Tricholoma moserianum
Tricholoma moserianum is a little-known European mushroom-forming fungus of the agaric genus Tricholoma and family Tricholomataceae. Described as a new species in 1990, it is found in France, where it forms ectomycorrhizal associations with tree in French woodlands. The fungus make a white cap up to 5 cm in diameter with free gills.
Taxonomy
The fungus was formally described in 1989 by the French mycologist Marcel Bon. The type specimen was collected by Bon in a deciduous woodland in France. The specific epithet honours the Austrian mycologist Meinhard Moser.Description
Tricholoma moserianum has a cap that is 3–5 cm in diameter, which is convex and smooth with a predominantly white colouration that sometimes has an ochre centre. The gills are white in colour, immutable, and crowded together. They are not attached to the stipe.The stipe is 5–6 cm tall and 4–7 mm wide, appearing smooth or with occasional scales toward the apex. Like the cap, it is predominantly white with slightly yellowish tones. The spores are broadly elliptical and relatively small for the genus, measuring 4–5 μm by 3–4 μm. The fungus produces white spore prints.
The flesh of the fruit body is white, immutable, and has a greyish appearance in the stipe. It was described as having an earthy odour.
