The anamorph or asexual reproductive stage. Identified by Neil Mahler. 13 November 2010 Hampshire. Photograph copyright Leif Goodwin
The anamorph, or asexual reproductive stage, forms cushion like growths, which often overlap: surface woolly, whitish, with age becoming yellowish, and then brown and powdery, to about 10 cm across. This is followed by the teleomorph, or sexual reproductive stage which forms resupinate growth and brackets: upper surface velvety, white, underside white, pores angular, 3 to 4 per mm, to about 3 cm wide.
Anamorph: soft, spongey, whitish, with age becoming brown and powdery. Teleomorph: firm, white.
All year but more common in late summer to winter
On dead wood from conifers, favouring stumps, and on the roots of Calluna (heather) on heaths
Chlamydospores brown, basidiospores white
Chlamydospores globose to irregularly ellipsoidal (5-10) x (3.5-7) µm2. Clamp connections seen in the anamorph hyphae. Basidiospores ellipsoidal, smooth (4.5-5.5) x (2-3) µm2
