Memnoniella echinata is a widespread strongly cellulolytic fungus. It has been isolated from cotton, canvas, hardboard and woollen fabrics. Memnoniella echinata is very similar to Stachybotrys but it produces spores in chains. It is common on very wet gypsum board.
Little is known about the medical significance of Memnoniella echinata. However, it produces many of the toxins produced by Stachybotrys chartarum, suggesting that Memnoniella echinata should also be considered potentially dangerous in indoor air.
