Abstract A nationwide survey of New Zealand
sapstain fungi on Pinus radiata was undertaken between 1996 and
1998 with collections of 1958 samples of material from 869 sites in the
North and South Islands. Material was collected from mills, ports,
forest plantations of native, exotic, or P. radiata,
nurseries, farms, and urban areas. Material collected included
branches, twigs, needles or leaves, cones, logs, wood chips, timber,
and veneer. From these collections, 2154 potential sapstain
fungi, representing 14 known species plus a number of unidentified
species, were isolated. The predominant sapstain fungi isolated were Sphaeropsis
sapinea, Ophiostoma ips, O. floccosum, O.
piliferum, Leptographium procerum, and O.
querci. S. sapinea was isolated from all material sampled
including collections from the forest floor (including branches, twigs,
needles, leaves, cones, and logs) as well as from logs and timber. In
contrast Ophiostoma species were mainly found on logs, timber,
and wood chips.
