Moser, Lyophyllum cinerascens (Buill.) GillerClustered Domecap, Fried Chicken Mushroom, DE: Brauner Buschelrasling, Frostrasling, SimmerlingSlo.: rjavi zajekDat.: Sept. 17. 2014Lat.: 46.35994 Long.: 13.70335Code: Bot_838/2014_DSC4296 Habitat: mixed wood, Fagus sylvatica and Picea abies dominant trees; modestly steep, SE oriented mountain slope; shallow, skeletal soil layer, overgrown calcareous sand, stone and rocks; relatively dry and warm place; in shade; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 585 m (1.920 feet), alpine phytogeographical region.Substratum: forest soil, under Fagus sylvatica. Place: Lower Trenta valley, right bank of river Soa, between villages Soa and Trenta, next to the trail from Trenta 2b cottage to Trenta 2a, 25 m north of Trenta 2a, East Julian Alps, Posoje, Slovenia EC.Comments: Lyophyllum decastes is actually an aggregate of quite differently looking mushrooms. Many species names have been used in this group. Authors still have different approach to them. I follow Krieglsteiner's view (Ref.2) (without my own arguments, but because it is the simplest for me), who considers Lyophyllum decastes, Lyophyllum fumosum, Lyophyllum loricatum, Lyophyllum aggregatum, Lyophyllum conglobatum and Lyophyllum cinerascens a single very variable species. Again and again fruit bodies are found with all possible intermediate properties forming an apparent continuum among these species. Growing in groups of several fruit bodies on two places some 100 m apart (see also observation Bot_838/2014_DSC4273 in the same day); pileus diameter up to 5.2 cm, viscid with young fruit bodies; cuticle thick, rubbery, peels easily; stipe up to 4 cm tall and 1.5 cm in diameter; hollow with older fruit bodies; sporocarps markedly fleshy and firm; taste mild, mushroomy, after some time slightly bitter; smell indistinctive, almost none.Herbarium: Mycotheca and lichen herbarium (LJU-Li) of Slovenian Forestry Institute, Vena pot 2, Ljubljana, Index Herbariorum LJFFile names: from Lyophyllum-decastes_raw_10.xxx to Lyophyllum-decastes_raw_15.xxx.Ref.:(1) G.J.
