Description: Amerospores represents a morphological category of spores that are produced by many unrelated fungi. Instead amerospores are identified by increasing magnification to detect subtle characteristics. When no characteristics are present that allow identification of any spore, we list it as “other dark” or “other colorless”. These terms make clear the fact that we have not identified these spores and, importantly, separates these into a small group of spores, enabling better interpretation of the data when comparisons are made between locations. Generally, very few spores fall into the “other” or unidentified category.
