Russulaceae
notes Slo.: osmojena golobica - syn.: Agaricus adustus Pers., Omphalia adusta (Pers.) Gray, Russula eccentrica Peck, Russula subusta Burl, Russula nigricans Fr. - Habitat: mixed Fagus sylvatica forest with scattered Picea abies, a closest large Picea abies at about 5 m distance, a small one about 3 m; moderately inclined mountain slope, SE aspect; dry place; calcareous, colluvial, skeletal ground with scattered rocks; in shade; partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 560 m (1.840 feet), alpine phytogeographical region. - Substratum: soil, humus, rotten fallen leaves. - Comments (pertain to Flickr album Russula adusta): This Holarctic species known from almost all European countries is a member of charred russulas (subgenus Compactae). Similar species include Russula albonigra, Russula nigricans. Russula anthracina and R. densifolia. All of them are medium sized or large but often hidden under fallen leaves or other ground debris. They are not colorful. When young they are muddy whitish or grayish but they soon become dark muddy brown, dark gray of black. They all bruise to black or dark gray. A dry Russula adusta looks like a put out site of fire (see Fig. 14.) When old and covered by all kind of ground debris and usually growing in deep shade they are not at all attractive. It is not always easy to determine them to species level particularly if they are old. - Charred russulas have generally white spore print. Only two of them have beige spore print – Russula adusta and Russula anthracina (Ref. 2). The spores of both species are very similar and hence not a useful trait to distinguish them. The reason that we decided for the former was the smell, which was strong, musty, unpleasant (some say on old wine barrels). During drying a small piece of the specimen its unpleasant smell was noticeable in the whole room. - Russula adusta forms mycorrhiza mainly with conifers. However, in montane regions it can be found also in beech forests with scattered Picea abies or Pine species (Ref.:3). It grows only - xceptionally in pure broadleaved forests. - Three (quite old) pilei found; pilei diameter 7-9 cm, taste of flesh mild, mushroomy, on earth; taste of gills distinctive on some kind of chemistry; smell strong, unpleasant, musty, on dirt socks; during drying of a specimen awful; SP pale beige, oac7; pilei cuticle peeling modest; bruising black but not rapidly; when dry completely black apart of dark gray gills. - Spores with low incomplete mesh and some warts. Dimensions: (7,2) 8 - 9,1 (9,3) × (6,4) 6,7 - 7,8 µm; Q = (1,1) 1,14 - 1,28 (1,3); N = 32; Me = 8,6 × 7,1 µm; Qe = 1,2.
