*Description based on living material

Ascomata solitary or gregarious in small groups. Apothecia 0.5-1.5 mm diam., plane to slightly concave, hymenium greyish white to ochre-cream, sometimes brown, variable depending on the hydration degree, with a raised margin. Outer surface darker than the hymenium, covered with dark brown hairs similar to those from the margin. Stipe well-delimited, narrowly obconical, of up to 1.5 mm high, of the same colour as the outer surface of the apothecia, except for the base which is reddish brown, hairy, especially on the upper half. Apothecial base producing a stromatized zone on the substrate.

Medullary excipulum of textura intricata, with hyaline cells, 30-45 × 10-15 µm, of textura prismatica-porrecta towards the stipe. Ectal excipulum of textura intricata, composed of pale brown hyphae, slightly gelatinous, with clavate endings in the margin. Marginal hairs acuminate, brown, sometimes with a paler apex, straight, acute, multiseptate (15-20 septa), thick-walled (up to 3 µm), with a simple and broader base, sometimes bulbous, de (235-)319-443 × (10-)16-24.5(-26.3) µm, towards the apothecial base with numerous shorter, cylindrical to claviform hairs. External hairs similar to those from the margin, slightly shorter. Asci clavate, curved, 8-spored, usually with obliquely arranged spores (looking biseriate), with an amyloid (BB) apical pore, aporrhynchous, with a narrow appendix that looks an incomplete crozier, (127-)130-151(-155) × 13-15.5 µm. Ascospores allantoid, with obtuse poles, falciform to half-moon-like, usually with 2 or 3 guttules surrounded by smaller ones, with a central nucleus, with a gelatinous sheath that is detached sometimes, aseptate, (-15)18-23.9 (-25.4) × (-5.2)5.5-6.4(-7) µm, Q=(3.10-) 3.28-4.33(-4.39), Qm=3,6. Paraphyses straight to slightly curved towards their apex, with a broader apex (up to 5.7 µm), with large vacuolar bodies (VBs), elongated in upper segments and with small guttules in other segments. Subhymenium pale brown.

Habitat and distribution: Torrendiella ciliata occurs typically on fallen sclerophyllous leaves of several species of Quercus, mainly Q. coccifera, Q. rotundifolia and Q. suber and appears to avoid areas of continental climate. It is known from scattered localities from the periphery of the Iberian Peninsula, and has been also found in the Canary Islands (Tenerife, Gomera; Galán et al. 1993). Nevertheless, there exist finds on leaves of Quercus rubra (ARAN-Fungi A3022450), twigs of Castanea sativa (Merino 2014) in the Iberian Peninsula, and also on Rubus elsewhere in other areas from Europe (Johnston et al. 2014). The material from the Canary Islands, reported by Galán et al. (1993), was collected in Laurus and would deserved future studies to confirm that they are specific with collections on Fagaceae.
