Gyalectidium kenyanum

The thallus forms rounded patches about 1–3 mm across. The thallus comprises small, blister-like segments (areolate-bullate) and is heavily covered with a continuous layer of crystals, giving it a silvery to whitish-grey appearance.^[2]

Hyphophores (asexual reproductive structures) are produced on the thallus surface and are immersed in it; usually 1–3 occur per thallus patch. Each hyphophore forms a small, rounded depression about 0.15–0.2 mm in diameter. From the rim of the depression, the hyphophore "scale" is divided into narrowly triangular to bristle-like segments that point inward toward the centre; the segments are about 0.1–0.2 mm long and 10–20 μm broad. The segments are whitish, and the diahyphal mass (the underlying reproductive fungal tissue) is greyish. Apothecia (fruiting bodies) are rare but present. They are angular-rounded, about 0.15–0.25 mm in diameter, with a pale yellowish-brown to greyish disc that can be thinly pruinose and a whitish margin. The ascospores are oblong-ellipsoid, measuring 30–50×10–15 μm. Pycnidia were not reported.^[2]

This species is known only from the type locality in Kenya, where it was collected in montane rainforest at about 2,100 m elevation. It was reported from the same locality as Gyalectidium atrosquamulatum.^[2] In a 2002 survey of leaf-dwelling lichens in Kenya, Gyalectidium kenyanum was one of six Gyalectidium species known to occur in the country.^[3]
