New multi-ascosporic capnodiaceous fungus from the Cerrado.
A capnodiaceous ascomycete belonging in a new genus was found in the Brazilian Cerrado, and characterized by: colonies effuse, epiphyllous, superficial; mycelium superficial, light brown to brown; hyphae septate, branched, light brown; hyphal cells cylindrical [9-17 (12) × 2-5 (3) μm] or monilioid [9-19 (12) × 4-6 (4) μm]; ascomata 109-198 (140) μm diam., ostiolate, globose or ovoid, superficial, unilocular, smooth; wall with textura ranging from globose to angular; asci 44-69 (54) × 27-44 (31) μm, broadly clavate or obovoid, bitunicate, aparaphysate, about 64-spored; ascospores 7-10 (8) × 3-4 (3) μm, hyaline, elliptical to fusoid, 1-2-septate. None of the known genera in family Capnodiaceae could accommodate the new fungus. Thus, it will soon be described as the type species of a new monotypical genus to be published following the International Code of Botanical Nomenclature.
