is '' Coras medicinalis'' (so named because its web was used in medicine).
These spiders are frequently found at or near ground level, or in cellars of houses, where they construct small and rather messy sheet webs on the ground and attached to nearby more elevated things. These webs are small in area and are connected to tubular retreats with simple signal or catching threads radiating from entrance.
