Cladonia sulphurina #

Taxon #

Cladonia sulphurina

Organization #

Cladonia spp.

Identification #

Farinose-sorediate, rarely producing red apothecia. Sulphur-yellow in sunny sites, light green in the shade. Similar to C. deformis but less slender, more erratic (counterintuitive to the epithets), more perforated podetia; with an almost deflating appearance. The UV fluorescence can easily separate the two if field ID is difficult.

Substrate #

Terricolous, on humus, lignicolous (Brodo et al. 2001)

Chemical Tests #

K-, C-, KC- or KC+ yellow, Pd-, UV+ white (CLH, Brodo et al. 2001)
