03CA29205116FFE278CBF8A2FC0EF7C0.taxon	distribution	Geographical distribution: — Known only from northern Thailand. According to GlobalFungi, the identical ITS sequences (similarity ≥ 98 %) were found in soil samples from the forest in southwestern China (Sun et al. 2021) and in shoot of seagrass [Enhalus acoroides (Linnaeus f.) Royle] in Malaysia (Wainwright et al. 2019). The sites have a tropical climate (MAT avg. 21.6 ° C, MAP avg. 1418 mm).	en	Khuna, Surapong, Kumla, Jaturong, Thitla, Tanapol, Hongsanan, Sinang, Lumyong, Saisamorn, Suwannarach, Nakarin (2023): Penicillium thailandense (Aspergillaceae, Eurotiales), a new species isolated from soil in northern Thailand.

03CA29205116FFE278CBF8A2FC0EF7C0.taxon	discussion	Note: — The colony characteristics of P. thailandense on CYAS and DG 18 at 25 ° C for one week were similar to P. sanjayi. However, P. thailandense can be distinguished from P. sanjayi by its white to dark gray sclerotia, whereas P. sanjayi has cream sclerotia (Table 3) (Ashtekar et al. 2022). In addition, the growth of P. thailandense at 25 ° C on CYA, CYAS, MEA and YES was slower than P. sanjayi (25 – 27, 30 – 39, 16 – 20 and 29 – 31 mm, respectively), but was displayed faster growth than P. sanjayi on CZA and OA (14 – 16 and 14 – 15 mm, respectively) (Ashtekar et al. 2022). While, P. thailandense on CYA at 30 ° C showed faster growth than P. sanjayi (10 – 12 mm) (Ashtekar et al. 2022). Remarkedly, P. sanjayi did not grow on CYA and MEA at 37 ° C, but P. thailandense did on both media. Based on the micromorphological characteristics, P. thailandense has both monoverticillate and biverticillate conidiophores, in contrast to P. sanjayi which is strictly monoverticillate. Moreover, P. sanjayi differs from P. thailandense by its smaller (2 – 2.5 µm) and roughened to verruculose conidia (Table 3) (Ashtekar et al. 2022). The multi-gene phylogenetic analysis indicated that isolates of P. thailandense formed a distinct clade within Penicillium section Citrina, and as a sister clade to P. sanjayi. Moreover, a pairwise nucleotide comparison of BenA, CaM, and rpb 2 data also indicated that P. thailandense differs from P. sanjayi by having 1.56, 1.64, and 1.52 % bp differences (7 / 448, 9 / 550, and 15 / 987 bp), respectively.	en	Khuna, Surapong, Kumla, Jaturong, Thitla, Tanapol, Hongsanan, Sinang, Lumyong, Saisamorn, Suwannarach, Nakarin (2023): Penicillium thailandense (Aspergillaceae, Eurotiales), a new species isolated from soil in northern Thailand.
