varying from flattened to, rarely, hemispherical plasmodiocarps, up to ca. 9 x 13 mm and
0.3-0.7(-1) mm high. The surface often with traces of the plasmodial veins, which formed
the fruitbody. The colour in RL varies from light olive-brown to almost chocholate-brown.
Often with a shiny surface.
membranaceous but mostly rather robust, occasionally wrinkled or with thickened,
darker veins. In TL pale olivaceous yellow to olive-brown. On the inner side with
a more or less distinct net-ornamentation of fine lines, meshes 1-3(-9) µm.
of 0.5-1 µm thick, solid threads fixed at the peridium above and at the hypothallus below.
The threads are sparsely branched and run ± parallel. With a finely warted surface.
Olivaceous yellow in TL.
spherical, rarely shortly ellipsoid, same colour as the fruitbody, pale greyish
yellow in TL. Approx. 2/3 to 3/4 of the surface covered with a net-ornamentation, much
like the one of the peridium, formed of ca. 0.5 µm high lists, ca. 8-12 meshes across a
diameter. 6.2-7.0-8.2 µm Ø.
Rotten wood of deciduous trees, among others willow (Salix sp.) and alder (Alnus glutinosa),
Only half a dozen finds in Danmark.
Scattered throughout Europe, Israel, Japan, Australia and western USA.
