This is a cedar-apple rust fungus (кедрово-яблочный гниющий гриб). Just photographed it after rain poured down all night. After the rain, the fungus turns orange and shows its swollen spore-bearing horns. Before the rain, while it grows, it resembles a coronavirus, a ball of reddish-brown cones with spikes (see the photograph in the comments). The botanical name is Gymnosporangium juniperi-virginianae.
