Overview | |
Plasmodium yellow. Sporocarps gregarious. Hypothallus small, discoid. Stalk 1.0-1.5 mm tall, translucent red-brown, darker towards the base due to included granules. Sporotheca prolate, 0.4-0.5 mm diam. x 0.8-1 mm high, occasionally globose and 0.4-0.5 mm diam., umbilicate at the base, sprinkled with clusters of white lime crystals. Peridium hyaline, dusted with white lime crystals. Dehiscence irregular. Columella usually yellow, sometimes whitish and capped with lime crystals, rugose, similar in shape to the sporotheca. Capillitium profuse, of thin, ramified and sometimes anastomosed threads which are nearly colourless or light brown and darker at the junctions. Spore-mass brown. Spores 6-7.5 µm diam., pale violet brown, irregularly verruculose, the wartlets usually in curved rows.
