Mycelophagus castaneae ;* is an imperfectly described form which may belong either to the present group or to the Chytridiales. A serious disease of the chestnut in France is charged to it. Zygomycetes (p. 66) This group of fungi is readily distinguished from the Oomycetes by its isogamous sexual organs, when these are present. In the absence of sexual organs the general type of sporangium is usually sufficient mark of distinction for those who are even but slightly acquainted with the two groups. The mycelium, if young, serves to indicate relationship to the Phycomycetes. Older mycelium is often septate and would lead the unwary into errors of Please note that these images are extracted from scanned page images t
