Memnoniella echinata is an indoor mould very similar to Stachybotrys chartarum. The only obvious difference between the two moulds is that Memnoniella echinata produces spores in chains while Stachybotrys chartarum produces its spores in a mass. Memnoniella echinata was previously named Stachybotrys echinata.

Memnoniella echinata has a world-wide distribution and is mainly isolated from soil. Similar to Stachybotrys, it is isolated from cellulose containing materials such as paper, wallpaper, textiles and dead plant material. Sometimes both Memnoniella echinata and Stachybotrys chartarum occur on the same water damaged building material.

Memnoniella echinata produces toxic metabolites similar to those of Stachybotrys chartarum.
