An increase in a form of arbuscular mycorrhizal (AM) fungi, termed fine endophyte or fine root endophyte (Glomus tenue (Greenall) I.R. Hall), is often observed under extreme environmental conditions. We investigated the influence of host plant species, waterlogging and landscape zone (soil type) on colonisation by fine root endophyte. Colonisation by AM(More)
Fine endophytes (FE),Glomus tenue, are traditionally considered to be arbuscular mycorrhizal fungi (AMF) with distinctive microscopic morphology when stained. FE have fine hyphae (c. 1.5 lm diameter) which branch intra-cellularly in a distinctive fan-like pattern (Gianinazzi-Pearson et al., 1981; Abbott, 1982). The hyphae contain small swellings along their(More)
The structures of arbuscular mycorrhizal (AM) fungi (hyphae, arbuscules, vesicles, spores) are used to make inferences about fungal activity based on stored samples, yet the impact of storage method has not been quantified, despite known effects of temperature and host condition on AM fungal colonisation. We measured how four storage treatments (cool or(More)
Fine root endophytes (FRE) are arbuscule-forming fungi presently considered as a single species—Glomus tenue in the Glomeromycota (Glomeromycotina)—but probably belong within the Mucoromycotina. Thus, FRE are the only known arbuscule-forming fungi not within the arbuscular mycorrhizal fungi (AMF; Glomeromycotina) as currently understood. Phylogenetic(More)
