These apothecia were growing on decaying leaves of Polytrichastrum formosusm. The apothecia are scattered, shortly stipitate. Disc brownish, briefly cupulate, later applanate or pulvinate, up to 1 mm in diameter. Excipulum minutely downy, whitish. Margin glabrous.
Asci 62-100 x 10-14, 8-spored, without croziers, the apical pore IKI b of the Calycina-type. Paraphyses with no refractive VBs, covered by a crystalline (?) yellowish-brown matter that stains in Crb. Ectal excipulum with hyaline textura prismatica-angularis-subglobulosa. Medullary excipulum of textura intricata, the hyphae covered by the same yellowish-brown matter of the paraphyses.
I feel this fungus is the same described by Spooner [Kew Bulletin 38(4):563-565 (1984)] under the name Bryoscyphus turbinatus (Fuckel) Spooner, but, in my opinion, the fungus is absolutely not a Bryoscyphus, because the lack of refractive VBs at the paraphyses and and the cellules of the ectal excipulum, and the apical pore of the Calycina-type. Furthermore the crystalline matter covering the paraphyses and the hyphae of the medullary excipulum is not present in the genus Bryoscyphus.
What genus is appropiate for this fungus? I don't know, but in my opinion not Bryoscyphus.
Probably the study of dry material did not allow a suitable study.
What do you think?
