C2CC0FD87E195EAF8E273B0B8C35EDF4.taxon	description	Culture characters. This fungal strain exhibits optimal growth on all tested media at 30 ° C, whereas growth is restricted or completely inhibited at 35 ° C. On PDA, at 30 ° C, the colony slowly covers a 60 - mm Petri dish within 10 days, displaying a grayish-white color with a radial growth pattern and fluffy texture. Conidiation initiates after 15 days, producing numerous white conidia that aggregate into irregularly margined patches. On SNA, growth is the slowest among the three media; at 30 ° C, the colony reaches a radius of 50 mm after 10 days, remaining white with a radial pattern and sparse hyphae. Conidiation begins 15 days post-inoculation, forming white, irregularly margined conidial patches composed of aggregated conidia. No odor or pigment diffusion is detected. On MEA, at 30 ° C, the colony rapidly covers the entire 60 - mm dish within 7 days, featuring a well-defined border, radial growth, and creamy-white mycelium with dense, abundant aerial hyphae. No distinct odor or diffusing pigment is observed.	en	Wang, Feihu, Xu, Xiulan, Liu, Feng, Xiang, Shasha, Li, Xinyue, Liu, Yinggao, Yang, Chunlin (2025): Four new species of Trichoderma (Hypocreaceae, Hypocreales) discovered in the staple food bamboo of pandas.

7627F68417F25586818815C3A27B0E1F.taxon	description	Culture characters. Three media were tested for fungal growth: potato dextrose agar (PDA), oatmeal agar (SNA), and malt extract agar (MEA), all incubated at the optimal temperature of 25 ° C. On PDA, the mycelium fully covered a 60 - mm Petri dish within 8 – 10 days, forming a circular colony with a regular margin and velvety to floccose surface hyphae arranged radially. Abundant aerial hyphae extended toward the margin, becoming floccose post-conidiation. By day 12, conidiation initiated around the inoculation plug, forming small white clusters that expanded peripherally while remaining white. No diffusing pigment or distinct odor was detected. On SNA, growth was slower, requiring 20 days to fully colonize the dish (colony diameter: 20 mm after 12 days). The colony remained white and transparent, with sparse mycelium on the agar surface. Central mycelia became hollow, forming a loose, white film-like structure. No pigment or odor was observed, though the inoculation site gradually greened, conidia were absent. On MEA, rapid growth covered the dish within 7 – 9 days, yielding a circular, transparent colony with conspicuous variation in hyphal width (no zonation). Aerial hyphae were sparse initially but thickened at distal / lateral margins over time. By day 11, conidiation initiated on aerial hyphae near the proximal margin, forming fluffy tufts that compacted into 1 – 3 mm pustules with, pustules remained white for 5 – 8 days, then turned brown. No diffusing pigment or odor was detected.	en	Wang, Feihu, Xu, Xiulan, Liu, Feng, Xiang, Shasha, Li, Xinyue, Liu, Yinggao, Yang, Chunlin (2025): Four new species of Trichoderma (Hypocreaceae, Hypocreales) discovered in the staple food bamboo of pandas.
