“…interaction restricted to few taxa of plants and fungi (Straker 1996), ERM symbiosis is now recognized to encompass a diverse assemblage of symbiotic fungi that features culturable ascomycetes in the Helotiales and Onygenales, but also unculturable basidiomycetes in the Sebacinales . Fungal symbionts in the Helotiales are mostly grouped in the "R. ericae aggregate", a large clade first identified by Vrålstad et al (2002) also including sequences of ECM fungi and root endophytes from other host plants.…”

Living organisms establish complex networks of mutualistic and antagonistic interactions in nature, which impact strongly on their own survival and on the stability of the whole population. Fungi, in particular, can shape natural as well as manmanaged ecosystems due to their ubiquitous occurrence and the range of interactions they establish with plants, animals and other microbes. This review describes some examples of mutualistic and antagonistic fungal interactions that are of particular interest for their ecological role, or because they can be exploited by man to improve plant health and/or productivity in sustainable agriculture and forestry.

“…Ericoid mycorrhizas are important to the health, survival and competitiveness of plants in the Ericaceae (found predominantly in the Northern Hemisphere) and the Epacridaceae (found predominantly in Australia) of the Ericales (Straker, 1996). Analysis of 28S ribosomal DNA (rRNA) (Cullings, 1996) suggested that the Ericales probably evolved in Gondwana in the Mesozoic period and spread to Asia, Europe and the New World (Specht, 1977).…”

This study investigated the relationships between ericoid mycorrhizal endophytes of the Ericaceae (Northern Hemisphere) and the Epacridaceae (Australia). Over 200 fungi were isolated from the roots of two species of Epacridaceae from Victoria, Australia. The isolates were divided into 12 groups by morphology on quarterstrength potato dextrose agar. All were slow-growing and most were dematiaceous, but groups varied from white through pink to dark olive. The ITS1-5.8S-ITS2 ribosomal DNA was amplified and sequenced from eight isolates, forming typical ericoid mycorrhizal morphology in Epacris impressa and one nonmycorrhizal isolate. Sequences were compared, by using similarities and maximum-parsimony analysis, with those of Hymenoscyphus ericae (Leotiales) and Oidiodendron species (Hyphomycetes), the most common endophytes of the Ericaceae. Maximum-parsimony analysis produced four clusters : (1) all Oidiodendron species (at least 90% similarity) ; (2) all five Victorian dark grey-olive isolates (at least 96% similarity) ; (3) one Victorian isolate and Cistella grevillei (88% similarity) ; (4) two light-coloured Victorian isolates and H. ericae (81% similarity). This suggests that these isolates from the Epacridaceae do not belong to the same species as those forming ericoid mycorrhiza in the Ericaceae.

“…The distribution of H. ericae is probably global, being found wherever the Ericaceae or Epacridaceae (Ericales) occur (Egger and Sigler 1993, Hambleton and Currah 1997, Chambers et al 1999, Straker 1996. The species has also been implicated in the formation of mycorrhizas in Pinaceae (Vralstad and Schumacher 1998) or mycorrhiza-like structures in liverworts (Chambers et al 1999) in habitats where these species occur concurrently with ericaceous shrubs.…”

“…Although many of the ericaceous plant hosts have a circumboreal distribution, there are only a few localized reports concerning the identity of their mycorrhiza-forming fungi. H. ericae has been reported with Ericaceae and Epacridaceae worldwide (Egger and Sigler 1993, Straker 1996, Hambleton and Currah 1997, Chambers et al 1999 whereas Oidiodendron maius has been reported primarily from western Canada, Britain, and Italy (Hambleton 1998, Stoyke and Currah 1991, Douglas etal.1989, Perottoetal. 1994, 1996.…”

Scytalidium vaccinii was isolated from roots of Vaccinium vitis-idaea and Oidiodendron maius was isolated from roots of Vaccinium vitis-idaea, V. myrtillus, and Empetrum nigrum, all of which were collected on a fjell at Kevo Subarctic Research Station in northern Finland. Both fungal species are mycobionts in ericoid mycorrhizas. These reports extend the kno\ n ran ge of the common endomycorrhi zal fungi and indicate that these taxa have a circumboreal distribution with ericaceous plants.
