This is the third in a series of publications of monographic studies of Hypomyces (Fries) L.-R. Tulasne (1860) (Hymenoascomycetes, Hypocreales). In earlier papers we described the species that occur on discomycetes (Rogerson and Samuels, 1985) and on boletes (Rogerson and Samuels, 1989).
Species of Hypomyces can be divided along the lines of their substrata, with the vast majority found on boletes, agarics, or polypores and with little overlapping among the broad substratum groups. More species of Hypomyces occur on members of the Aphyllophorales than on any other host group. Nineteen species, five of them new species, are recognized as occurring on polypores and other members of the Aphyllophorales; 10 names are placed in synonymy. In contrast to most agaricicolous (Rogerson, 1950; Helfer, 1991) and boleticolous (Rogerson and Samuels, 1989; Helfer, 1991) species of Hypomyces, those occuring on polyporaceous fungi, for the most part, are not host specific (see also Helfer 1991). Some appear to be restricted to members of the Polyporaceae (sensu latiore), a few others appear to be host specific, e.g., Hypomyces albidus on Stereum sanguinolentum, H. polyporinus on Trametes virsicolor. Others occur on a wide range of genera and species of diverse families in the Aphyllophorales, particularly in the Stereaceae; some also occur rarely on members of the Agaricales, jelly fungi, and on ascomycetes. A few are sometimes found on nonfungous substrata such as bark and wood (e.g., H. rosellus, H. tegillum). In general, proven anamorphs of Hypomyces species are found on a wider diversity of hosts than their teleomorphs.
