When: 2008-09-01

Collection location: Akademgorodok, Novosibirsk, Russia [Click for map]

Who: Tatiana Bulyonkova (ressaure)

No specimen available

A relatively rare Tricholoma in our pine forest, often fruiting buried deep under pine needles and partially in sandy soil. It may be more common in less disturbed habitats to the South of here, but here it is almost always found solitary, and fruitbodies are of very modest size.

Absolutely right,

I noticed how similar these are to the mushrooms you posted. They grew in what’s called ленточный бор here, tape pine forest, a type of naturally occuring Pinus sylvestris forests common in Western Siberian plains. These are long and relatively narrow stretches of pine forest on ancient sand dunes left by giant muddy currents from melting glaciers at the end of the last Ice Age. The soil there is very sandy – actually, it’s almost pure sand under a thin layer of litter.

And right, parts of the forest where it grows are also where local species of Hydnellum and Sarcodon grow.

If you look at a satellite map of Novosibirsk, you’ll see those dark green stretches along river Ob and in parallel stripes going north-east.

A cute one

The fruiting habits are the same here in Scandinavia, they are easiest to find in older pine forests on sandy soil, but not too mossy, and they are usually just one or two at the same spot. It prefers burnt forests like many other species of Tricholoma, and as Sarcodon and Hydnellum. I was thinking about the host, is Pinus sylvestris the common pine species in your area?
