كمء

كَمْءٌ ذ A well-known vegetable, (K,) [the truffle, ] which comes forth from the earth like the فُطْر: or what is called شَحْمُ الأَرْضِ [the fat of the earth ]; and the Arabs also call it جُدَرِىُّ الأَرْضِ [the small-pox of the earth ]: it is also said that the name of كَمْأَةٌ is given to those [ truffles ] that incline to dust-colour and black; and جبأة (q. v.) to those that incline to red: كُحْل and تُوتِيَا are compounded with the juice of this vegetable [to apply to the eye]: Th also mentions كَمَاةٌ [as used for كَمْأَةٌ]. (TA.) The dual of كَمْءٌ is كَمْاآنِ; (S;) the pl. (of pauc., S) أَكْمُؤٌ; (S, K;) and [pl. of mult.] كَمْأَةٌ: (K:) this last is not a pl. of كمء, but a quasi-pl. n.: (Sb, K:) [or كَمْأَةٌ is rather a coll. gen. n. of which the n. un. is without the ة, contr. to analogy: (see جَبْءٌ:)] in speaking of many, you say كَمْأَةٌ, contr. to analogy: (S:) or كَمْأَةٌ is the sing., and كَمْءٌ pl.: or [accord. to some,] كَمْأَةٌ is both sing. and pl.: (K:) AHn mentions كَمْأَةٌ as sing., and كَمْأَتَانِ as dual, and كَمْاآتٌ as pl.: but the right opinion is that of Sb. (TA.) [كَمْأَةٌ also signifies Any kind of fungus, such as the mushroom, and toadstool. See فُطْرٌ.]
