74 Mycoloyical bulletin Xo. 10 [ Vol II 



includes 14 species in One Thousand American Fungi, one species illustrated 

 liy a half-tone plate, and three species shown in a colored plate. We have 

 shown, in the Mycological Bulletin, Hi/-j>Jio-}<>'-i)>a siih-hit-cr-l'-ii-um on 

 page 25. and Hij-pho lo'-ma Uic-rif-ma-hun'-dum on page 57. 



Havexel's Phal-loii>. — On page 71 a figure was given o^ Dic-tij-oph'-o ra 

 rn-rc-HfJ'i-i. or in simple language, KaveneFs Phalloid ; but space was want- 

 ing for an account of the specimen's from which the photograph was made 

 and reference to the interesting characters of this fungus. The fresh "eggs" 

 — such as shown in the left figure above — were sent in quantity l)y Supt. 

 M. p]. llard. of Chillicothc, and keeping them moist in Sphagnum, the devel- 

 opment took place with consideral)lc rapidity, as indicated in the successively 

 developed forms in the plate on page 71 The thick riiliui ruptures at the 

 apex with one or two wide clefts and the central column then (dongates 

 rapidly. The cap-shaped or bell-shaped pileus is covered with the spore 

 bearing layer which is called the (jlc'-ha. 



In Kavenel's Phalloid the surface of the pileus is uu'rely granular or 

 minutely wrinkled after the gleba melts away, but in other species there is a 

 conspicuous reticulation of ridges and crests, remotely suggestive of the 

 pitted cap of a Morel. The plant presented in bmgitudinal section shows 

 that the stem is hollow, and this cavity extends ((uite to the apex, the per- 

 foration being conspicuous from above where it is surrounded by a broad 

 light-colored circular lip. The pitted or spongy character of the tissue of the 

 stem can be determined from the figure. It can be seen also that the cap or 

 pileus is attached only near its apex. Beneath the cap is a rcil — character- 

 istic of this genus. 



Botanists include the Phal-loids and their near relatives in the group 

 called PhaJ-Jhi-i'-ae. of M-hich about 50 species have been described. Most of 

 the forms are found in the Trojjics — es})ecially in Australia; about 10 

 species are reported for Xorth Anu'rica. 



The group contains the two orders, Cldtli-id'-cr-dc and I'lial-la'-ec-ac : 

 the latter includes the Phal'-loids or Stink-horns and they are enumerated 

 under 7 different genera. The species most likely to be encountered are 

 members of the genus Dic-tij-oph'-o-ra (as .shown in B^ig. 65, alluded to in the 

 account above) and Ith-ji-pliaV-hts. The unbearably vile-snudling Stink- 

 horn, comuKm in our region, is Ith-y-jilial'-lKs im-pK'-di-ciis. 



The Ivory Hy-groimi'-o-rus. — This species, -which we illustrate on the 

 opposite page, is common in pine woods in Idaho according to the interest- 

 ing account by Professor L. F. Henderson. He says that it occurs in im- 

 mense (|iiantities — tons upon trms could be collected in the wooded hills of 

 Idaho from September to December — and although coated with a slimy cov- 

 ering, cansiiig it ofte;i to slip from the luinds like an eel, when cleaned nicely 

 and cooked into a stew nnikes a delicate dish of oyster flavor — having a 

 decidedly vegetable rather than meat ilavor. The i)lants are from om* to four 

 inches wide and three to six inches high. The entire phint is white and the 

 gills are decurrent. The i)ileiis is rather thick. gemM'ally Hat or convex, 

 though in age it may become lilted upwards ; it is alwiiys incurved along the 

 edge when young. 



Professor Henderson says many other sja-cies of this interesting genus 

 are to be fouiul abundantly in fir woods, or in forests of mingled pine and fir, 

 but he Inis reserved the discussion of these I'or his future Hulletius. It is 

 supposed that all of the species arc edible ; they present various slnides of 

 colors from white, yellowish-white, yellow, yellowish-red. to dull brownish 

 or dirty olive. He says, besides, that theyall iigree in the following ini- 

 jiortant generic characti'rs: 



The gills are rather distant, of a waxy consisti^m-y, broadening towards 

 their attachment to the ca]); ami the central portion of the gill, called the 

 Ira'-nui. is but a continnatiou of the material of the pileus, so that when 

 they are pnlbid off I'rom the cap they eaeh leave a iirojecting line of the trama 

 bcdiind them on the cap. 



This genus is closidy related \i> ('(nilhd-rcl'-his. but in the latter the 

 gills are blunt ami forked.
