Lobaria scrobiculata, commonly known as the textured lungwort, is a large foliose, epiphytic lichen.
The thallus of L. scobiculata has broad, concave and rounded lobes, rather wider than in Lobaria pulmonaria. The upper surface has large shallow depressions (scrobiculate, hence the specific name). Blue-grey soredia, the asexual reproductive bodies, are always present along ridges and on the margins. The thallus has a blue-grey colour and pliable texture when hydrated but assumes a light grey or yellow-grey colour and papery texture when dehydrated. The underside is covered by light brown tomentum and rhizines except on raised areas that correspond to the depressions on the upper surface. Fungal fruit bodies (ascocarps), rarely present, are small dark red discs with a thick inflexed margin. Thallus lobes grow away from the substrate in irregular patches as in L. pulmonaria but unlike the more regular rounded and flattened colonies of L. quercizans, L. amplissima and L. virens. The algal symbiont is the cyanobacterium , in contrast to the green algae in most other species of Lobaria.
