The cap is lemon-yellow, yellow-brown, red-brown to dark brown, fleshy, conical with a sharp umbo, then convex, finally flat and depressed. The cap surface is felty, dry, radially fibrillose then scaly, sometimes with pointy erect scales. The cap margin is inrolled then expanded, thin, with white veil remnants.

The stem is cylindrical, swollen towards its base, hollow even in the youth. It is greenish-yellow below the ring, concolorous to cap above it, whitish at its base like the mycelium. The ring is membranous and thick, ascending, whitish. The stem is dotted with red above the ring, more or less arranged as a (hard to see) network..

The flesh is spongy, not very thick, flesh white to creamy white (lemon yellow close to tubes), with an unchanging colour when in contact with air; its taste is faint, mild; the odour is weak, fruity, pleasant;

The tubes are large, angular (like quadrilaterals), with narrower cells close to the margin, decurrent, not easily removed from cap, rather short (5-10mm), yellow greenish, non turning blue when exposed to air.

The pores are very large (up to 3mm), yellow to olive green (concolorous to tubes), arranged regularly and radially, not changing colour when pressed. The spore print is olive-yellow.

It grows more often in mountainous regions, in small groups on all kinds of substrate: moss, marshlands, grassy areas, on a rather poor and acid soil, exclusively associated to larch.

The fruiting period takes place from June to November.
Dimensions: width of cap approximately 8 cm (between 2 and 18 cm)
  height of stem approximately 6 cm (between 3 and 10 cm)
  thickness of stem (at largest section) approximately 14 mm (between 5 and 25 mm)
  spores : 7-11 x 3-4,5 microns, ellipsoid-spindle-shaped

Distinctive features : cap becoming slightly scaly with age; stem soon getting hollow; membranous ring present on stem; only in association with larch
