Cryptovalsoidea, referring to the morphological similitude of this fungus with Cryptovalsa. Stromata plerumque in cortice, male evoluta circa fundum perithecialem, nigra, effusa atque paulo callosiora circa cervices peritheciales sub peridermio. Perithecia plus minus inter se coniuncta et ad copiosos coetus congruentia, inaequabiliter constratos. Ostiola hemisphaerica, saepe perforata,

singula buy CHIR-99021 vel coniunctim per corticem eminentia. Asci clavati vel fusiformes, longe pedicellati, polyspori, parte sporifera 65–120 × 15–20 μm. Ascosporae flavidae, in corpore aquiliorae, OICR-9429 cell line allantoideae vel sub-allantiodeae, 8–12(−13.5) × 2–3 μm. Coloniae albae cum subexcelso mycelio tenuique areo-roseo inferiore. Conidia non evidentia. Stromata mostly in bark, poorly developed around the perithecial base, black, effuse and rather crusty around perithecial necks below the periderm; perithecia more or less in contact and confluent into large groups, irregularly scattered; ostioles hemispherical, often perforated, Selleck Cobimetinib emerging singly or in groups through bark. Asci clavate to spindle-shape, long-pedicellate, polysporous, p. sp. 65–120 × 15–20 μm. Ascospores yellowish, darker in mass, allaintoid

to sub-allaintoid, 8–12(−13.5) × 2–3 μm. Colonies white Fossariinae with rather moderate aerial mycelium and slight orange-pink underside. Conidia not seen. Hosts. Ficus carica (Australia, NSW). Notes. The present species displays some features of morphology typical of Cryptovalsa (poorly developed stroma, polysporous ascus) as well as Eutypella (perithecial necks erumpent in groups). Because of the polyporous ascus, this species could be referred as Cryptovalsa under the current classification scheme for Diatrypaceae. However, size and shape of the polysporous asci differed from all Cryptovalsa species previously described from Ficus carica and additional host plants.
