Spathularia flavida

Species associated with montane conifers, with spatula-shaped ascomata, small in size, 2 to 5 cm high, lemon yellow, of gelatinous and pliable texture.

Excipulum formed by cylindrical, hyaline hyphae 6 to 18 µm wide, interwoven with more slender connective hyphae 2 to 5 µm wide.

Asci clavate to fusiform, eight-spored, 80 to 120 µm long, 9 to 14 µm wide, with parallel to fasciculate spore arrangement within the ascus, and inamyloid in Melzer's reagent (negative reaction).

Paraphyses filiform, septate, hyaline, 1.5 to 3 µm wide, without apical enlargements, branched, with curved, twisted or even coiled apices, slightly exceeding the height of the asci.

Ascospores filiform, with one pointed end and the opposite end rounded, hyaline, thin-walled, 50 to 65 µm long, 2.5 to 4 µm wide, with transverse septa appearing upon maturity, containing small refringent oil droplets of varying size inside.
