Table 2

Spawn running (mycelia development) and primordial (pinhead) formation days of the four Pleurotus species on different substrates.

Pleurotus species	Substrate	Spawn running (days)	Pinhead formation (days)
P. citrinopileatus	CHs	18 ± 1^a	23 ± 1^e
	CP	17 ± 1^a	25 ± 1^a
P. eryngii	CHs	20 ± 1^b	26 ± 1^a
	CP	19 ± 1^b	28 ± 1^b
P. ostreatus	CHs	15 ± 1^c	20 ± 1^g
	CP	14 ± 1^c	22 ± 1^h
P. sapidus	CHs	17 ± 1^a	22 ± 1^h
	CP	16 ± 1^c	23 ± 1^h

All values are means of triplicates ± SD. Levels not connected by the same letter under the same column are significantly different (). CHs = coffee husks, CP = coffee parchment, SD = standard deviation.
