Talarómyces pinóphilus(lat.) - a species ofimperfect mushrooms (the teleomorphic stage is unknown), belonging to the genus Talaromyces ( Talaromyces ). Previously included in the genus Penicillium ( Penicillium ) as Penicillium pinophilum .
Colonies on CYA on the 7th day were 1.8–2.5 cm in diameter, with white, yellow and orange mycelium, raised in the center, friable-beam, with sparse to moderate sporulation in gray-green or dull green colors. Exudate is present in the form of small colorless and reddish droplets. Soluble pigment is not secreted, less often, yellow. The reverse of the colonies is grayish-orange in the center to yellow along the edges.
On malt extract agar (MEA), colonies with white, yellow and red mycelium, in the center are slightly raised, frizzy-bunched. Sporulation is sparse to plentiful, gray-green or dull green. The reverse is brown-orange. Soluble pigment is not released into the medium.
On agar with yeast extract and sucrose (YES), the colonies in the center are slightly raised, with white and yellow, sometimes also with red mycelium, woolly, with a sparse to moderate gray-green spore. Soluble pigment does not stand out, the reverse of the colonies is yellow-orange or red-brown in the center, and yellow closer to the edge.
Conidiophores are two-tiered brushes with a smooth-walled leg 30-200 microns long and 2-3 microns thick. Metulae in a whorl of 3-8, diverging, 10-11 microns in length. Needle -shaped phialides, 3-8 in a bundle, 8.5-12 × 2-3 microns. Conidia are spherical or almost spherical, smooth-walled, 2-3 microns in diameter.
Differences from close species
The closest species is Talaromyces sayulitensis , which is characterized by a slightly faster growth (the diameter of the colonies on CYA on the 7th day often exceeds 2.5 cm) and molecular characteristics. Talaromyces aculeatus and Talaromyces verruculosus are distinguished by flask-like phialides and spherical rough conidia. Talaromyces stollii is characterized by faster growth. Talaromyces amestolkiae is distinguished by the red color of the reverse of the colonies and the formation of black sclerotia. Talaromyces angelicus does not secrete acids on creatine-sucrose agar (CREA).
Ecology
Mostly soil fungus, rarely found as a pollutant on various organic substrates.
