Hola a todos, este ejemplar no tendría más de 1mm de diámetro y 1mm de alto. Me ha llamado mucho la atención las células del estipite y su reacción al Melzer. No sé si tendréis alguna idea de que puede ser. Gracias.

Re : Sp
Did this fungus grow on sandy soil? It appears to be a Helotiaceae, perhaps a Bryoscyphus. Your spore table lacks a scale, did you measure them?

Whether or not the asci are inamyloid should bechecked with Lugol. The reaction you mention is due to the VBs in the cortical cells and paraphyses. VBs often react with iodine.

Re : Sp
Hola Zotto, crecía en zona arenosa, si tengo medidas, en cuanto a la reacción a melzer de las ascas son las dos últimas fotos, no se aprecia bien, pero es la foto que tengo.medidas
(7) 7.8 - 9.7 (10.3) × (3,4) 3,6 - 4,1 (4,4) µm
Q = (1,9) 2 - 2,5 (2,7) ; N = 47
Me = 8,7 × 3,9 µm; qe = 2,2

Re : Sp
o.k., below 10 µm.

In the worst case the ascus apex was hemiamyloid, a term which you perhaps heard of. Using Melzer instead of Lugol results in a negative reaction, unless you have mounted the preparation before in KOH and the washed with water.

A symbiotic association with the bryophyte could be possible.

Ok, muchas gracias Zotto lo tendré en cuenta, saludos
