Pseudothielavia terricola

About

Pseudothielavia terricola is a fungal species of the phylum Ascomycota, family Chaetomiaceae, and genus Pseudothielavia. Pseudothielavia terricola is widely distributed, especially in the tropical region of the world – with documented appearances in Africa, Southern Europe, and Asia. The species is mainly found in soil, but can also be found on other materials such as animal dung. The species was first assigned to the genus Coniothyrium in 1927, but was soon re-assigned to the genus Thielavia which endured for almost 90 years. Through intensive phylogenetic research and reassessment, the species was designated to a new genus, Pseudothielavia; the etymology of Pseudothielavia means similar to the genus Thielavia – the high resemblance was what contributed to the species assignment to the genus Thielavia nine decades ago. The fungus is mesophilic, grows abundantly in a pH level between 3.9–6, and is able to utilize multiple carbohydrates to support its growth. Mature Pseudothielavia terricola colonies in culture is dark brown in colour and spread out. Pseudothielavia terricola synthesizes a variety of compounds, two of which are thielavin A & B. These compounds were determined to be strong inhibitors of prostaglandin synthesis.
