Fungi on Juncus roemerianus. 10. A new Orbilia with ingoldian anamorph

Abstract

Orbilia junci sp. nov., belonging to the subgenus Hemiorbilia, is described from the endemic halophyte Juncus roemerianus from North Carolina. This small discomycete grows on the brittle tips of old standing leaves, where it is exposed to extreme climatic conditions, including drought, soaking by rain or dew, freezing in the winter, high summer temperatures and salt spray. The species forms a staurosporous hyphomycete in culture, Dwayaangam junci sp. nov., characterized by conidia that are branched dichotomously twice at the apex and consist of a cylindric-ellipsoidal main axis and four curved and tapering side arms that are pointing upwards and downwards. The new anamorph is compared with the other six species assigned previously to Dwayaangam and is the first member of this genus to be linked with a teleomorph.
