By October first, many of the branches had produced large numbers of the fruit-bodies with mature spores (Fig. 3, r.). These resembled in nearly every detail the specimens of Pleon- ectria berolinensis, Ellis and Ever- hart's North American Fungi, No. 470. The perithecia are minute, smooth; spherical or p e a r- shaped bodies, and are usually borne in clus- ters closely crowded together. The color is brick-red or reddish- brown, bright when the plants are fresh, but duller when dry. Each cluster is usually seated upon a more or less distinct stroma, but seldom, if ever, is this a cushion of Tu' berciilaria. Most of the specimens examined seem to be nearly sessile upon the wood, but an evident stroma is shown in Fig. i beneath the bark, but as they grow older and larger, they -,- break through and appear on the surface, bordered by the ruptured edge of the epidermis. Occasionally, several clusters are joined side by side, forming a ring extending nearly around the stem. In some instances, when the bark had been torn away, the perithecia are not clustered, but entirely distinct and superficial on the wood. In such cases there is no evidence of an underlying stroma, cer- tainly none of Tubercularia. When fresh the perithecia are swollen out and nearly spherical; but when old and dry, the apical Longitudinal section of a cluster of peritJiecia of Pleonectria, The clusters originate.
