halophilous grassland is dominated by Asteriscus maritimus and Daucus carota subsp.
This new species occupies exclusively open habitats of calcicolous
rosemary scrub on rosemary (Rosmarinus officionalis).
viridissima, Lecania erysibe, Phaeophyscia chloantha, Physcia undulata, Punctelia constantimontium, Punctelia subpraesignis Pyxine berteroana and Teloschistes chrysophthalmus, whereas in mortars in Spain there are crustose, calcicolous
species and only three foliose ones (Arino et al., op.
It differs in that its substrate is more treacherous (usually floating), the groundwater is not under pressure, no marl is present in the sediment profiles, and extremely calcicolous
species such as Parnassia glauca and Selaginella are absent.
Most taiga forests grow on acidic rocks, and so calcicolous
plants are almost absent or are highly localized.
mosses of the family Amblystegiaceae, including Calliergon stramineum, Colliergon trifarium, Campylium polygamum, Drepanocladus aduncus and Scorpidium scorpioides, dominated the fens.
In the Loire valley, Humulus lupulus and Evonymus europaeus reach large sizes in Querco-Ulmetum, whereas all the calcicolous
species cited above are rare or absent.
Finally, cluster D incorporated nine samples with low levels of clustering consistent with a grouping of calcicolous
beech forests (samples 8, 9, 13, 16, 17 and 18) and subalpine calcareous grasslands (samples 10, 11 and 12).
A taxonomic study of the calcicolous
endolithic species of the genus Verrucaria (Ascomycotina, Verrucariales) with the lid-like and radiately opening involucrellum.
