Sorry, did not see this comment until after I submitted my other comment. Are there other characteristics that distinguish C. fuscata from C. carnea? I did find other plants that were more pink nearby. Would you like me to upload one of those images as well?
In general C. fuscata tends to be paler and whiter in colour whereas C. carnea is often brighter. Unfortunately they do have a bit of overlap with their colouring, so it isn't always that useful for ID. I have written some key ID dotpoints below. C. fuscata is typically: - single flowered - flowers early spring - has a delicate, reddish-brown stem - paler colouration C. carnea typically: - 2 or more flowers - flowers mid to late spring - robust, green stem - vivid colours Of course both species can exhibit the characteristics of the other, but they are generally as above.
