Dear Forum,On decorticated wood of Castanea,I foun
I found a couple collections of this small asco at 3100 meters under Abies religiosa at the Reserva de la biosfera de la Mariposa Monarca, El Rosario, Michoacan, Mexico. It was growing in tire tracks of a rarely used road, and also on road sides. It has no stipe, but as attached to the substrate in the middle of the underside. 3 - 8 mm diameter. Sometimes attached to organic matter. Under Abies religiosa.
Cheilymenia and Scutellinia have been suggested, any opinion on which name is more likely? Or another genus? I have not scoped it yet, but I do have a microscope. If I scope it, what should I look for?
Hi Alan,
I think nobody can reliably say anything without microscopical details. You should dry your collected ascomata in the air, maybe on a heating, and afterwards examine the dried specimens or give them to somebody who has a microscope.
Scutellinia does not seem very likely to me - and a lot of genera are possible. The only thing we know definitely is that it has carotinoid pigments that are very much distributed in Pezizales.
Regards from Lothar
This looks like Cheilymenia crucipila, but as Lothar said, microscopic data are required to help you.
