Wraber, 1969).Substratum: bark of Ostrya carpinifolia firewood, lying on ground.Place: Lower Trenta valley, between villages Soa and Trenta, right bank of river Soa, next to the Trenta 2b cottage, East Julian Alps, Posoje, Slovenia. Comments (pertain to pictures in the Flicks album Leucogyrophana mollusca): Few fungi have such a vivid color like Leucogyrophana mollusca. May be Terana coerulea can be compared regarding blue color, or Cortinarius violaceus/hercynicus in its best shape regarding dark violet, or Bisporella citrina. It is small, but it can make a whole few meters long log fascinating vividly yellow. This colors do not fall behind colors of flowering plants. Fungi are very far from being boringly gray-brown creatures. Leucogyrophana mollusca is a corticoid fungus. It grows almost always resupinate. Only sometimes it is effuse-reflexed and forms a kind of small pilei. When it is in its typical form of vividly orange labyrinthine hymenium abundantly surrounded by white mycelia it is easy to recognized. Growing in a few patches, the largest 12 x 3.5 cm; about 1 mm thick, easy to peel off substratum; taste and smell indistinctive, SP yellowish-ocher. Spores smooth. Hypha monomythic, septa with clamps, some also without. Spore dimensions: (5,4) 5,8 - 6,8 (7,3) (3,7) 3,9 - 4,5 (4,9) m; Q = (1,2) 1,4 - 1,6 (1,7); N = 35; Me = 6,3 4,2 m; Qe = 1,5; Olympus CH20, NEA 100x/1.25, magnification 1.000 x, oil (spores); NEA 40x/0.65, magnification 400x (hypha); in water; fresh material.
