摘要: AbstractConsecutive underwater observations carried out in shallow waters of Pontetto (Ligurian Sea) from June to the end November 2013 revealed presence purple areas on white surface asconoid calcareous sponge Clathina coriacea. Histological and ultrastructural investigations performed showed occurrence a network hyphae an indeterminate fungus permeating tissues presumably responsible for unusual colour sponge. The hyphae, varying size morphology according their location body, are visible outermost and, after crossing mesohyl, penetrate inwards into choanodermal layer, being mainly located along apical border choanocytes. undamaged flagella microvillar fringes, which organelles characterising choanocyte cells, is consistent with normal functionality tissues, notwithstanding funga...
