This genus of fungi is known as Ulocladium and can commonly be found in the damp/wet areas of your home. Ulocladium has been known to cause hay fever, plant disease, and other serious infections within those who may be immuno-suppressed. This strain of mold is often found growing along with stachybotrys, a strain of mold that is also likely to cause serious health problems.
If you suspect that this mold may be in your home, contact your local inspector as soon you can. Especially if your home has had extensive water damage in the past.
