yellow asco in sunflower table
Edit Szilvásy, 15-10-2017 21:54
Edit SzilvásyHi Forum,
My friend found this fungus.
It grows on a sandy soil of a sunflower table. The size 0,5-3 cm. The color is lemon-orange, the outer and inner surface have the same color. Young meat is flexible, later can be broken. It doesn't content milk. Spores lenght 16,2-19.1 x 9.5-10.8 mm. Hairs none, no colour change in iodine.
Thank you for help.

Re : yellow asco in sunflower table
Hello,
interesting find. Would you have any photo of the ascus base and of the margin?

Hello Viktorie,
There is  photo of the ascus base, but isn't the margin.
Thank you for attention.

Re : yellow asco in sunflower table
So we can exclude Geopyxis now, because it has rather distinct forked ascus base.  
Maybe Pseudaleuria? But it has hyaline to brownish hyphoid hairs. Or perhaps an overgrown Cheilymenia, which should have some superficial hairs as well.

Hi Viktorie,
My friend and I, we are amateurs. We do not have any practice to observe the small details. But we're trying :-) Now we know how important to observe hair. Thanks for the help.
