Abstract

Abstract Eight species of euantennariaceous sooty moulds are distinguished in about 250 collections from New Zealand. Four species are described and illustrated with Euantennaria ascostromata, and Antennatula and Hormisciomyces imperfect states; these are E. mucronata (Moet.) Hughes, E. novae-zelandiae nsp., E. pacifica nsp., and E. caulicola n.sp. Four new species of Antennatula are described and illustrated; these are A. triseptata n.sp., A. fisherae n.sp., A. dingleyae n.sp., and A. fraserae n.sp. A. fisherae and A. dingleyae also produce a Hormisciomyces phialidic state. The two original species of Aithalomyces Woronichin are induded in Euantennaria as E. arctica (Woronichin) n.comb. and E. rhododendri (Woronichin) n.comb. Both species are illustrated and described. Limacinia alaskensis Sacc. & Scalia is considered to be a possible earlier synonym of E. rhododendri. Brief notes are given on E. tropicicola, the type species of this genus, and Hormisciella rubi Bat. is considered a possible name for its Antennatula state, and Hormisciomyces prepusum Bat. & Nasc. and H. bellum Bat. & Carn. are possible names for the Hormisciomyces state. Napicladium fumago Speg. is based on Antennatula conidia.
