Hypomyces Tul.; anamorph Cladobotryum Nees
Hypomyces species, especially H. rosellus (Alb. & Schw.) Tul. (anamorph Cladobotryum dendroides (Bull.) W. Gams & Hoozemans) cause the economically significant cobweb disease of cultivated mushrooms, attacking Pleurotus as well as Agaricus culture (van de Geijn, 1982; Gray & Morgan-Jones, 1981). A useful review of the older literature is given by Arnold (1976), and modern taxonomic treatments are given by Gams & Hoozemans (1970) and de Hoog (1978).
