Aspergillales or Blue-green and Brown Fungi.—This group includes perhaps the most widely distributed andfamiliar examples of the fungi. They occur as blue-green orbrown moulds upon almost any organic matter, forming a deli-cate mycelium from which are developed numerous erect the common blue mould, Pcnicillium, these erect hyphae arebroom like (Fig. 142, B) and the spores are formed from thetips of the branches v
