Hola a todos. Subo unas fotos de una Peziza que e
I found on a barkless branch of oak(quercus), lying on moist soil, stromata with perithecia with papillate ostioles.
Subilicum: woolly, rust-colored, sometimes covering two thirds of stromata, sometimes thinner
Stromata: 1.5mm globose, ostiole papillate, ectostromata: black and hard, endostromata: cream-colored woolly
Asci: cylindrical, 256 x 12.50 µm; ascal plug J + bright blue, Size, m = 15x7,8 µm
Spore: elliptical on one side flattened, completely surrounded by a slime layer round appendages, young with several large and small drops later, germ slit as long as the spore
Dimensions: 24.79 to 28.66 x 10.45 to 11.22 µm Qm = 2.47
Paraphyse: filiform, hyaline
Is it Rosellinia corticium, the spores are wider than mentioned in the key and the ascal plub is also very large?
Thanks in advance,
François Bartholomeeusen
Rosellinia corticium is a fairly variable species and I think your fungus fits well, tough the ascospores average broader. Often in Roselinia some apical plugs deviate in being more elongate than regular ones. I guess the one on your third photo is more representative.
Cheers,
Jacques
