Phanerosorus satmentosus, a member of the Matoniaceae that lives on limestone cliffs – the higher the better it seems. We were lucky to spot one individual that was just about collecting height, with the help of a swiss army knife at the end of a long pole. Like Matonia, its sori consists of 6-8 sporangia arranged in a circle and under a peltate indusium. It also has a polycyclic solenostele and a rhizome covered with hairs. But the branching pattern of its fronds is reminiscent of the Gleicheniaceae, with resting buds and pseudo-dichotomous branching.
