Description

Apotecia 0.5-2 cm diám., stipitate, initially cylindrical, with a pruinose, yellow or cream surface, then, shell-like or infundifubiform, pinkish brown and with a central depression that perforates the stipe. Outside concolorous or slightly darker, furfuraceous, with small reddish brown warts. Hymenium yellowish and becoming brown upon maturation, initially smooth, then with lumps that sometimes break up. Stipe up to 1 × 0.5 cm, furfuraceous and concolorous with the rest of the apothecium.

Ascospores 14.5-17.4 × 7.1-8.5 µm, Q = 1.8-2.2, n = 45 (measured from a spore prints and applying a 95% threshold of Gaussian Normal Distribution), ellipsoid to fusoid, hyaline, with small guttules, furnished with very fine warts that appear to be connected forming small ridges sometimes. Asci 200-240 × 10.5-12 μm, cylindrical, pleurorrhyncous, containing 8 uniseriate spores, amyloid, with a faint bluing in the walls in IKI. Paraphyses 4-6 μm broad, filiform, septate, with brown content, more abundant towards the apex, which is slightly broader and bent. Medullary excipulum formed by globose cells of up to 70 µm diam., interwoven with small pyriform and cylindrical hyphae 7-17 µm broad. Ectal excipulum similar to the medullary excipulum, with smaller cellsand with parietal reddish brown pigment. Hairs up to 260 × 5-9 µm, cylindrical, hyaline to slightly pale yellow, sometimes formed or branched, almost straight near the margin, sinuous and sometimes entangled in the rest of the apothecial outside.

Ecology and distribution: Rare or poorly cited species that occurs on remants of Sphagnum. A report from the Netherlands was made on commercial turf from Letonia, composed of Sphagnum balticum. Up to now L. hispida has been found twice in Spain, namely in La Rioja (Martínez-Gil et al. 2017) and in León in a peatbog located at 1300 masl (Rubio et al. 2019).
