Morphology and multigene phylogeny of Talaromyces amyrossmaniae, a new synnematous species belonging to the section Trachyspermi from India

A new Talaromyces species, T. amyrossmaniae, isolated from decaying fruit and litter of Terminalia bellerica, is described and illustrated. On the natural substrate, the new species produces determinate synnemata, with a well-defined, vivid orange red to orange red cylindrical stipe, and a greyish green capitulum. Conidiophores are typically biverticillate, or sometimes have subterminal branches, with acerose phialides that produce globose to subglobose, smooth to slightly roughened conidia. Multigene phylogenetic analyses based on the internal transcribed spacer region (ITS), and partial sequences of β-tubulin (BenA), calmodulin (CaM), and DNA directed RNA polymerase second large subunit (RPB2) genes, along with morphological characterization, revealed that these isolates are distinct and form a unique lineage of Talaromyces in section Trachyspermi, closely allied to T. aerius, T. albobiverticillius, T. heiheensis, T. erythromellis, and T. solicola. The new species T. amyrossmaniae is the first species in section Trachyspermi with determinate synnemata.SERB, Department of Science and Technology, Government of India.https://mycokeys.pensoft.netpm2020Forestry and Agricultural Biotechnology Institute (FABI)Microbiology and Plant Patholog

Rediscovery of Penicillium paradoxum (Ascomycete: Aspergillaceae) from Maharashtra, India

Penicillium paradoxum has an enigmatic Aspergillus-like anamorphic state; earlier named as Aspergillus paradoxus with a teleomorph state Hemicarpenteles paradoxus.  The present paper describes the rediscovery of this species from India after five decades and includes a phylogenetic study of this strain.  This is the first record of this strain from peninsular India including the Western Ghats. </div
