Zuzana Sochorová (Egertová)Hello,
this ascomycete grew in a city in Czechia, on soil, 215 m asl.
Apothecia orange, up to 1.5 mm in diameter, smooth, sessile, rounded or slightly irregular.
Spores 19.5-22.5 x 12-13.5 micrometers, ellipsoid, thick-walled, hyaline, ornamented with very fine warts, without guttules.
Asci 235-260 x 32-35 micrometers, biseriate, longly clavate, in Lugol entirely blue.
Paraphyses containing orange pigment, straight, quite densely septate, sometimes branched or with short lateral projections, 4-6 micrometers broad in the middle, 6.5-11.5 at the apex, terminal cell 23-43 micrometers long.
Excipulum t. globoso-angularis, with cells measuring 17-46 micrometers in the longer dimension.
I looked to literature at Kotlabaea, Cheilymenia, Boubovia and many others, but something was always wrong.
I will be glad for your opinions.
Thanks,
Zuzana

Re : Pyronemataceae
Hi Zuzana.
No hairs or hyphoid hairs on the outer surface?
Is it possible to see the spores in Cotton Blue?

Re : Pyronemataceae
I saw no hairs neither under stereomicroscope nor under normal microscope.
I will try to make photos in cotton blue on Monday (too tired now and away for the whole weekend). The warts are very little, visible only with 1000x magnification.

Re : Pyronemataceae

Hi Zuzana


Have you considered the genus Iodophanus?

Re : Iodophanus
Yes, that will be Iodophanus, thanks a lot!
I even already found the genus once, but now, growing on soil, it didn´t come to my mind.
It seems to fit well I. testaceus.
Here are photos of spores in cotton blue - ugly, but unfortunately I cannot do better.
Sorry for confusing topic name, already changed it.
Thank you, Zuzana

Re : Iodophanus
Good evening Zuzana

Actually think like Enrique ornamentation of the spores might suggest Iodophanus; by against the difference between I.carneus and I.testaceus is rather difficult, I am enclosing a paper that will be help you.

Michel.

Re : Iodophanus
Thank you, Michel.
Macroscopically this fungus growing on soil seems very different from Iodophanus I found on dung last year.
The non-coprophilous growth is OK for I. testaceus, but some other characters (size and colour of apothecia, size of spores), better fit I. carneus (at least according to the paper you provided).
Hopefully molecular methods will show whether these two species (?) are identical.
Best regards,
Zuzana
