20 Journal of the Mitchell Society [June 



pinkish tint, sometimes marked with darker blotches below, nearly 

 smooth or with a thin scurfy tomentum especially below. Flesh 

 solid, colored like that of the cap, but much firmer. 



Spores pure white, warted, sperical to short elliptic, 4.6-6.4 x 6.4- 

 9.2^1. 



In spite of some peculiarities, this plant seems too close to L. silicio- 

 ides Fr. to be separated, and I shall consider it a short-stemmed form 

 of that species. In shape, texture of cap, and very short stem it re- 

 sembles L. atroviridis. Distinguishing qualities are : absence of latex 

 (or very scant) ; very short stem ; surface of dense compacted fibers 

 which are viscid when wet ; inrolled margin covered when young with 

 a roll of loose and not very long fibers which soon collapse; absence 

 of zones, and yellowish orange color. 



This is the first record of this European plant in the Southern 

 States, and it has been found only a few times in the North, Dis- 

 tinctly a boreal species, occurring in cold weather in fall and spring, 

 and always near pines on uplands. 



972. Many plants in all stages, growing among pines in hillside pasture on 

 west side of Glenn Burnie Farm, November 11. 1913. Two photos. 

 These plants were found at the same time and place with a large 

 number of plants of Boletus brevipes, and these two are remarkably 

 alike in size, shape, length of stem, and place and time of growth. 

 There had been hard freezing the preceding two nights and many of 

 the plants were frozen when found. Microscopic examination of the 

 flesh of the cap shows very loosely woven fibers with open places 

 between them and almost no vesicular cells, latex quite absent at all 

 stages in this lot, none being visible even with a lens in young 

 plants just collected.

3015. In sedge among pines near Cobb's Terrace, April 21, 1918. No visible 

 milk, spores 5 x 6-7u,. These plants were typical and showed a very 

 little milk, which was quite peppery and white and unchanging. 

 The milk was so scarce as not to be noticed unless carefully looked 

 for. Spores white, subspherical to elliptic, warted, one large oil 

 drop, 4.2-5.1 x 5.1-7.6„. In these plants the fibrous nature of the cap 

 was not noticeable except near the margin. The surface elsewhere 

 was shiny and nearly smooth from the collapsed and fused, viscidi 

 fibers.
