?See N+N+B Vol.3 pp.132-140 [as aggregate with L. carestiae]; H. Singer, G. Moreno && C. Illana 2001 'Nivicolous Myxomycetes from Tyrol (Austria). II. The genus Lamproderma' ÷sterr. Z. Pilzk. 10:25-42; G. Moreno et al 2002 'A study on nivicolous Myxomycetes. The genus Lamproderma I' Fungi non Delineati 19:1-66 - Sporocarps up to 2 mm total height, clustered or scattered. Sporotheca stalked, ovoid, 0.8-1.2 mm broad, 1-1.8 mm high. Peridium black, usually persistent, at least in the lower part which forms a cup. Stalk up to 0.5 mm, usually broad and triangular at the base, black. Columella cylindrical, occ. thickened at the apex, attaining up to 75% the height of the sporotheca, black, usually with membranous expansions in the upper part. Hypothallus dark brown at the centre, light brown at the margins, often confluent with adjacent hypothalli. Capillitium arising from the length of the columella with stout branches, rigid, dark brown to black, forming a dense net at the periphery, with many pointed paler free tips. Spore-mass black.
