| Description： |
Colonies growing fast on on Potato Dextrose Agar at 25℃, grayish-green to dark green, plane, reverse brown to yellowish-brown, diffused pigment lacking. Mycelium partly immersed, composed of branched, septate, thin-walled, hyaline hyphae, 1.5 - 3.5 μm wide. Conidiophores erect, arising mostly from aerial, funiculus hyphae, smooth to finely rough, hyaline, 460 - 590 × 4 - 4.7 μm. Penicilli regularly biverticillate. Metulae hyaline, in divergent verticils of 3 - 7, 14 - 17.1 × 2.9 - 4 μm. Phialides hyaline, smooth, and thin-walled, acerose or rarely ampulliform, 3- 7 per metulae, 11.5 – 14 × 2 – 3 μm. Conidia hyaline or light green, smooth, ellipsoidal or subglobose, 3.2 - 4 × 2.9 - 3 μm, borne in loose compact chains. | |||

| Note： |
On a global view, the isolate of Penicillium radicum isolated from decaying wood from Taiwan was very similar to the species described by Hocking et al. (1998). Except the morphological resemblance, both isolates also show high sequence identity (99%) in rDNA (ITS1-5.8S-ITS2), which further support that they are conspecific, though with minor deviation in size of metulae or in length of conidiophores. | |||
