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.

I love your posts! Not so long ago, I came across this genus while filing plants in the herbarium. I was fascinated by it. It is very nice to see your photos of the living thing and its habitat. Thanks!
