Phaeobotrys gen. nov., based on Phaeodactylium acutisporum, characterized by branched and pigmented conidiophores, and the production of hyaline, appendiculate conidia from denticles on polyblastic conidiogenous cells which usually extend sympodially to form more conidiogenous loci, and Zanclospora stellata sp. nov., recognized by its stellate sterile branches in the distal part of the conidiophore and bacilliform conidia, are described and illustrated from decaying leaf litter from Nigeria. Keys to Phaeobotrys and related genera, and to species of Zanclospora are proposed. Furthermore, a list of hyphomycetes newly reported for Nigeria is provided.

Natural products from Nigerian plants are significant in the search for drug compounds, as they contribute new compounds with biological properties to the fight against resistant pathogens, hence the study. Fresh leaves of were prepared for fungal isolation, identification, fermentation, and secondary metabolites extraction. The extract, subjected to HPLC analysis revealed the presence of two bioactive compounds: p-Hydroxylbenzoic acid, and Protocatechuic acid.

Pigeon droppings are among the major environmental sources of AFLP1/VNI from where the organism infects susceptible humans and animals resulting in cryptococcosis. Until now, AFLP1B/VNII was the only molecular type reported in Nigeria. Effective clinical treatment of this infection has occasionally been stymied by the emergence of antifungal non-susceptible, and resistant strains of AFLP1/VNI.

Infestation of food crops by fungi has led to serious economic losses in the international market. There is a paucity of information on the multi-mycotoxin profile of cashew nuts from different geographical locations in Nigeria and South Africa. This work aims at comparing the fungal metabolite profile of cashew nut from two African countries using HPLC-FLD and LC-MS/MS.
