New Species of Termitaria (Termitariales, Deuteromycetes) on Australian Termites (Isoptera)

Abstract
Species of Termitaria are external parasites of a number of genera of termites, forming discoid to ellipsoid lesions on the exoskeleton and sending haustoria into the integument. There are only 2 validly published species, T. snyderi and T. coronata. This report describes 3 new species [T. macrospora sp. nov., T. rhombicarpa sp. nov., T. longiphialidis sp. nov.] found on the genera Coptotermes, Mastotermes and Porotermes (the first two are previously unreported hosts) and includes records of T. coronata on 2 additional species of Nasutitermes. This also represents the 1st report of Termitaria in Australia. The new species of Termitaria differ from previously described species in the number of spores per phialide, spore size and shape, pigmentation of the conidiogenous zone, morphology and branching of haustoria, and overall thallus dimensions.
