Tossol is a Catalán word (hillock) used to refer to protuberances that form in lava[1]flows and that when the lava cools become small hills. In the Jordà beech forest (in the Garrotxa Volcanic Zone Natural Park, in Catalonia, Spain) there are more than 50 tossols (spatter cones) formed by the interaction between lava flows and pre-existing wetlands that, when covered by lava at more than 1000 °C, boiled with large bubbles that raised and deformed the flow forming the tossols.[2] These in the Garrotxa Volcanic Zone are found in three lava flows, that of the Croscat volcano (Jordà beech forest), that of the Puig Jordà volcano (Tosca Forest), that of the Montolivet volcano (Pla de Dalt) and the lava flow located in La Moixina and the Parc Nou in Olot.[3]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
