Slo.: rumeni smetiar - syn.: Bolbitius vitellinus (Pers.: Fr.) Fr., Bolbitius vitellinus var. titubans (Bull.: Fr.) Moser - Habitat: grassland; semiruderal, flat terrain near a village house; calcareous ground, shallow soil layer; nitrogen rich place (my dog's favorite place to pee); open, fairly sunny place; mowed several times per year; exposed to direct rain; average precipitations ~ 3.000 mm/year, average temperature 7 - 9 deg C, elevation 600 m (1.970 feet), alpine phytogeographical region.Substratum: soil.Comments: Bolbitius titubans is generally a common mushroom but apparently not in the Upper Soa River region. The place of this observation is almost in front of my house, where I live. I know this piece of grassland for decades. Yet, I have seen this mushrooms only once - in 2013. There were several dozens of them appearing again and again starting at the beginning of October until the end of November. Pilei are ephemeral and of similar habitus as in genus Coprinus but vividly lemon to yolk yellow, beautiful particularly when they are young. It is impossible to overlook them in low grass. They are viscid and very delicate. Growing solitary and in groups of a few fruit bodies; flesh very brittle; SP brown with reddish tint; smell and taste indistinctive.Spores smooth with thick walls and large germ pore. Dimensions: 12.6 [13.8 ; 14.3] 15.5 x 7.2 [7.9 ; 8.3] 9 microns; Q = 1.6 [1.7 ; 1.8] 1.9; N = 29; C = 95%; Me = 14.1 x 8.1 microns; Qe = 1.7.
