REPORT OF THE 'COMMITTEE ON BOTANY, 



FOR 1877. 



BY A. E. JOHNSON, M. D. 



Mr. PRESIDENT : — Since my last report, one year ago, 

 I have collected and identified one hundred and two species of 

 plants. Of the Fungi, I have collected ninety-five species 

 new to our State, and fourteen species new to science, the 

 descriptions of which I have endeavored to give fully. I 

 have also collected quite a number of Algae, seven of which 

 I have been able to identify with the aid of the elaborate de- 

 scriptions and fine colored plates of Prof. Wood on the "Fresh 

 Water Algas of the United States," published in the "Smith- 

 sonian Contributions to Knowledge, vol. xix." 



The summer of 1877 was noted for extreme heat all 

 over the world, and in our State, as one of extreme drought, 

 there having been scarcely any rain during the whole of July and 

 August. These conditions are very unfavorable to the produc- 

 tion of fungi. Agarics of every genus were very scarce, not 

 one was to be seen where thousands existed in previous sea- 

 sons. Scarcely a boletus has been observed this season; only 

 one or two hydna; a very few polyp >ot -i; scarcely a clavaria 

 or tremella; not a phalloidei, and but a very few trichogastres 

 towards the close of the season; and so with nearly all other 

 orders of fungi, Drought and extreme heat seem to effect 

 the production of fungi more than almost any other plants. 



55g. Agaricus (Tricholoma) rutilans. Schceff. 



"Red-haired Tricholoma." 

 Our plant is not as large as the book description. Not 

 necessarily on pine stumps. On decayed wood. Oct.
