Some kind of mushroom...

Myconids
15 mm scale

Myconids are a peaceful, telepathic race of mushroom creatures who live in the D&D world's "Underdark" caverns.  These Khurasan figures could be peaceful Myconids wishing to be left in peace by more aggressive species... or menacing and harmful Cursed Myconids defending themselves with bursts of necrotic spores.

I can never look now at the Milky Way without wondering from which of those banked clouds of stars the emissaries are coming. If you will pardon so commonplace a simile, we have set off the fire-alarm and have nothing to do but to wait. 

I do not think we will have to wait for long.

- Arthur C. Clarke "The Sentinel", 1951

A Fenris Games resin model.  It makes an impressive 15mm piece, or a merely disturbing 28mm one ;)

Addendum: a better idea of the scale here...
