Roots of salal (Gaultheria shallon Pursh) collected from forest clearcuts were examined by light and scanning electron microscopy, and the ericoid mycorrhizal fungi were isolated and identified. Heavy colonization of typical ericoid mycorrhizae was present in and restricted to the first of the two layers of root cortical cells. Neither ectomycorrhizae nor arbutoid mycorrhizae were observed. In the field, over 85% of the roots and 90% of the cortical cells within colonized roots were colonized. One hundred and seventy-five of the 278 fungal isolates from salal roots formed ericoid mycorrhizae with salal in the laboratory, and these isolates were grouped into four species based on spore formation and cultural characteristics: Oidiodendron griseum Robak, Acremonium strictwn W. Gams, and two unidentified, nonsporulating fungal species. The association in the laboratory between A. strictum and salal was atypical in that the fungus improved the growth of salal seedlings but was slow to colonize roots and occasionally grew and even sporulated on the shoots. No differences in percent colonization or diversity of ericoid mycorrhizal fungi were found in salal growing on clearcuts from two different forest types.

Ericoid Mycorrhizal Fungi

Using restriction fragment length polymorphism (RFLP) patterns from two ribosomal internal transcribed spacers (ITS) and DNA sequences from ITS2, we characterized ericoid mycorrhizal fungal isolates from culture collections.With a synoptic key to RFLP patterns, we divided 34 mycorrhizal or root-associated isolates into 16 groups. RFLP patterns were identical when fungal specific primers were used to amplify DNA from pure fungal cultures and in vitro mycorrhizae. Sequence analysis clustered 23 of 24 mycorrhizal isolates into two larger groups: the Oidiodendron group and the Hymenoscyphus group. The Oidiodendron group included genetically uniform, conidiating fungi. The Hymenoscyphus group encompassed more diversity and included other discomycetes (Leotiales) as well as sterile, unidentifiable mycorrhizal isolates from four RFLP groups. Results from our field site on Vancouver Island, British Columbia, Canada, suggest that several ericoid mycorrhizal fungi can coexist in a single root of Gaultheria shallon Pursh and that our molecular data base is not yet complete. From sixty 3-mm root sections, we cultured four genetically different fungi that formed mycorrhizae in resynthesis experiments and sequence analysis showed that one of these differed from all previously known ericoid mycorrhizal fungi.

In Vitro Inoculation

Inoculation of microshoots of Pieris floribunda (Pursh ex Sims) Benth. and Hook. (mountain andromeda) with isolates of Hymenoscyphus ericae (Read) Korf and Kernan ericoid mycorrhizal fungi stimulated growth during 1 month in vitro. However, no benefits were apparent after 3 months in a greenhouse. Acclimatization of plantlets of P. floribunda to greenhouse conditions following in vitro inoculation improved survival (42% vs. 16% for controls). The protocol reported herein is similar to procedures utilized currently for micropropagation of various ericaceous species and has potential to improve plantlet survival during acclimatization.
