Buenas noches
En una reunión reciente, nos encontramos con que crecemos sobre las hojas de las plantas de Cruciata laevis (una Rubiaceae) es una posible pseudopeziza, pero no encuentro con nadie que encaje con esto. Al principio pensé en un Coccomyces. La característica más particular es que los asci son hemiamiloides. Todas las medidas en agua y en directo.
Apotecios en hojas verdes de la planta viva de Cruciata laevis, gregarios, semicerrados por medio de lacinias oscuras, pero que se abren en presencia de humedad, himenio color oliva, de (739) 740.1 - 816.6 (820.7) × (165.6) 167, 3-180,5 (183,3) m; N = 9; Yo = 783 × 173.3? M.
exc? Culo ectal con textura angular. Muy finoexcipulum medular con textura intricata, creo.
Asci Octospor, biseriato, cilíndrico, con croziers y hemiamiloides, de (66.4) 71.8 - 92.2 (95.2) × (5.3) 5.6 - 7.1 (8)? metro; N = 31; Yo = 83.8 × 6.4? M.
Paráfisis cilíndrica, no engrosada en el ápice, con pocas y pequeñas VBs.
Ascosporas subfusiformes y ligeramente naviculares, con LB abundantes y pequeñas, de (10,9) 11,6 - 13,3 (14,3) × (2,6) 2,8 - 3,26 (3,3)? M; Q = (3.4) 3.7 - 4.6 (4.8); N = 40; Yo = 12.5 × 3? METRO; Qe = 4.2.
La especie más cercana que encontré es Leptotrochila verrucosa, pero podría ser euamiloide y esporas con LB más grandes.
Gracias de antemano.

Hi Miguel-Amgel
yes, Leptotrochila is a good idea. I cannot say a species, but I wonder why you say hemiamyloid. Your photo shows blue rings while in L. verrucosa I noted the type rb.

Hi Zotto
I sent 2 pictures of the asci: IKI and KOH + IKI.
In the first one, with IKI, I view dirty-red in apical ring, isn`t it? In the second I view it blue.
Thank you.
Sorry the "spanish" languaje in my first post. The translator...

Oh, I am sorry, I downloaded some and overlooked the IKi photo as well as the legend.

Don't worry.
So, no idea?

I put it in my folder where I found nothing. No time to do any literature research.
In Wikipedia I find the name Cruciata laevipes, and I assume this is correct (?). In my database the genus does not occur at all.

Yes, sorry, Cruciata laevipes is the correct name for the host.
Ok, thanks, another unnamed asco.
