crust: stratum of tubules occupying about a third of the pileus, fer- 

 ruginous within, their mouths very small and covered but not closed 

 with a white powder. Spores ferruginous, elliptic-ovoid, .008-^01 

 mm. long by .006-007 mm. broad. 



Pileus projecting 2-4 in. with a breadth of 3-6 in. and a 

 thickness at the base of£-H in. gradually thinning out all round to 

 the edge. This species is properly always annual: there are indeed 

 stratified specimens of two or three years growth but in all cast s 

 a new stratum of hymenophore is formed for each annual layer of 

 tubules, leaving the preceding growths to crumble and decay. 



Growing always about the base of old stumps in an ascending 

 position; 1 have never found a spaeimen upon a Log. 1 have m ft 

 with the species from Dayton, 0., down the Miami Valley to Cin- 

 cinnati and into Kentucky beyond Lexington. 



This is a curious member of the group of Fomentarii of Fries. 

 It has passed heretofore for 1\ applanatus, Pers.,but the true applan- 

 afits grows here abundantly upon stumps and logs and Mr. James, 

 Mr. Meyncke and myself readily distinguish one from the other 

 upon sight. It will be seen that it has affinities also with P. lucidus, 

 Leys. — A. P. Morgan. 



Lactlica Scariola, L. — This plant, possessing the habit of the 

 Compass Plant in placing its ve'tical leaves so as to point to the 

 poles, at the time of the publication of Gray's Manual, last edition, 

 was known only at Cambridge, Mass. In a short time it has reached 

 the Mississippi. It is quite abundant at Dayton,Ohio. At Put-in-Bay, 

 Lake Erie it has already become a pest. It is beginning to make 

 its appearance about Detroit, Mich. A few specimens (3-5) were 

 observed by myself at Lincoln in Central Illinois. The above sta- 

 tions I found myself. It is in the list of H. Eggert of St. Louis, 

 Mo. Mr. Bebb has found it at Rockford, ill. The latter city is so 

 close to Wisconsin that the plant probably grows there or soon will 

 reach that state. A friend, not a botanist, but a good observer, 

 claims to have seen the plant near Richmond, Indiana. The geo- 

 graphical distribution of Lactuca Scariola, therefore, west of the 

 Alleghanies, would be Ohio to Missouri ami northward. — Aug. F.

The Gazette for 1888. — The attention of our readers is 

 called to the fact that the time for the renewal of subscriptions has 

 come. Every year has brought a large increase to our subscrip- 

 tion list and we can assure our patrons that Volume VIII will 

 contain much to interest and instruct. And again we would re- 

 peat^ our more modest and retiring botanists what we have said so 

 often, that while giving space to somewhat formal papers it is by 

 no means to the exclusion of notes and scraps of information given 

 in the most informal way.
