Dimorphic asci?
Masanori Kutsuna, 22-07-2015 05:34

Hello,


Coccomyces dimorphus, described by Liang et al. (Mycosystema, 19(1), p. 3-6, 2000),
has two types of asci (normal cylindrical and lanceolate) in a ascocarp.
Does anyone know other discomycetes having such dimorphic asci?

Re : Dimorphic asci?
This needs a closer look. I rather suspect that this fungus has dimorphic paraphyses. Asci with such acute tips seem to me impossible for any spore discharge. Did you observe any amyloidity of the asci?

A close study of the acus base woud perhaps clarify. Asci and paraphyses emerge from two separate hyphal systems. Often the ascogenous system carries croziers, the paraphysogen never.

Another possibility would by intrahymenial parasitism by another ascomycete, but this seems to me rather unllikely.

If you have a a pdf of the Liang paper I would be happy to see it. You could, e.g., attach as a nouveau fichier.

Re : Dimorphic asci?
Thank you, Zotto

Both type asci inamyloid, and I can't see croziers.
In Liang's paper, paraphyses are "rare",  I can't observe thread-like paraphyses.
I send Liang's paper ?mainly in Chinese??by e-mail.
