Glossary.Peziza succosa [ Ascomycota > Pezizales > Pezizaceae > Peziza . . . by Michael Kuo. Brownish cup fungi are not usually very easy to identify, but Peziza succosa distinguishes itself as soon as you handle it; it is filled with a juice that stains your fingers and the cup's surfaces bright yellow. Microscopic features include asci that turn blue in Melzer's reagent, and warty spores.In PVLG and Melzer's reagent (1:1 v/v) L1: An outer permanent rigid layer, smooth, pale yellow with a green tint (5-0-30-0), less than 1.0-1.2 µm thick and so tightly adherent to L2 that sometimes it is detectable only with superior optics under oil.
