General Description:

Characteristics in brief (based on data by Høiland 1990, Ludwig 2001): Fruitbodies small, pileus up to 25 mm, bright coloured, orange red-brown, with almost smooth surface, at most finely fibrillose-scaly, taste bitter- ish, spores ovoid-ellipsoid to amygdaliform, (6–)6.5–7.5(–8.5) × (3.5–)4.0–4.8(–5.5) μ m, verrucose. Growing on sandy or peaty soil and on burnt places in conif- erous forests, heathlands and mires, very rare.

Description: I have not seen fresh fruitbodies in the field. For recent descriptions see Høiland (1990: 275), Ludwig (2001: 162).

Fructification: May–November (Høiland 1990, Ludwig 2001).

Ecology: The following substrates and habitats are given in reliable literature (Høiland 1990, Ludwig 2001): sandy or peaty soil and burnt places in coniferous forests, heathlands and mires.

Distribution: The presence of Gymnopilus odini in the Czech Republic is neither reported in reliable literature nor documented by herbarium specimens. I suppose that the species grows here but its occurrence has not been proved to date. The species is known from many European countries but seems to be very rare elsewhere.

D i s c u s s i o n : See discussion on Gymnopilus decipiens.

Slightly aberrant finds from Sphagnum stands were published by Bon et Roux (2002: pl. 8-B, p. 45) and Cetto (1970–1993: no. 2670). Moser et al. (2001) described a related species, Gymnopilus turficola M.M. Moser et H. Ladurner, growing in palsa mires on peat in subarctic areas in Norway and Finland. Its distinguishing characters are the olive-brown pileus (the only European species having greenish colours), bluish to yellow-green lamellae when young, dextrinoid spores, presence of pleurocystidia, strong odour of iodoform and habitat on peat in subarctic to arctic regions.
