I found this fungi on a Hedera leave. It isn't Trochila craterium or Hypoderma hederae, but then?
Asci: 93,7 - 114,7 µm. Ascospores: 20,6 - 24,8 x 5,2 - 6,1 µm.
Does any of you have a suggestion?
Thanks in advance!
Kind regards,
William

Re : asco on hedera leave
Las esporas me recuerdan a Lophiotrema, las esporas parecen un poco pequeñas, pero quizás Lophiotrema hederae = Lophiostoma angustilabrum.
Saludos cordiales.

Re : asco on hedera leave
Muchas gracias, Josep, for your reply.
Does Lopiotrema hederae occur on Hedera leaves?
There indeed seem to be some comparisons with the spores of Lopiotrema hederae and the spores in my pictures. However the spores in my pictures are more narrowed (or even septate?) than the spores of L. hederae are, which are only narrowed in the middle.
Or is that variable?

Re : asco on hedera leave
Hola William, no digo que tu hongo se trate de Lophiotrema hederae, por el apellido hederae doy por sentado que puede darse en Hedera, es solo que es lo más parecido que conozco, simplemente la morfología esporal me hace considerar Lophiotrema, aunque hasta ahora solo he estudiado el Lophiotrema rubi y en una sola ocasión. Es solo una sugerencia para iniciar un punto de partida.
Saludos cordiales.
