Quasiconcha reticulata and Its Anamorph from Conifer Roots

Abstract
Q. reticulata is reported from roots of 2 spp. of conifers. Agar cultures from single ascospores produced a dark mycelium bearing chlamydospores. An anamorph similar to the form-genus Chalara developed only on sterile twigs and leaves of Pinus halpensis. Because the fungus was associated with the pine wood nematode [Bursaphelenchus xylophilus] on one occasion it was tested in culture as a food organism for the nematode; it supported growth and reproduction of the nematode at 20 and 24.degree. C.
