were very narrow, so probably is P. hirsuta (I can’t give precise dimensions). Moreover, this species appears in the portuguese checklist. Thanks, Jason.

Nice! One of the hairy ones…

British Flora doesn’t have any with hairs on the upper surface. In North America we have P. hirsuta and P. kairamoi. There’s also P. cernohorskyi but Esslinger synonmized it with P. hirsuta. The difference between these two is: hirsuta is narrower (0.5-1mm) and (usually) lacks hairs in the soredia; kairamoi is broader (1-2mm) and always has hairs among the soredia.
