Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1877 edition. Excerpt: ...at first covered by the hyaline membranous epidermis, at length exposed, effused, nearly or quite occupying the whole lower surface of the leaf, ferruginous-brown; spores ovate or oblong-ovate, umbonate at the apex, .001-0018 inch long; pedicel hyaline, short. Living leaves of Snphora tericea, Pursh. Mr. Brandegee remarks concerning this fungus that it is very common at Canon City, about one-half the Sophora plants being affected by it. The plants attacked by it become more erect in habit and do not blossom. The sori sometimes occur sparingly on the upper surface of the leaf also. The specific name is suggested by the hyaline membrane that at first covers them. PuccrtiiA Nigkescens, Pk--Spots none; sori rather prominent, caulinc, oblong, blackish-brown or black; spores smooth, elliptical or oblong, obtuse or bluntly pointed, slightly constricted at the septum, .0015-.001S inch long, .C008-.001 broad; pedicel colorless, two to four times as long as the spore. Steins and branches of Salvia laneeolata, Willd. No leaves of the host plant accompanied the specimens sent, so that I am not able to say whether the fungus ever attacks the leaves or not. The two following species have been received from the sources given at the end of the descriptions: Diatrypeli, a Fhostii. Pk.--Stroma verruciform, rather prominent, convex or hemispherical, scarcely one Hue broad, sometimes confluent, partly covered by the closely adhering fragments of the ruptured epidermis, black externally, greenish within, forming a white spot 011 the wood beneath; perithecia sub-globose, generally ten to fifteen: ostiola obscure; asei sub-cylindrical, scarcely pedicellate, polysporous; spores yellowish in the mass, cylindrical, curved, .00025-.00015 inch long.
