Abstract: The anatomy and ontogeny of the rare Cryptomyces maximus have previously been insufficiently known and poorly communicated. It is here described and illustrated in detail based on recently collected material from Norway in different states of development. The parasitism and its role as a pathogen is treated and discussed, as well as its common types of habitat based on our observations in North Norway. Its distribution in Norden is mapped. Finds of this colourful and large ascomycete in this area are curiously few and occasional, and many of those date a century or so back in time. The species also appears to be rare on a global scale. We think the reason for the scattered records both in time and space has been lack of knowledge of its ecology and how it appears in nature.
