Comparison between stable carbon isotope analysis and conventional approaches applied in studying the development of Cordyceps sinensis.

Stages	Caterpillar-shaped sclerotium formation		Stiff worm	Stroma sprout
Duration for different stages40	Around 2 months	About 3–5 days	3–4 months	Around 2 months
Stable carbon isotope analysis (δ13C values of subsamples*)	H1 to H2: highest value, initial infection	A3 to Ai: slightly declined	H1 to S1: sharply jumped down	S1-Si: continuously decreased
	H2 to T3: slightly declined, inception
	T3 to A3: sharply decreased, incubation
Field observation in morphology	Could not be observed due to no symptom)40	The larva started to behave abnormally, and its skin colour gradually changed31,40.	Relatively long dormant period40,43 (“Winter-worm”)	The stroma started to germinate at the head for more than 2 months and eventually formed the mature stroma31,41,43 (“Summer grass”).
Macroscopic observation in the growth of mycelia	The inside became hollow and the integument became moist. Then, a white hyphal coil firstly developed at the pharynx and gradually extended to the whole body42.		The stiff worm was gradually coated by mycelia31.	1st: The stroma kept growth for one month to reach the length of around 3 cm. Then, its apex swelled and covered with the granulated perithecium.
				2nd: The stroma continued to grow for 20 days to reach the final length of about 4.5 cm.
				3rd: In the coming 10 days, the stroma would underwent the development period of ascospores, including growth, maturation, and eruption31,41.
Microscopic observation in the growth of mycelia	1st: The infectious fungus firstly invaded the host and formed several spheroid hyphal bodies.			The inner of a stroma was made up of interwoven mycelia, and finally multiseptate and elongate fusoid ascospores were produced31.
	2nd: The hyphal bodies multiplied in the host and gradually formed multinucleate hyphal bodies.
	3rd: The multinucleate hyphal bodies further developed into mycelia through the following processes: budding multiplication, conglobation and connection, and hyphal body fusion. The mycelia continued to grow and completely filled the host body cavity15,16,31,41.

^*S1 to Si, H1 to H2, T1 to T3, and A1 to Ai are the subsamples from the stroma, head, thorax, and abdomen according to their positions, respectively. The italic lower case letter i represents the section numbers of the stroma and abdomen, respectively.
