Pseudoboubovia benkertii (Perić) U. Lindem., M. Vega, Perić & R. Tena, Z. Mykol., 81 (2): 392 (2015).

Basionym Kotlabaea benkertii Perić, Mycol. Monten., 15: 15 (2013).

Diagnosis Apothecia 1−8 mm in diam., sessile, gregarious, rarely scattered; hemispherical, expanding when it grows, becoming slightly concave or like a button and finishing with an irregular shape; margin regular, raised, smooth or finely serrated, or irregularly wavy or incurved, forming smaller or larger irregular lobes, always concolorous with hymenium. Hymenium smooth, moist, shiny, yellow orange, lemon yellow, greenish yellow, but light yellow to off-white when apothecia develop under layer of needles. Excipulum smooth, slightly granulated (loupe), concolorous with hymenium. Asci cylindrical 250−300 × (10−)13-16(−18) μm, †(220−275 × 10−13 μm), J−, without crozier. Ascospores 14,5−18,5(−19) × 8,5−10,5 μm, ellipsoid, ovoid, rhomboid or eccentric, thick walled, hyaline or occasionally pale yellowish, cyanophyilic, containing dense droplets of equal sized 1−2,5(−3) μm in diam., but while some are uniguttulate, some are biguttulate. Paraphyses filiform, thin, with no extension at apices but distinctly curved, densely septate, usually slightly extended near septa, containing yellow or orange guttules, which do not stain green with iodine, branched along entire length, anastomosed, apices deform when they grow old. Medullary excipulum of textura intricata, of elongated hyphae 23−36 × 3−5 μm mixed with similar but thickened hyphae 15−40 × 4−13,5 μm in diam.. Ectal excipulum of textura globulosa of spherical cells 7−20 μm in diam., mixed with swollen hyphae, 18−30 × 13−23 μm in diam.. Hairs as anchor hyphae cover base of apothecia going deep into substrate, single or fasciculate, arise from spherical excipular cells, hyaline or pale yellowish, septate, anastomosed, thick walled, blunt tips, 720 μm long, 2,5−6 μm wide. Carotenoid pigment presents almost everywhere, including cells that compose hymenium and excipulum, but also paraphyses, especially in tips.
Habitat: grows on bare sandy soil near beaten path, among moss, in coniferous forest, on needles and cones of Pinus halepensis and Cupressus sempervirens, on surface or in litter.
