Is such guttulation normal for Sarcoscypha coccinea?
Yatsiuk Iryna, 21-03-2013 12:44
Yatsiuk IrynaHello, dear friends

Here, in the East of Ukraine I have found only Sarcoscypha austriaca (with characteristic germinating spores and quite large guttules), until this year. In this year the first collected Sarcoscypha is probably coccinea. But I see also quite large guttules in some living spores of that specimen. Is it normal for S.coccinea? 
The first 2 photos show spores of Sarcoscypha cf. coccinea, the third - S. austriaca, for comparison. 
What would you say?
With best regards,
Irina

Re : Is such guttulation normal for Sarcoscypha coccinea?
Hi Irina

Soem of the spores you show us are in the good state, i.e. mature: in the middle photo those with a pale reddish interior below the image centre are mature, and in the left photo the single spore right of the centre.

Those  spores with guttules in the middle are immature. This is typical: when the spores are 2-nucleate (perhaps still also when 4-8-nucleate) the oil drops are scattered  throughout the spore, but at maturity the finally 32 nuclei accumulate in the centre and the LBs near the ends.

I see I should show this maturation process on my website. Here is my drawing for the three species.

Thank you, Zotto, now it is very clear to me. Most of the coccinea's spores were mature with small guttules such as you pointed on my photos, but I treated them as dead and tried to photography immature ones! :)
Thank you once more,
Irina
