The paper deals with various tuberiform fungous bodies, most of which have long been 
known. On pages 02-79 is given a full description of Pachyma cocos, Indian bread, or tucka- 
hoe, prefaced by a summary of our previous knowledge on the subject. The author describes 
the anatomy of the tuberiform bodies, recognizing three component parts, liyplue, smooth, 
refractive bodies, and striated lumps, also highly refractive. All of these are considered to 
be of fungous nature and the author shows that the hyplne are changed into the refractive 
bodies, and that often the two can be seen still in actual connection and the intermediate 
stages of the change traced. Intermediate stages can also be observed between the refrac¬ 
tive bodies and the striated lumps. Then the author gives a description of the connection of 
the Pachyma with the roots of trees in two specimens at bis disposal. In botli cases the 
wood was of a dicotyledonous plant, and not of a conifer, which is opposed to a prevailing 
idea as to their mode of occurrence. The hyphae were found to enter the wood cells, swell 
up to refractive bodies and finally to dissolve the wood. On pages 79-97 the sclerotium 
of Polyporus sacer Fr. is fully described and illustrated with plates. The sclerotium is 
composed of delicate liyphae, rounded or oval refractive bodies, much like starch grains in 
appearance, and smaller swollen thick-walled cells rich in protoplasmic contents. The oval 
bodies show concentric stratification when treated with KHO or other solvents. They are 
not connected with the hyphae, though very rarely one could be seen that bore a filamentous 
prolongation. The author concludes, however, that the oval bodies arise from the hyphae, as 
do the irregular refractive bodies of Pachyma. Considers Polyporus scleropodius Lev. as 
very probably the same as Polyporus sacer Fr. On pages 97-102 short accounts are given of 
Tuber-regium, producing Lentinus tuber-regium Fr. and a number of other Lcntinus- produc¬ 
ing sclerotia; of Mylittia lapidescens Horan, pi'oducing Agaricus (Omphalia) lapidescens 
(Horaninow) I’. Conn. and J. Schroeter; of Sclerotium stipitaium Berkeley, which the author 
considers as being a fructification of a fungus and not a sclerotium; ana finally a notice of 
Pietra fungaja of south Italy, which produces Polyporus tuberaster Jacq. (W. T. S.)
