Microglossum clavatum
V.Kučera, Lizoň & Tomšovský

Study description
General: Earth tongue (geoglossaceous fungus), clavate, growing among moss and leaf litter in humid woodlands, bright bluish-green, upper fertile portion distinct from the lower sterile stipe.
Excipulum: Medullary excipulum of compact, filamentous hyphae of textura intricata mixed with short polygonal cells, transitioning to a thin layer of textura porrecta; ectal excipulum poorly differentiated, of textura angularis.
Asci: Cylindrical to clavate, 8-spored, 110-150 x 9-10.5 µm, spores biseriate to irregular, apical apparatus amyloid in Melzer's reagent or Lugol's.
Paraphyses: Filiform, smooth, hyaline, 1.5-2 µm wide, apices slightly swollen up to 3 µm, branched from the base, not projecting beyond asci.
Ascospores: Ellipsoid to fusiform, some slightly allantoid, unicellular, asymmetric, smooth, hyaline, thin-walled, 14-21 x 5-6 µm, containing lipid guttules.
Herbarium voucher: JTP2739/26.
