Distr. Ad truncos putridos praesertim in silvis et ad 

 lignum putridum supra tecta, rarius ad terram nudam locis 

 apricis et ad terram turfosam muscosque in paludibus tur- 

 fosis crescit, frequenter vel sat frequenter toto territorio 

 proveniens. „In reg. silvatica Lapponiae occid. praesertim 

 in regione coniferarum sat frequens, pluribus locis prove- 

 niens adhuc ad Kilpisjarvi" (Norrl. Ber. Torn. Lappm. p. 321), 

 sat frequenter in ceteris partibus Lapponiae Fennicae, sed 

 baud notata e reg. subalpina (Vain. Adj. Lich. Lapp. I p. 

 114), „haud rara in Lapponia Kuollaensi et adhuc ad Kuolla" 

 (N. L Fellman in Nyl. Lich. Lapp. Or. p. 110), in luco ad 

 Umpjavr in Lapponia Imandrensi (A. 0. Kairamo).

 continet, quod autem sec. Zopf (Beitr. Chem. Mon. Clad. p. Ill) 

 non differt ab acido squamatico.
