Syst. Myc. i. p. 426. Fleshy, with an inferior hymenium spread over teeth resem- bling broken gills.

A genus nearest to Irpext but clearly distinct by reason of the gill- like, irregularly arranged, distinct, non-concatenate teeth, and by the fleshy substance. Fr. Hym. Eur. p. 618. 1. S. confluens Pers. — Entire, shining 'white. Pileus cent. (Yz-\ in.) broad, fleshy, irregular, horizontal, villous. Stem cent, (i in.) and less long, somewhat ex- centric. Gills (tooth - like plates) flexuous, changeable in LXXVI. Sistotrema coiifluens. Natural size. Section twice natural size. Simple, but csespitose and growing into each other. On the ground and sticks. Uncommon. Autumn. At length yellowish or tinged with brown. Tooth-like plates of the hymenium entire or jagged. Grev. Name—confluo, to flow together. Con- fluent. Pers.

GENUS XXXVI.—Irpex (irpex, a harrow). Fr. Elench. p. 142. Hymenium inferior, toothed from the first. Teeth firm, some- what coriaceous, acute, concrete with the pileus, arranged in rows or like network, connected at the base by folds, which are gill-like (in sessile species) or resemble honeycomb (in resu- pinate ones). Sporophores 4-spored. Growing on wood^ some- what sessile or resupinate, approaching Lenzites and Dcedalece. Fr. Hym. Eur. p.
