“…The dominance of taxa belonging to the genus Piloderma in this study, is consistent with the ecological importance of this genus in many boreal forest ecosystems (Erland & Taylor, 1999). Piloderma fallax , a species commonly identified in other studies (often referred to as P. croceum ), was restricted to the organic and eluvial horizons.…”

Summary• Studies of ectomycorrhizal fungal communities in forest soils are usually restricted to the uppermost organic horizons. Boreal forest podzols are highly stratified and little is known about the vertical distribution of ectomycorrhizal communities in the underlying mineral horizons.• Ectomycorrhizal root tips were sampled from seven horizons in three continuous columns of a 52-cm deep podzol profile. Root tips were sorted into morphological groups and the colonising fungi identified by sequencing of the rDNA ITS region. The vertical distribution of mycorrhizal taxa was examined.• A relationship between ectomycorrhizal species composition and soil horizon was found. Tomentellopsis submollis , three Piloderma species and Dermocybe spp. were found predominantly in the upper horizons while Suillus luteus , Lactarius utilis and three undescribed Piloderma species were associated with the mineral horizons.• Two thirds of the root tips were found in the mineral soil and half of the taxa were restricted to the mineral horizons. The results highlight the need to include the mineral soil in order to gain a more accurate representation of the ectomycorrhizal community.

“…Awareness of this limitation has increased in recent times in particular because DNA fingerprinting methods (White et al ., 1990; Gardes & Bruns, 1993, 1996; Gardes et al ., 1991) have revealed the importance of groups of fungi which have been hitherto overlooked because they produce inconspicuous hypogeous or resupinate fruit bodies. These can occupy a large proportion of the ECM root population in boreo‐temerate forests (Baar et al ., 1999; Erland & Taylor, 1999; Kõljalg et al ., 2000; Dahlberg, 2001). Amongst the basidiomycetes, members of the genera Tomentella (Kõljalg, 1996), Tomentellopsis (Thelephoraceae) (Kõljalg et al ., 2000) and Tylospora (Corticiaceae) (Taylor et al ., 2000) are prominent.…”

SummaryProgress towards understanding the extent to which mycorrhizal fungi are involved in the mobilization of nitrogen (N) and phosphorus (P) from natural substrates is reviewed here. While mycorrhiza research has emphasized the role of the symbiosis in facilitation of capture of these nutrients in ionic form, attention has shifted since the mid-1980s to analysing the mycorrhizal fungal abilities to release N and P from the detrital materials of microbial faunal and plant origins, which are the primary sources of these elements in terrestrial ecosystems. Ericoid, and some ectomycorrhizal fungi have the potential to be directly involved in attack both on structural polymers, which may render nutrients inaccessible, and in mobilization of N and P from the organic polymers in which they are sequestered. The advantages to the plant of achieving intervention in the microbial mobilization-immobilization cycles are stressed. While the new approaches may initially lack the precision achieved in studies of readily characterized ionic forms of N and P, they do provide insights of greater ecological relevance. The results support the hypothesis that selection has favoured ericoid and ectomycorrhizal systems with well developed saprotrophic capabilities in those ecosystems characterized by retention of N and P as organic complexes in the soil. The need for further investigation of the abilities of arbuscular mycorrhizal fungi to intervene in nutrient mobilization processes is stressed.

“…Recent below-ground fungal community studies of ectomycorrhizal fungi (Gardes & Bruns 1996, Erland & Taylor 1999 have shown that in a variety of forest types the most important mycorrhizal fungi belong to corticioid and tomentelloid species with resupinate fruit bodies. Accordingly it is logical to assume that the resupinate fruit body type represents an advanced way to produce basidiospores.…”

Taxonomy and phylogeny of Hydnellum gracilipes (P. Karst.) P. Karst. (Thelephorales, Hymenomycetes) was revised. The species is characterized by soft and resupinate sporocarps, and the morphology supports a close relationship with tomentelloid fungi. The phylogenetic interpretation of the sequence data from the 5' end of nuclear large subunit (nucLSU) rDNA showed, however, that the closest relatives of H. gracilipes are found in the genus Hydnellum P. Karst. The evolution of the resupinate fruitbody is outlined. The ecology of the species is discussed and it is proposed that H. gracilipes is a mycorrhizal fungus. Six new localities are listed.
