title: Chaenothecopsis khayensis, a new resinicolous calicioid fungus on African mahogany.
abstract: The new species Chaenothecopsis khayensis (Ascomycota, Mycocaliciaceae) is described from Ghana, western Africa, on the resin of Khaya anthotheca and K. ivorensis. The species is distinctive in forming asci without crosiers and in possessing ascospores that are faintly longitudinally striate. Analysis of large subunit rDNA gene sequences positioned this species within a clade corresponding to the Mycocaliciales and identified its closest relative as Sphinctrina leucopoda. Chaenothecopsis khayensis occurs commonly on resin exuding from trees damaged by the larvae of the mahogany shoot borer (Hypsipyla sp.), and we discuss the possible ecological relationship between the fungus and these moths.
