Peziza on sand
Marja Pennanen, 08-10-2012 11:02
Hello forum,

I was picking mushrooms and when returning noticed these on the way.
I did not see them on the way to woods, so they must have grown while I was there ;)

These did not reach 2 cm width.
The spores are about 14-20x 8-10- and with some kind of ornamentation.
The asci are about 250-300x 11-12 and paraphyses (width about 6) are not longer than asci.

Once again Nordic Macromycetes 1 did not help me to get a determination, which I could be satisfied.

Re : Peziza on sand
Hello Marja and forum,

in my opinión it is a species in the P. badia group, due to the dark tones and  brownish spores with tendency to be biguttulate. The asci should be unrestrictedly amyloid in Melzer.


It would be helpful to have more details about the spore ornamentation (reticulate, warty, etc.) and to check if the ascoma bleeds bluish juice when cut with a razor blade in the hymenium.


Cheers,


Ibai.

Re : Peziza on sand
Hi Ibai,

Peziza badia as I know is bigger, often in groups and grows much ealier, in summer. Now it is autumn here and this is much smaller and grows separately.
P. badia is a group species?

When cut, practicly no juice was bleeding.

I'm a bit busy now, but will try to get a better view to the ornamentation later.

Ps: there were 1-3 guttules in the spores and sometimes some smaller, too

Re : Peziza on sand
I think that may be Peziza boltonii Quélet [Bull. Soc. Bot. Fr. 25 (4): 290. 1879]. In a very common species in the sand areas of the Parco Regionale Migliarino San Rossore Massaciuccoli (Italy; Tuscany). In the attachment you have an article by Marchetti e Franchi with a full descriptions of this species.

Re : Peziza on sand

Hi again,

I meant that your Peziza belongs to a group of species in the neighbourhood of Peziza badia (P. depressa, P. badiofusca, P. badioconfusa, P. saniosa, etc..) sharing a dark brown colour, paraphyses with dark content, predominantly biguttulate spores of high ornamentation, a potential ectomycorrhizal habit and non-restricted amyloid reaction of the asci in Melzer´s, as discussed by Hansen et al. (Mol. Phyl. Evol. 36:1-23, as P. depressa-Ruhlandiella clade).

This was just a small clue... I guess we need to see the spore ornamentation to be certain about the species.


Cheers,


Ibai.

Re : Peziza on sand
Hi,

Thank you for your comments.

Wonders happen, the ornamentation appeared on a photo.

Hope this helps you to help me ;)

Marja

PS: I like very much P. boltonii determination. It is very close and would be new for Finland...
