Observation 217892: Lycoperdon lividum Pers.

Code: Bot_915/2015_DSC9064
Habitat: dry pasture occasionally still grazed by sheep, moderately inclined terrain, south east aspect; calcareous, colluvial, skeletal ground; open, warm, sunny place; exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 610 m (2.000 feet), alpine phytogeographical region.

Substratum: sandy soil.

Place: Lower Trenta valley, right bank of river Soča, between villages Soča and Trenta, Na melu place near cottage Trenta 2b, East Julian Alps, Posočje, Slovenia EC.

Comments: Growing in a group of three sporocarps; their dimensions (diameter/height in mm) 22/18, 20/17 and 15/13; SP and mature, cottony-powdery gleba umbra brown, aoc735.

Features of the collection such as (small) dimensions of sporocarps, color of gleba and SP, spores with very short apiculus, no apiculus fragments present, abundant capillitium, with fragile, very sparsely branched, thick walled hypha without septa, as well as habitat and substratum argue for its belonging to Lycoperdon lividum. Subgleba was whitish when sporocarp was freshly cut and light brown later when dry without membranous separation from gleba. However, there was not much of it. Literature states that it can occupy up to 1/5 (Ref.:5) (up to 1/3 in Ref.: 3) of fruitbody volume, which was not the case with this collection.
