Nomenclature
-
Family: BionectriaceaeGenus: Hydropisphaera
SUMMARY
Anamorph: not known.
Teleomorph: stromata absent. Ascomata perithecia, 90-130 µm diam and 120-150 µm high (measurements from rehydrated specimen), scattered, globose to pyriform, bright orange, superficial. Cells on the surface of the ascoma globose to angular, 5-8 µm diam, rather refractive and forming short clavate projections; merging into textura intricata at the base. Ascomatal wall ca 10 µm thick, with an inner region of elongate cells; the ostiole with well-developed apical paraphyses. Interascal tissue absent. Asci 80-90 x 9-10 µm, clavate, fairly short-stalked, the apex obtuse and lacking a ring, 8-spored. Ascospores biseriately arranged, (15.2-) 17-21.8 [mean 18.9] x 3.8-4.8 [mean 4.3] µm, narrowly fusiform-ellipsoidal, with a median to slightly submedian septum which develops rather late in the ontogenetic process, sometimes slightly curved, hyaline, without a gelatinous sheath or appendages.
