Peridium evanescent above the calyculus except sometimes for a few small platelets. Cup obconical, rather shallow, plicate, papillose within. Stalk short, weak, concolorous. Capillitium a loose, very elastic net, scarcely attached to the calyculus, the tubules irregular, mostly 3-5 µm diam., often with numerous bulbous enlargements, marked with close-set, conspicuous spines, some reaching to 3 µm. Spore-mass dull crimson to reddish-brown. Spores pale yellowish, minutely spinulose, 7-9 µm diam. Plasmodium watery white, then rosy. |
