Catillaria gilbertii is a rare species of saxicolous (rock-dwelling), crustose lichen in the family Catillariaceae. [1] It is found in the Central Highlands of Scotland.
The lichen was formally described as a new species in 1996 by lichenologists Alan Fryday and Brian Coppins. The type specimen was collected by the first author from the Ben Lawers National Nature Reserve ( Perthshire) at an altitude of 890 m (2,920 ft); there, it was found growing on an east-facing mica-schist rock face. The species epithet was named to honour British lichenologist Oliver Gilbert "for his pioneering work on the montane lichen vegetation of the British Isles". [2] They noted that the naming of this species, which produces twice the usual number of ascospores in its asci, was "particularly appropriate given the pre-disposition of the Gilbert family for producing twice the usual number of offspring at a time; Dr Gilbert himself is a twin and he also has twin daughters". [2]
The lichen has dark-brown to dark grey thallus that is bluish-grey when wet. It is areolate (with individual areoles measuring about 0.15–0.27 mm in diameter), cracked, and effuse. Its apothecia are dark brown to black with a lecideine form and a diameter between 0.3–0.7 mm; there is a slightly raised proper margin (width of 0.04–0.1 mm) surrounding the flat or slightly convex disc. Its ascospores are hyaline with an oblong to ellipsoid shape and a single septum, and measure 10–12 by 2.5–3 μm. The spores typically number 16 per ascus, which itself is of the Catillaria-type—with a uniformly amyloid dome at the apex. Immersed in the thallus surface are conidiomata in the form of pycnidia; they are 60–80 μm in diameter and produce conidia that are ellipsoid to ovoid with dimensions of 2.5–3 by 0.8–1.4 μm. [2]
All parts of Catillaria gilbertii do not react with any of the standard chemical spot tests used to test for the presence of lichen products. [2]
Catillaria gilbertii is only known to occur in the mica-schist mountains of the Scottish Central Highlands. In addition to the type locality, it has also been recorded in Glen Esk in Angus. [2] It is one of relatively few endemic lichens known in Scotland, and one of even fewer that inhabit the hyper-oceanic mountain habitat, above the tree line. [3] Two similar species that occur in the same habitat are Catillaria chlybeia and Halecania rhypodiza. [2]
