with a downy sky-blue pileus; A. campanella 

 Batsch., syn. A. caulicinalis Sow., t. 163., and our 

 fig. 2019.; A. lepideus Fr., syn. A. squamosus 

 Schceff., t. 29., and our^g. 2020. Monstrous forms 

 of this fungus occur in dark situations, with or 

 without a pileus, exactly analogous to certain 

 states of Polyporus squamosus. Such are figured 

 by Schaeffer at t. 248. and 249., and by Sowerby at t. 382., under the name of 

 A. tubaeformis. A. porrigens Pers. Syn., p. 480., found by Herr Klotzsch near 

 Inverary; A. flavidus Schceff., t. 35., and our^. 202 1 . Merulius pulverulentus 

 Fr. EL, v. i. p. 60., syn. Auricularia pulverulenta Soiu.; one of the 

 species known under the name of dry rot; first found at Ash Hill, 

 in Norfolk, on fir beams in a wall. Dasdalea sepiaria Wulf., syn. 

 ^garicus 6oletiformis Sow., t. 418.; found upon unsquared deals in 

 a Thames dock. Daedalea #bietina Fr. Syst. Myc, i. p. 334., Agk- 

 ricus abietinus Bull., t. 442. ; a nearly allied species, found in a 

 similar locality at Glasgow. Possibly both these have been imported 

 into our dockyards. Polyporus caj v sius Fr. Syst. Myc, v. i. p. 360., 

 syn. boletus albidus Sow.,t. 226.; remarkable for turning blue when 2021 

 bruised ; a property which exists in an eminent degree in several Poleti, and 

 appears to arise from a chemical change taking place in the juice of the plant 

 when exposed to air. Pol. irregularis Klotzsch ; syn. Bo\. irregularis Sow., t. 

 423., Pol. amorphus Fr. Syst., i. p. 364., Pol. abietinus Pers. Syn., p. 541., 

 Grev. Sc. Cr. Fl., t. 226.; a very beautiful species, elegantly tinged with 

 violet. Pol. joinicola Fr. Syst. Myc, v. i. p. 372. ; found on pine trunks in 

 Scotland, by Mr. Arnott. Pol. undatus Pers. Myc. Eur., v. ii. p. 90. t. 16 . 

 f. 3; Pol. incarnatus Fr. Syst. Myc, v. i. p. 379.; Pol. armeniacus Berk. 

 Eng. Fl., v. v. p. 147., a beautiful buff and white species, found 

 amongst the treasures of the collection of Capt. Carmichael. 

 I'rpex pendulus Fr. EL, v. i. p. 143. ; syn. i7ydnum pendulum 

 Alb. et Schiv., t. 6. f. 7. ; Thelephora sanguinolenta Alb. et 

 Schw., p. 274., Grev., t. 225., and our fig. 2022. ; Thel. amorpha 

 Fr. EL, v. i. p. 183. Thel. lactescens Berk. Eng. FL, p. 167., 

 and Brit. Fungi, No. 21.; remarkable for distilling drops of milk when 

 wounded, which, in taste and smell, resembles that of Ag. quietus. This 

 species occurs also on the elm. Thel. gigantea Pers. Myc. Eur., v. i. p. 150.; 

 Thel. iivida Fr. Syst. Myc, v. i. p. 447. Thel. puteana Schum., Fr. Syst. 

 Myc, v. i. p, 448. ; a peculiarly hygrometric fungus, which occurs in houses. 

 When placed, after being gummed on paper and preserved in the herbarium 

 for several weeks, in the cupboard where the fungus was first found, and 

 where it had been entirely destroyed by a solution of corrosive sublimate ; 

 though the woodwork, which, in consequence, in an unusually damp 

 season, had before been constantly dripping, was quite dry; it, 

 in 12 hours, recovered its original fleshy appearance, and was studded 

 with drops of coffee-coloured moisture. (Berk, in Mag. of Bot. 

 and ZooL, v. i. p. 44.) Calocera viscosa Fr. Syst. Myc, v. i. 

 p. 486.; syn. Clavaria viscosa Pers. Comm.,t. 1. f. 1. Peziza caly- 

 cina Schum., syn. P. pulchella Grev. Fl. Ed., p. 421. ; extremely com- 

 mon on fallen branches of the larch. Pez. buccina Pers. Syn., p. 

 659.; Pez. sanguinea Pers. Syn., p. 657.; Pez. xanthostigma Fr. 

 Obs., i. p. 166.; Pez. flexella Fr. Syst. Myc, v. ii. p. 152.; Ditiola 

 radicata Fi ♦ Syst. Myc, v. ii. p. 170., and our fig. 2023. Helotium 

 radicatum Alb. et Schw., t. 8. f. 6. ; a very beautiful, but destructive, fungus, 

 growing on boards of Pinus sylvestris. The mucedinous roots insinuate 

 themselves between the fibres of the wood, and, creeping far and wide, sepa- 

 rate, and at length render the substance soft and rotten, by exhausting its 

 nutritive particles. Besides which, from the erumpent mode of growth of this 

 fungus, the wood is rendered pervious to the rain, and, in a few years, 

 becomes brittle and perishes. The roots are perennial, and put forth fresh
