Lying below the mushroom shaped gland is conglobate gland of uncertain function. The mushroom gland of male cockroach possesses long,blind tubules at its periphery called uricose glands or utriculi majoris.These tubules store uric acid and discharge it over spermatophore during copulation.When the spermatophores come to the environment,the waste materials are cast off.Thus,they act as"storage excretory organs" between matings and as actively excretory organ during … etc. segments) and phallic gland.
