Abstract A description is provided for Phaeococcomyces exophialae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Human phaeohyphomycosis (mycoses), subcutaneous phaeohyphomycosis, and corneal ulcers; black yeast cells can be found in host tissues. Rock-inhabiting strains of the fungus also cause destruction of archaeological and museum marble, and colour change in marble. HOSTS: Alnus glutinosa, Homo sapiens. Plant material (e.g., straw). Marble and calcareous rock. GEOGRAPHICAL DISTRIBUTION: AFRICA: Mali. SOUTH AMERICA: Ecuador, Uruguay. EUROPE: Great Britain, Ukraine. TRANSMISSION: In cases of human disease, traumatic inoculation or presumably by air-borne dissemination of conidia.

Abstract A description is provided for Monodictys levis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: A typical soil species also occurring on rocks. With other rock-inhabiting fungi it can deteriorate stone monuments and art objects. HOSTS: Isolated from air, dead wood, herbaceous stems, damp sacking, feathers, plaster, soil (including contaminated soil from spoil heaps), from calcareous rock (marble and limestone), and as a laboratory contaminant. Associated organisms include: Avena sp., Beta vulgaris, Betula sp. (fence post), Cervidae (dung), Eucalyptus tereticornis (leaf), Eucalyptus sp. (seed), Fagus sylvatica (cupule, leaf), Fragaria sp. (root), Humulus lupulus (dry flower), Phaseolus vulgaris, Picea abies, Ricinus communis, Rodentia (dung), Salix sp. and Solanum tuberosum. GEOGRAPHICAL DISTRIBUTION: NORTH AMERICA: Canada (British Columbia). ASIA: India (Kerala), Russia (Russian Far East). AUSTRALASIA: Australia, New Zealand. EUROPE: Belgium, Great Britain, Greece, Russia, Ukraine. TRANSMISSION: By air-borne dissemination of propagules, or through the soil.

AbstractA laboratory experiment was conducted to determine the damage caused by snail grazing to 35 calcicolous lichen species and cyanobacteria from the Baltic island of Oland, Sweden. Individuals of four species of land snails (Balea perversa, Chondrina cliema, Clausilia bidentata and Helicigona lapicida) were allowed to graze on identified lichen species growing on pieces of limestone. Snail grazing on thalli and ascocarps was classified into four categories ranging from no damage to completely eaten. In general, some lichen species were heavily grazed, whereas others were only slightly damaged or not injured. Aspiciha calcarea, Tephromela atra and Verrucaria nigrescens were preferred by all snail species except Chondrina cliema. In general, lichen thalli that were not immersed in the calcareous rock and cyanobacteria were preferred, whereas ascocarps were avoided by one of the snail species (C. clienta). Immersed perithecia with a carbonized outer layer were avoided by all snail species except C. bidentata. Possibilities of chemical and mechanical defence properties in calcicolous lichens are discussed.
