Thamnidium elegans Link, Ges. Naturf. Freunde Berlin Mag. Neuesten Entdeck. Gestammten Naturk. 3:31. 1809.

 Description: Colonies developing moderately rapidly on PDA to ca. 9.0 cm in diam in 9 days at 24°C, turf sparse, colorless; fruiting heads gray. Sporophores erect, 7.5-20 μm in diam, arising directly from the substrate mycelium, constricted below sporangium, coenocytic at first, later irregularly septate, hyaline, simple or sympodially branched, with three types: 1) only sporangia formed terminally, 2) main axis and primary branches terminating in a sporangium and producing one or more lateral, dichotomous branchlets which bearing terminal sporangiola or 3) only fertile branchlets bearing sporangiola produced. Sporangia globose to subglobose, 50-99 μm in diam, hyaline, wall deliquescent; columellae obovoid, 27.5-45 × 22.5-35 μm, basal collar present. Lateral fertile branchlets arising from the sporophore singly, in pairs, or in verticels of three or more. Branchlets smooth, hyaline, three-dimensionally dichotomously branched four to eight times (mostly six), length and diam of the branches usually diminishing with each successive dichotomy. Spoangiola globose, 10.9-15 μm in diam, usually 4-5 spores, wall persistent, smooth, hyaline, deciduous; columellae hemispherical, 2.0-3.4 μm in diam, smooth. Sporangiospores ovoid to ellipsoid, 3-5 × 5-7.5 μm, hyaline. Zygospores not found. Heterothallic.
