“…In the field, it is also associated with other members of the Cistaceae , such as Halimium halimifolium (Comandini & Rinaldi, unpubl.). Besides, according to both our field observations and those of several other authors (Basso 1999, Mua & Casula 2012, Nounsi et al . 2014), this species also grows in association with Quercus in the Mediterranean eco-region.…”

Peering into the Mediterranean black box: Lactifluus rugatus ectomycorrhizas on Cistus

2016

We describe the morpho-anatomical features of the ectomycorrhizas (ECMs) formed by Lactifluus rugatus on Cistus, a genus of about 20 species of woody shrubs typical of the Mediterranean maquis. The description of L. rugatus mycorrhizas on Cistus is the first ECM description of a species belonging to Lactifluus subgen. Pseudogymnocarpi. The ECM identity was verified through molecular tools. Anatomically, the characteristic of L. rugatus mycorrhiza is the presence of abundant, long “bottle-shaped” cystidia on mantle surface. Indeed, the overwhelming majority of milkcap mycorrhizas are acystidiate. This is the third Lactarius/Lactifluus mycorrhiza to have been described associated with Cistus, the others being Lactarius cistophilus and L. tesquorum. The phylogenetic distance between all these taxa is reflected by the diversity of the principal features of their ECMs, which share host-depending ECM features known for Cistus, but are otherwise distinguishable on the host roots. Comparison of Lactifluus rugatus ECM with those formed by L. vellereus and L. piperatus on Fagus reveals elevated intrageneric diversity of mycorrhizal structures. Such a diversity is supported by analysis of ITS sequences of relevant species within European Lactifluus species. Our study extends knowledge of Cistus mycorrhizal biology and confirms the informative value of mycorrhizal structures in understanding phylogenetic relationships in ECM fungi.

“…as mycorrhizal fungus. They were selected at wetlands of the forest and under the trees of the Pinus halepensis [22,31]. Harvested fruiting bodies were immediately stored in wax paper bags and transported to the laboratory [32], aiming the preparation of a fungal inoculum to be used with Pinus halepensis seedlings.…”

This study aims to evaluate the effectiveness of Pinus halepensis inoculated with the ectomycorrhizal fungi spores belonging to Scleroderma in phytoremediation of polymetallic soil. Tailings were collected in the Kettara polymetallic abandoned mine in southern Morocco and diluted with sand in the following proportions, 10%, 25%, 50% and 75%. The pots experiment was conducted for six months under greenhouse conditions. The results show that the studied plant reveals a great tolerance even at high proportion of contaminated soil (75%). The average length and biomass of the aerial and root parts of both inoculated and non-inoculated seedlings decreased with the increase of the proportion of the polluted soil. The inoculated seedlings have shown higher length and biomass than non-inoculated seedlings. The symbiotic association between Pinus halepensis and the fungus Scleroderma could be proposed as an ultimate solution for the phytoremediation of polluted soils.
