Description:

Pholiota squarrosa (Vahl) P. Kumm., syn.: Agaricus squarrosus Bull., Dryophila muelleri (Fr.) Khner & Romagn., Hypodendrum floccosum (Schaeff.) Overh., Lepiota squarrosa (Vahl) Gray, Pholiota muelleri (Fr.) P. Karst., Stropharia squarrosa (Vahl) Morgan.Family: StrophariaceaeEN: Shaggy Scalycap, DE: Sparriger SchpplingSlo.: hrapavi luskinarDat.: Oct. 10. 2020Lat.: 46.41492 Long.: 13.75772Code: Bot_1338/2020_DSC05579Habitat: old, unmaintained, Picea abies mountain forest; moderately incline mountain slope, southeast aspect; calcareous ground; protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 2-4 deg C, elevation 1.625 m (5.300 feet), alpine phytogeographical region.Substratum: roots and base of an old, alive Picea abies tree.Place: Trenta valley, south slopes of Mt. Prisojnik, near Kranjska planina, East Julian Alps, Posoje, Slovenia EC. Comments: A nice group of still young pilei of this interesting species was growing under an old large mountain Picea abies. This is unusual since this species more frequently grows on broadleaved trees. The grown up pilei become much larger than those shown on these pictures. Pholiota squarrosa is quite a common mushroom here. Its determination is not difficult because of its typical habit and characteristic scales all over it. Yet, mistakes are not impossible since at least three other very similar species of this genus grow in Slovenia - Pholiota aurivella, Pholiota adiposa and Pholiota jahinii (Ref.1.) Pholiota aurivella grows on Salix and is only somewhat viscid or dry while Pholiota squarosa is always dry, without slime. Pholiota adiposa has a strongly glutinous, lustrous pileus with thin scales (Ref.:7) and Pholiota jahinii is also slimy and grows only on decayed broadleaved wood (Ref.:1).Ref.: (1) Personal communication (conf.) with Mr. Bojan Rot, www.gobenabovskem.si(2) D.
