Ciri dan struktur
The species is characterised by a grey-white hypothallus or very thin thallus covered by groups of white, farinose to granular soredia or by being completely sorediate. Ascomata and pycnidia are unknown. Atranorin is the only secondary metabolite. The species occurs in old-growth forests on bark of broad-leaved trees with high bark pH (> 5). The thallus consists of a hypothallus (i.e. without photobiont cells) or, in some parts, a lichenised and thinly episubstratal thallus (up to 100 μm high), which is smooth or partially areolate, pustulate or granular, grey-white to grey, sorediate. A prothallus is absent or very thin and white. Soredia are not produced in clearly delimited soralia, but dispersed in groups or forming a more or less continuous layer, white or, when fresh, yellowish-white, farinose to granular, simple, (25–)35–65 μm in diam., or in consoredia up to 125 μm in diam. Soredia are enclosed by a colourless, more or less compact “wall” without projecting hyphae. The photobiont is trebouxioid, and 5–16 μm in diameter. Ascomata and pycnidia are unknown.
Habitat dan peran ekologis
The new species is reported from the Czech Republic, Poland, Russia (European part of the Caucasus) and Ukraine. It has already been published under a provisional name, Bacidia albogranulosa ined. from the Czech Republic (Vondrák et al. 2016) and the Ukrainian Carpathians (Malíček et al. 2018, Vondrák et al. 2018). Bacidia albogranulosa grows abundantly in old-growth floodplain and scree forests in the Czech Republic and old-growth ash or hornbeam dominated broad-leaved forests in Poland. It rarely occurs in old-growth beech (Ukraine) and mixed forests (Russia). It has usually been found on a dry and coarse bark of broad-leaved trees with a relatively high bark pH (approximately > 5). The most frequent phorophytes are Acer campestre (n=5), A. platanoides (11) and Fagus orientalis / sylvatica (4; overmature or dying trees due to a fungal infection). A few specimens were recorded also on Fraxinus angustifolia (2), F. excelsior (2), Carpinus orientalis (1), Euonymus europaeus (1) and Quercus sp. (2). The species prefers rather shaded trunks and places not directly exposed to rain, similar to many Lepraria species (Saag et al. 2009). Alyxoria varia (Pers.) Ertz & Tehler, Bacidia rubella and the non-lichenised fungus Dendrothele acerina (Pers.) P.A.
