Plants gregarious or cespitose, stipitate with the stems variable 
in length but reaching 1 or 2 cm., irregular, tomentose and at- 
tached by a dense growth of white mycelium which penetrates 
into the substratum binding together the leaves, twigs and leaf- 
mould in which they grow, the stems themselves often clinging 
together in clusters, abruptly expanding above into the cup which 
reaches a diameter of 1 or 2 cm. and about half as deep, exterior 
of the cup and stem white or whitish, the cups pruinose or sub- 
tomentose with poorly developed hair-like structures, hymenium 
bright-orange, color fading in dried specimens ; asci cylindric 
above, tapering below, reaching a length of 300-350^ and 15-17 n 
thick, often becoming strongly spirally twisted at least in dried 
specimens; spores i-seriate, obliquely arranged and often with the 
ends slightly overlapping, ellipsoid, at first smooth and with 
usually two large oil-drops, becoming rough, roughenings taking 
the form of reticulations with the meshes of the reticulations about 
3 ju, in diameter, rarely 5 or 6 fi, ridges extending 1-2 ju, beyond 
the periphery of the spore, entire spore 23-27 X 12-16 m para- 
physes enlarged above, about 6 ^ in diameter, filled with orange 
granules. 
On the ground in coniferous woods.
