Asconoid type - Ascon type
One of the three basic types of tissue structure (groove system) unique to marine sponges. This is the simplest type, consisting of an erect hollow cluster. It is found in the genus Polytrichum, etc., of the class Calcarea. All sponges show this type in the early stages of development, and then develop into the somewhat more complex Polytrichum type (such as Polytrichum) or the more complex Leucon type.
