Adreus fascicularis is an arborescent sponge from 10 to 25 cm in height. The branches, usually ramifying in a plan have a diameter from 6 to 8 mm and are tip-tapered. They are smooth, firm to the touch and slightly striated longitudinally. The colour is yellow with the tip of the branches generally brownish. They live attached to rocks, generally on clear horizontal surfaces covered by sand, the base and some branches may be hidden.
Many erected species look similar; its distinctive characteristics are branches with darker and tapering tips.
Adreus fascicularis is found around 20 m deep, in the Atlantic Ocean down to the North of Spain and in the English Channel.
