The paper deals with the development of ascocarp and nuclear behaviour during the development of ascus and ascospores in Achaetomium uniapiculatum. The ascocarp arises by the coiling of a hyphal branch.The septate ascogonial coil soon becomes surrounded by the vegetative hyphae forming a pseudoparenchymatous spherical body which in later stages gets differentiated into wall layers and central sporogenous tissue. The ascus originates from the penultimate cell of the crozier produced by the binucleate ascogenous cells. As in most of the ascomycetes, in A. uniapiculatum also, four divisions follow karyogamy resulting in binucleate ascospores, each mature ascospore only has a single nucleus the other nucleus probably degenerates.The haploid number of chromosome is 5 (n=5).
