Powdery Piggybacks

 Powdery Piggybacks found by me in the Forest of Preuilly.

This tiny uncommon mushroom may look small and innocuous but it is much more enigmatic than its simple appearance. Its presence and ability to parasitise and decompose its host, Brittlegill Russula spp mushrooms, is an important indicator of the health of its forest home. 

 

Found on an outing to a woodland at Ferrière les Beaulieu.

The scientific name is Asterophora lycoperdoides and its French name is Astérophore faux-lycoperdon. The miniature mushrooms 'piggyback' in small groups on old Brittlegills, and after starting out powdered white, soon become covered with what looks like cinnamon powder. Hence the English name of Powdery Piggyback mushroom. Unusually for a gilled mushroom, this powder on the top of the cap is made up of asexual spore like reproductive bodies. This is quite unlike 'normal' gilled mushrooms, which produce sexual spores that are dropped from the gills to reproduce.

The species is widespread, and considered to be uncommon, but because of its small size it may be overlooked and under recorded rather than genuinely rare. You are most likely to see it in beech forests, or mixed beech and spruce, in damp places.
