Another sterile Cladonia sp. living among mosses and other cladonia species, under the shadow of a fence in the field. There were several cushions like the one in the first photo (measuring 7.5 cm wide, so that the squamules are of 2-3 mm wide) all of them steriles. The C+ green reaction lead me to C. strepsilis_, according to the key presented in Lendemer and Hodkinson. On the other hand, in lastdragonstrepsilis.html this C+ green (said to be emerald) reaction is also mentioned and the color of the squamules is described as "typically pale bronze-green above, white beneath", which I think is the case of this specimen (see the left-center of the first photo). However, none of the above references refers the K+ yellow-red-brown reaction, which I think reveals the presence of fumarprotocetraric acid. Therefore, I'm not secure that it is C. strepsilis and maybe is another usually sterile species.
