| Description： |
Ascomata globose to turbinate, 350-470 μm in diam., ostiole periphysate with a flattened apex, yellow to red, rough, collabent when dry, gregarious and occasionally laterally confluent on an underlying erumpent to superficial, pulvinate stroma of the same color and texture as the ascomata. The anamorph, Tubercularia lateria, of a characteristic capitate shape and always associated with the teleomorph. Peridium of three regions, continuous and intergrating into the underlying stroma, 60-100 μm wide, the outer region of globose to angular, yellow, thick-walled cells, the middle of elongated, hyaline, thin-walled cells, which in some cases are strongly compressed and agglutinated at the upper half, delimitation between middle and inner wall ambiguous. Region between outer and middle wall around the ostiole sometimes showing separation and gelatinization. Apical paraphyses extending from the sides below the ostiole and growing downwards, evanescent when mature and visible as gelatinous strands. Asci unitunicate, elliptical to ovoid, widest in the middle, 70-90 × 15-20 μm, 8-spored, with a sessile to short stipe up to 12 μm long. Ascospores oblong to broadly clavate, variable in length, 20-40 × 8-11 μm, hyaline, partly biseriate, muriform, 6-9 transversely septate, with one or rarely two longitudinal septum in most of the cells. |
