New Species of Talaromyces (Trichocomaceae, Eurotiales) from Southwestern China

Abstract

Species of Talaromyces are cosmopolitan and ubiquitous, and some are of industrial and medicinal importance. Species of Talaromyces have been successively reported in China. During our examinations of samples collected from southwestern China, two new species belonging to Talaromyces sect. Talaromyces were further discovered based on phylogenetic analyses and morphological comparisons. Talaromyces ginkgonis sp. nov., isolated from a partially colonized fruit of Ginkgo biloba, differs from closely-related fungi in the combination of conidia ellipsoidal, smooth and 3.5−4 × 2−3 μm, no growth on CYA at 37 °C and sequence divergences; T. shilinensis sp. nov. is distinguished from its related allies in the combination of smooth conidia, colonies 10−11 mm diameter on CYA at 25 °C and sequence differences. Detailed descriptions and illustrations of the new taxa are given.

Talaromyces santanderensis: A New Cadmium-Tolerant Fungus from Cacao Soils in Colombia

“…T. santanderensis is the fifth species from the Talaromyces sect. Talaromyces described from type material from Colombia, after T. amazonensis , T. francoae , T. purgamentorum, and T. veerkampii [ 29 , 49 ]. Recently, the number of Talaromyces species has increased [ 49 ], but further studies are needed to understand the entire biodiversity of the group in Colombia.…”

“…To date, Talaromyces contains more than 250 described species in the Mycobank database [ 28 ] and Talaromyces section (sect.). Talaromyces contains roughly 86 species [ 29 ]. Additionally, inside the Talaromyces sect.…”

“…Additionally, inside the Talaromyces sect. Talaromyces is located the informal group Talaromyces pinophilus complex, which harbors T. lentulus, T. mae, T. soli, T. malicola, T. adpressus, T. annesophiae, and T. pratensis [ 29 , 30 ]. However, this complex requires improved phylogenetic elucidation to further support this subgroup species’ evolutionary relationships.…”

Antagonistic effects of Talaromyces muroii TM28 against Fusarium crown rot of wheat caused by Fusarium pseudograminearum

“…Thus, the genus Penicillium has been redefined as Penicillium sensu stricto and Talaromyces ( Chen et al, 2016 ). Talaromyces originated from the ocean and now resides as endophytes in air, soil, decaying food, and healthy plants ( Wang and Zhuang, 2022 ). Studies have shown that Talaromyces and its secondary metabolites can exhibit antibacterial, antifungal, and antitumor activities ( Rateb and Ebel, 2011 ), which is of great value for further research ( Zhao et al, 2022 ).…”

A New Species and Five New Records of Talaromyces ( Eurotiales , Aspergillaceae ) Belonging to Section Talaromyces in Korea

“…Species of section Talaromyces are commonly isolated from soil, indoor environments, food products, and leaf litter; they are also present in association with the ascomata of Pseudocosmospora sp. on rotten twigs of ginkgo ( Ginkgo biloba L.) [ 2 , 6 , 11–15 ]. Some species have clinical, ecological, and industrial importance [ 14 , 16 ].…”
