Orbilia inflatula (P. Karst.) P. Karst., Notiser ur Sällskapets pro Fauna et Flora Fennica Forhändlingar 11: 248. 1870.

 Description: Apothecia scattered, superficial, subsessile, smooth. Disc up to 1.5 mm, usually 0.5-1 mm across, flat or concave when moist, margin even, pallid, yellowish white when dried. Receptacle thin, cupulate to discoid, smooth, centrally attached, usually with white basal anchoring hyphae, like a rudimentary but quite conspicious subiculum. Asci 8-spored, (19.6-)22.5-26.5(-31.4) × 2.0-2.3 μm, cylindric-clavate, apex broadly rounded, J–. Ascospores (4.9-)5.9-6.9 × 0.8-1.0 μm, hyaline, cylindric, slightly broader towards the apical end, straight or very slightly curved, nonseptate, biseriate or disposed in 3 series within the ascus. Paraphyses enlarged at tip, but not markedly knob-headed as in most species, hyaline, ercusted and immersed in an epithecium at the apex. Subhymenium composed of thin walled, hyaline hyphae. Medullary excipulum thin, composed of narrow, septate, intricated hyphae. Ectal excipulum formed of angular hyaline cells with thin walls.

 Note: Both Orbilia auricolor and O. inflatula have conspicuous short white anchoring hyphae surrounded the apothecium. The ascospores of the above two species are similar with narrowly cylindric, slightly curved and broader at the apex. However, the former is easily recognized by the larger ascospores and asci with forked-base, which is not immersed in a continous epithecium.
