location
Lower Trenta valley, between villages Soča and Trenta, Na melu place, near Trenta 2b cottage; East Julian Alps (Posočje, Slovenia)notes Slo.: oskorjena smrkljevka - syn.: Mucilago spongiosa (Leyss.) Morgan, Spumaria alba (Bull.) Dc. - Habitat: Former pasture; under Tilia platyphyllos canopy; slightly inclined mountain slope, southeast aspect; shallow soil layer, calcareous, colluvial, skeletal ground; partly protected from direct rain by tree canopy; average precipitation ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 600 m (2.000 feet), alpine phytogeographical region. - Substratum: fallen off leaves and small dead branches of Tilia platyphyllos. - Comment: Mucilago crustacea is a cosmopolitan species (north hemisphere only) not rare in calcareous regions (Ref.: 4). It is easy to be recognize by its characteristic habitus. Aethalia are composed of clumps or networks of very irregular tubes. As a whole they look whitish. The species can be eventually confused by some unusually looking species from genus Fuligo. But under the microscope they can be unmistakably separated. The cortex of Fuligo species is composed of +/- rounded calcareous grains, while the cortex of Mucilago crustacea is composed of calcareous (lime) crystals, which are easy to be seen under the microscope. The find was solitary. - Three varieties of this species have been described in literature (Ref.: 1) - Mucilago crustacea var. crustacea, Mucilago crustacea var. solida and Mucilago crustacea var. dictyospora. The last one has reticulated not warty/spiny spores and Mucilago solida has significantly smaller spores than this observation and partly much broader capillitium threads (Ref.: 1). This pictures therefore show var. crustacea. - Spores densely warty, globose to sub-globose. Dimensions (without warts/spines): (13,9) 14 - 15,8 (15,9) × (12,4) 12,8 - 14,2 (14,3) µm; Q = 1 - 1,1 (1,2); N = 12; Me = 14,8 × 13,6 µm; Qe = 1,1.
