Bonjour tous
this is an area I feel rather ignorant about, rarely encountering this genus. This very dark Otidea was growing at the edge of a large garden, on soil amongst Cupressus litter, almost certainly Cupressus x leylandii. I was struck by the dark colour and initially assumed it was a Peziza. However closer examination showed it to be an Otidea, although a rather cupulate one.
Paraphyses were curved at the apex, and contained tiny granules. I noticed that a number of asci contained shrunken aborted spores which had gone brown (see photo) although whether this is of taxonomic importance I don't know. The medulla contained dark encrustations and also scattered crystals (see image, in polarised light). The "warts" on the ectal margin were made up of more dark encrustations. The ascospores measured 13.2-14.8 x 6.6-7.6µm. All photographs are of living material in water.
Reference to the Persoonia monograph has led me to Otidea bufonia, my only concern is the shape of the spores, which seem to differ from others I have seen of that species. Any comments would be welcome.
Cordaliement
Chris

Re : dark brown Otidea
Hola Chris, de acuerdo con la determinación, aunque yo le sigo llamando Otidea umbrina, al parecer hay diversidad de opiniones en cuanto a la denominación actual, segúm Mycobank debemos llamarla Otidea bufonia y según Index Fungorum Otidea cochleata, así que prefiero llamarla por su nombre anterior, es decir Otidea umbrina.
A esta la he estudiado hasta en cuatro ocasiones, dejo las medidas esporales de mis tres estudios anteriores, en mi último estudio aún tengo pendiente la medición de las esporas.´13,7;15,1 X 6,3;7,2, 14,4;15,2 x 6,2;6,6 y 15;16,8 X 6,6;8 micras.
Saludos cordiales.
