Extract from Wikipedia article: Aspergillus alliaceus is a species of fungus in the genus Aspergillus. It is from the Flavi section. It was first described scientifically by Charles Thom and Margaret Church in 1926. Its associated teleomorph is Petromyces alliaceus. It has yellow spores.
Aspergillus alliaceus is a species of fungus in the genus Aspergillus, family Trichocomaceae, order Eurotiales, class Eurotiomycetes, phylum Ascomycota. It is characterized by its yellow-green to brownish-colored colonies and globose to subglobose conidia. In East and Central Texas, A. alliaceus has been isolated from soil and plant debris, with reports of its presence in areas with alkaline soils and dry environments. The fungus produces mycotoxins, including chaetomin and aspergillic acid, and has been associated with spoilage of grains and other organic materials.

Pad decay fungus Aspergillus alliaceus(?) (black) on prickly pear cactus (Opuntia) on Kiwanis Nature Trail. College Station, Texas, December 20, 2017Kiwanis Nature Trail, College Station, Brazos County, Texas, 77843, United StatesObservations of the fungus Aspergillus alliaceus in East and Central Texas reveal its presence on prickly pear cacti (Opuntia). On Kiwanis Nature Trail in College Station, Texas, the fungus was found on warped pads of the cactus, causing cladode rot. The affected areas turned black, indicating the presence of Aspergillus alliaceus. Similar observations were made on December 20, 2017, where pad decay fungus, identified as Aspergillus alliaceus, was seen on prickly pear cacti along the same trail. These findings suggest that Aspergillus alliaceus is a common pathogen affecting Opuntia species in this region, causing rot and decay on the cactus pads. The fungus appears to thrive in the local environment, potentially impacting the health and survival of the prickly pear cacti in East and Central Texas. Further observations are needed to confirm its distribution and impact.
