Calvatia caelata (Bull.) Morg. 



Plates 40 and 112 



Plant large to very large, sterile base ample, either long and cylindrical or shorter 

 and tapering to the pointed base; cortex a flocculent layer which is thicker above and 

 there usually areolated into more or less prominent warts, thinner downward, but with a 

 tendency throughout to form more or less stellate, flattish areas; color whitish, then 

 pallid yellowish to brownish. Inner peridium thin, breaking up into fragments at 

 the top, then downward, exposing the bright olivaceous gold to brownish olivaceous 

 gleba, which is very fragile and powdery. Sterile base persistent, up to 9.5 cm. thick 

 and 10 cm. high, furrowed below and pinched to a point; the chambers of the subgleba 

 distinct, empty and moderately large, extending up the sides for several centimeters 

 as a tapering margin to the cup. 



Spores (of the plant from Pawling, New York) spherical, smooth, with a short 

 mucro and distinct oil drop, 3.8-4.5ix. Capillitium threads up to 17/* thick, usually 

 7— 11/i, somewhat branched, easily breaking up at maturity; walls with narrow (about 

 lfi wide), linear, sinuous pits. 



This is a northern and middle western species and so far as we know has not been 

 collected in the southeastern states. Specimens we have seen are from New York and 

 Canada. Curtis reports Lye. caelatum from this state (Cat'l., p. 110), but there is no 

 reason to think that his plant was correctly determined. Calvatia caelata is not rep- 

 resented in his herbarium, but C. craniformis, which he does not report, is found there 

 under the name of L. delicatum B. & C. The species is well marked and very easily 

 recognized by the fibrous or flocculent covering, separated into warts or stellate areas, 

 and by the very characteristic thick capillitium with its conspicuous, linear pits. For 

 treatment of this species see Morgan, Journ. Cin. Soc. Nat. Hist. 12: 169; also Lloyd, 

 Myc. Notes, p. 166 and Lycoperd. Austr., p. 35. Lloyd's magnified figure of the 

 cortex is good. 



The plant is most like C. craniformis in size, shape, and color of gleba, and in the 

 northern states it seems largely to take the place of that species; in the south C. crani- 

 formis is very common, while in the north it is certainly rare. 



Cunningham gives the following list of synonyms for this species: L. Fontanesii 

 Dur. et Mont.; L.favosum Bon.; L. Sinclair ii Berk.; C. favosa (Bon.) Lloyd. (Trans. 

 N. Z. Inst. 57: 190. 1926.)
