What do Basidiomycetes mean in our indoor air samples?
Out of our twelve samples, two samples show not a single spore of mold and two others show only a Basidiospore count of 133 (4 spores in each sample of 30 liters). In the most recent tests that we had done the outdoor Basidiospore count was 3110. Two of our samples had Basidiospore counts of 1,470. Does your point about different species apply to Basidiospores as well? In other words, does a high level of Basidiospores in the wall indicate a problem even when the number is significantly lower than the outdoors? It seems that the outdoor counts of basidiospores were quite high on the days in question and we wondered whether the high indoor counts were really due to outdoor air or just appeared unproblematic because the outdoor sample was so concentrated on the date in question. Basidiomycetes are common in outdoor air, and represent a very large group of spore genera/species. Certain basidiomycetes are very often present in our samples in the Northeast U.S. such as two of our good-looki
