‖ Puccinia Bot.
(pʌkˈsɪnɪə)
[Named after T. Puccini, an Italian anatomist.]
A large genus of minute parasitic fungi, N.O. Uredineæ, the species of which are heterœcious. The best-known species, P. graminis, grows as an æcidium on the leaves of the barberry, and its spores produce the Uredo or rust on wheat, rye, oats, and grass.
| 1861 Miss Pratt Flower. Pl. II. 210 A small fungus, the Bramble Puccinia. 1875 Bennett & Dyer Sachs' Bot. 247 The second form of fruit [produced upon the leaves of Berberis] was at one time considered a distinct genus of Fungi, and described under the name of æcidium; but this term is now only used to designate a particular form of fruit in the cycle of development of Puccinia. |
Hence ˈpuccinoid a., allied in form to Puccinia.
| 1874 Cooke Fungi 201 The æcidium which from the same disc produces the puccinoid resting spores. |
