Not. 131: 411. 1978. Figure 2j Holotype. SWEDEN, Uppland: Djuroe , Munkoe , 23 Sept. 1973, L.E. Kers 4264 (S!). Tulostoma niveum is a well-defined species with small and slender, whitish basidiomata with conically protruding mouth and distinctly membranous exoperidium. Molecular data suggest a close relationship with the new species T. eckbladii and T. giovanellae (Figure 1c). Habitat and distribution. Occurs among mosses on +/- calcareous boulders, flat rocks, or stone walls in semi-shaded localities. Recorded from Finland, Norway, Sweden, Switzerland, and the UK (Scotland). Not known from outside Europe. Specimens examined. NORWAY, Oslo: Malmoykalven , among mosses on calcareous cliffs, 13 Oct. 2006, A-E. Torkelsen, A. Wollan, A. Karlsson, J. Nilsson, J. Markussen, M.
