Hi,

G. Bauer sent me photos of an unknown bryophilous discomycete which we have never seen before. We hope that you have an idea! Here is a description: On a mossy rock (granite), on Lophozia cf. ventricosa. Apothecia 0.5–1.5 mm, yellow orange with slightly lighter margin, underneath light yellow, hardly any stipe. Ascospores (11.5)13–15 x 3–3.5 µm, partly 1-septate. Asci 55–62 µm long, Melzer's/IKI+, with croziers. Paraphyses filiform, septate in the lower part, furcate. Hairs ± straight, smooth. Conspicuous feature: the apothecia sometimes change colour in tap water or aqua dest. and become ± pinkish, in KOH they always become immediately vinaceous.

Best wishes,
Gernot
