REPORT OF THE STATE BOTANIST I906 



33 



Piletis 8-15 lines broad; stem about i inch long, 1.5-2.5 lines 

 thick. 



Gregarious or cespitose in woods of oak and pine. Shore of 

 Hammond pond near Boston, Alass. November. I\Irs E. B. Black- 

 ford. This species is similar in size and color to Hygrophorus 

 q u e 1 e t i i Bres. but that species is described as having the margin 

 of the piieus viscid when young and adorned with white flocci, the 

 center of the piieus covered or spotted with reddish squamules or 

 flocci and at length rimose areolate. the lamellae tinged with citrine 

 yellow,, the stem solid and furfuraceous or squamulose and the 

 habitat is said to be larch woods only. None of these characters is 

 applicable to our plant. It also resembles H. subrufescens 

 Pk. in size and color but it differs from it in its more glabrous piieus 

 with paler margin, its white flesh, stuffed or hollow stem and later 

 time of appearance. This last character is suggestive of the name 

 given to the species. 



Xylaria polymorpha combinans n. var. 



Club subglobose, often compressed and irregular, cespitose at the 

 top of a common subterranean stem or of two stems united at the 

 top; perithecia and spore character as in the species. 



Growing from roots of a dead maple tree. Bridgeport, Ct. 

 November. P. W. Graff. The subterranean stem is about 2.5 

 mches long, the clubs 1-1.5 broad. The clubs appeared as if resting 

 on the ground. The subglobose shape of the club or stroma is char- 

 acteristic of X. polymorpha h y p o x y 1 e a Nits, and the ces- 

 pitose mode of growth, of X. polymorpha spathulata 

 Pers. This combination of characters of two varieties in one is 

 suggestive of the varietal name here given. 



REMARKS AND OBSERVATIONS 

 Agastache scrophulariaefolia (AA^illd.) Kuntze 

 This is a very variable species. A peculiar form occurs near 

 Port Jefferson, ni which the leaves are abruptly acuminate or cus- 

 pidate and the upper ones are entire or nearly so. The flower spikes 

 are more narrow than usual and are sometimes interrupted toward 

 the base. 



Boletus nigrellus Pk. 



A form of this extremely rare species was found in Sand Lake in 

 which the piieus is yellowish or greenish yellow when fresh, and
