Nectriella dacrymycella  

Anamorph: not known.
Teleomorph: stromata absent. Ascomata perithecia, 180-230 µm diam and 140-200 µm high, scattered or in small clusters, subglobose, bright orange, sometimes remaining covered by host epidermis but frequently becoming erumpent, not staining in KOH. Cells on the surface of the ascoma angular, 6-10 µm diam, merging into textura intricata at the base. Ascomatal wall ca 10 µm thick, to 20 µm in the apical region as an expanded outer region of rounded, thick-walled cells, with an inner region of elongate cells; the ostiole with well-developed apical paraphyses. Interascal tissue absent. Asci 56-71 x 10-11.5 µm, clavate, short-stalked, the apex truncate with a small ring, 8-spored. Ascospores biseriately arranged, 13.6-17.3 [mean 15.7] x 3.9-5.0 [mean 4.5] (13-20 x 4-5.5 µm fide Rossman et al. 1999), fusiform-ellipsoidal, with a median to slightly submedian, sometimes slightly constricted septum which develops rather late in the ontogenetic process, sometimes slightly curved, at first hyaline but becoming pale brown, smooth or slightly rough-walled, sometimes with two guttules per cell, without a gelatinous sheath or appendages.
