In Arctic regions in Ellesmere Land and King Oscar Land, Darbishire[1182] found on bones: Lecanora varia, L. Hageni, Rinodina turfacea and Buellia parasema (disciformis). He could not trace any effect of the lichens on the substratum.
On charcoal—Rinodina exigua, Lecanora umbrina.
On dross or clinkers—Parmelia dubia, Physcia obscura, Ph. ascendens f. tenella, Ph. pulverulenta, Xanthoria parietina, Placodium pyraceum, Pl. citrinum, Rinodina exigua, Lecanora dispersa, L. umbrina, Lecania erysibe.
On glass[1183]—Physcia ascendens f. tenella, Buellia canescens. Richard has recorded the same lichens on the broken glass of walls and in addition: Xanthoria parietina, Lecanora crenulata, L. dispersa, Lecania erysibe, Rinodina exigua, and Buellia canescens.
On earthenware, china, etc.—Physcia ascendens f. tenella, Lecanora umbrina, L. dispersa, Lecania (? Biatorina) cyrtella, Verrucaria papillosa, Bacidia inundata.
On leather—Nearly fifty species or varieties were found by Lesdain on old leather on the dunes. Cladonias, Parmelias and Physcias were well represented with one Evernia and a large series of crustaceous forms. He adds a note that leather is an excellent substratum: lichens covered most of the pieces astray on the dunes. Similar records have been made in Epping Forest by Paulson and Thompson[1184] who found Cladonia fimbriata var. tubaeformis and Lecidea granulosa growing on an old boot. These authors connect the sodden condition of the leather with its attraction for lichens.
On pasteboard—Even on such a transient substance as this Lesdain found a number of forms, most of them, however, but poorly developed: Cladonia furcata (thallus), Parmelia subaurifera (beginning), Xanthoria parietina (beginning), Physcia obscura, Placodium citrinum (thallus), Pl. pyraceum, Lecanora umbrina, Bacidia inundata and Polyblastia Vouauxi var. charticola.
On linoleum—Xanthoria parietina, Physcia ascendens f. tenella, Rinodina exigua, Lecanora umbrina.
On indiarubber—Physcia ascendens f. tenella.
On tarred cloth—Xanthoria parietina, Placodium citrinum, Pl. pyraceum, Rinodina exigua, Lecanora umbrina, Lecania erysibe, Bacidia inundata.
