EstimadosMi nombre es Pablo Sandoval y estudio macromycetes de Chile, entre ellos obviamente los ascomycetes. Y aunque conozco hace ya bastante tiempo este grandioso foro, recien ahora me he decidido a participar.
Ahora mi consulta es la siguiente: Hace algunos años encontre en la cordillera de Los Andes, al sur de Chile, algunos estromas desarrollandose sobre ramas vivas de Nothofagus pumilio (lenga), y la verdad nunca he podido averiguar de que se trata, las esporas me parece que tiene engrosamientos en la pared y me recuerdan a las de Scopinella solani. Si a alguien le resulta familiar esta especie y me pudiera orientar, se lo agradecería mucho.
Adjunto fotos, las macro estan en mm y las micro en um.
Saludos cordiales

Re : Scopinella? from Chile
Dear Pablo,
It is difficult to confirm your identification of Scopinella solani without some further information. How many spores are there in each ascus? It looks like two in your photo. Are the ascospores shorter than 7µm?
Some species of Scopinella, such as S. sphaerophila and S.gallicola are very host-specific mycoparasites while others, such as S. solani seem to be on dead plant material. Is it possible that the ones you find on Nothofagus are actually growing on another fungus? What are the round structures with the perithecia on them?

Re : Scopinella? from Chile
Gracias Dave por tu respuesta
Las esporas miden 8-9um de diametro y segun mis observaciones los ascos son 2-esporados.
Y la estructura redonda que se observa es parte del hongo, son estromas con muchos peritecios que se desarrollan sobre ramas vivas de N. pumilio.
Y no creo que se trate de Scopinella solani, solo que su morfología me recuerda el genero y esa especie.

Re : Scopinella? from Chile
Dear Pablo,
That is a very interesting species!
No species of Scopinella is known to be a plant parasite or to have a stroma. It seems very possible to me that the stroma is caused by another species of fungi. If so, then your species would be similar to S. sphaerophila, including the asci with two spores. But then, what is the host fungus?
Perhaps another person on this forum can comment on the stromata. I am not familiar with the fungi on Nothofagus and may have overlooked something obvious.

Re : Scopinella? from Chile
In the attachment You have the description of Scopinella solani by...David Malloch ! I known other three works about Scopinella:
(1)Malloch D. 1976. Scopinella sphaerophila. Fungi Canadenses 83 [I have the PDF]
(2) Stchigel A. M. et al. 2006. Two new ascomycetes from rainforest litter in Costa Rica. Mycologia 98 (5): 815-820 [I have the PDF]
(3) Tsuneda A, Hiratsuka Y. 1981. Scopinella gallicola, a new species from rust galls of Endocronartium harknesii on Pinus contorta. Can J Bot 59:1192–1195 [not in my library]
I have also the works by Léveille where the name Scopinella is published for the first time.
Ciao, Alessio

Re : Scopinella? from Chile
Muchas gracias a todos por sus respuestas
Y Creo es un poco complicada la especie, y tendré que observarla más al microscopio, pero la verdad nunca habia considerado la posibilidad de que lo que yo llamo estroma, fuese otro hongo... muy interesante.
Apenas tenga novedades las publicare.
Saludos
