Dear Raul,
thank your very much for your posting. I have to have a closer look at the specimen. Can you tell me where Moravecia (Lamprospora) hvaleri is described, and who is the author, and what the spore dimensions are.
I cannot exclude Pleuridium acuminatum growing there (I know the moss, when it is fruiting).
Yours,
Lothar

Re:Lamprospora
Hi again Lothar,
The authorities are Dieter Benkert and Roy Kristiansen.
Moravecia hvaleri is described in Z. Mycol. 65 1999, p. 33-35: "Moravecia hvaleri und Kotlabaea trondii- zwei neue Pezizales-Arten aus Norwegen". Spore dimensions are 12-14 x 11-13 without ornamentation. I have found spores bigger (up to 15,5) but, as in all Octospora-Lamprospora, the variation from inmature to mature can be very high.
Recently, in 2007, Perry, Hansen & Pfister have found that Moravecia hvaleri is nested to the Lamprospora clade lineage in "A phylogenetic overview of the family Pyronemataceae (Ascomycota, Pezizales)".
Cheers,
Raúl.

Re:Lamprospora
Dear Raul,
thank you very much for the information. I am sure now that my collection cannot be Moravecia hvaleri, for the following reasons: My collection has
- clear and large oil drops in the spores
- spores perfectly globose (not broadly ellipsoid) and even smaller as given for M. hvaleri
- the ornamentation does not fit pefectly
- I did not notice Pleuridium
Especially the first reason is severe I think.
Anyway, M. hvaleri seems to be the taxon coming closest to my fungus by now.
Thanks a lot for your help!
