ABSTRACT
From an exhaustive taxonomic survey of Xylariales carried out in the subtropical
montane forest of the Argentine northwest (“Las Yungas”), a first comprehensive
revision of Camillea for the country is presented. Based on a new combination of sexual
and asexual morphology, C. hladkiae and C. romeroae are proposed as new species for
the genus; C. hladkiae is principally distinguished by its conidiogenous structure from
similar species such as C. guzmanii and C. magnifica. On the other hand, C. romeroae is
mainly differentiated from other known species of Camillea by the ornamentation of the
ascospores under SEM. Additionally, the conidiogenous structure of C. coroniformis, C. flosculosa,
C. hainesii, C. hyalospora and C. signata are described and illustrated for the first
time. Furthermore, four species reports are new for the Southern Cone of South America
(C. coroniformis, C. hainesii, C. hyalospora and C. signata) and three are a novelty for
Argentine Yunga (C. flosculosa, C. obularia and C. punctulata). Finally, full descriptions,
illustrations of all species and a dichotomous key to the identification of Camillea species
for the region are provided
