Ethan CrensonHi all, A few weeks back a friend pointed out som
I found this ascomycete growing on a wooden pallet (I think it's conifera).
Size perithecia around 500um diameter.
I do not know what gender it belongs. Exarmidium morthieri???
Can you help?
a greeting
Susana
first I don't know this fungus and I have no clue about what it might be. Species of Exarmidium do not seem to fit well as to ascospores.
As always you should first make sure about the asci, uni- or bitunicate? It is not always easy to recognize and best seen on immature asci. The morphology of paraphyses or peudoparaphyses is likewise often informative.
It looks like asci have some apical apparatus. It does not appear amyloid on your photo but I suggest you try stains like Congo red or blue inks.
Buena suerte!
Jacques
I send some more pictures.
The content of peritecio is orange, but I do not appreciate colored spores or paraphyses.
Spores are mainly three septa, some with 2 and 4, even 5.
The asci I think are monotunicadas ??
IKI and KOH+IKI negative.
The paraphyses or pseudoparáfisis are divided septate and filiform.
Any ideas?
Gracias, saludos
Susana
Saludos.
Salvador.
Mirando tus imagenes creo que si que parece la misma especie.
Lo del color naranja del contenido tampoco es igual de intenso en todos los peritecios, de hecho en las primeras observaciones que hice no me di cuenta.
De momento no tengo ninguna información nueva. Si llego a algo ya te lo haré saber.
Saludos
Susana
