BOOTH, T. 1983. Lignicolous marine fungi from Slo Paulo, Brazil. Can. J. Bot. 61: 488-506.Lignicolous substrates, i.e., wood and leaves, were collected from 10 Slo Paulo State locations and 2 Pernambuco State sites. These were subsequently surveyed and incubated and (or) washed, macerated, and plated on culture media. Six types of wood and mangrove leaves were placed in exposed and buried digestors, recovered, surveyed, incubated, and resurveyed for marine fungi. Of a total of 69 isolated taxa, 32 species, including 24 ascomycetes, seven fungi imperfecti, and one basidiomycete, are discussed. , and ecological considerations are presented for each species. A possible Scolecobasidium-Septoria-Mycosphaerella anamorphic-teleomorphic association is suggested. BOOTH, T. 1983. Lignicolous marine fungi from S5o Paulo, Brazil. Can. J.
