Remarks (public): The existing material is very scanty and does not allow a full examination and e.g. the formation of the conidia is still not fully known. It seems clear that the spores produce sprout-cells in a yeast-like manner, which makes the species different from all other corticioid fungi. The sprouting is certainly not comparable or analogous to the spore repetition found in many corticioid species and many groups of Heterobasidiomycetes.

Description:Christiansenia mycophaga (M.P. Christ.) Boid. - Bull. Soc. Linn. Lyon 39: 136, 1970; Ceratobasidium mycophagum M.P. Christ., Dansk Bot. Arkiv 19:45, 1959.
Fruitbody very small and thin, forming rounded patches, 1 cm or less in diameter, light salmon-coloured and with a minutely floccose margin.
Hyphal system monomitic, all hyphae with clamps, thinwalled, 1.5-2 µm in diameter.
Basidia of variable length, 20-40 x 5-7 p m, normally with 4 sterigmata.
Spores subglobose, hyaline, thinwalled with oildrops in the protoplasm, 6.5-8 x 4.5-6 µm, germinating with globose yeastlike sprout-cells, 1.5-2 µm in diameter.
Conidiophores hyphal with widened fusoid cells. Conidia 5-7 x 2-3 µm, born from clamps or from projections arising from the clamps.
Habitat and distribution. Only known from the type, which was found parasitic on Leucogyrophana mollis in Denmark.
