Myriangium duriaei

Specimen examined: Argentina, Delta del Paraná, on Chrysomphalus aonidium, 23 July 1934, L. Godsinsky, CBS 260.36.

The genus Myriangium (Myrangiales, Dothideomycetes) is based on the type species M. duriaei. The genus is associated with scale insects or resinous exudates, and is presumably parasitic. It is widely distributed on many kinds of scale insects in the tropics.

Myriangium is characterized by having erumpent, black stromata, crustose or pulvinate, composed on thin, brown, pseudoparenchymatous tissue, containing ascomatal locules that each have an ascus. Asci globose to obovate, 8-spored, sessile, fissitunicate, with poorly defined ocular chamber. Ascospores hyaline, smooth, muriformly septate, frequently constricted at septa.
