In the ground. 



The type specimens of P. geaster, B. & Br., are somewhat 

 smaller in size than specimens of P. sepulta, Fr., specimens 

 of which, named and communicated by Fries, are in Herb. 

 Berk., but in other respects the two are identical. 



Sepultaria arenicola. Mass. 



Ascophore sessile, subterranean, subglobose then ex-

 of flexuous, interwoven, septate, brown hairs 4-5 ft thick ; 

 excipulum parenchymatous, cells irregularly polygonal, 

 1530 p. diameter, passing into a closely packed row of 

 parallel, slightly clavate, elongated, septate cells at the 

 margin, olive-brown; disc pale tan-colour or brownish, 

 sometimes with a tinge of pink; asci cylindrical, apex 

 rounded, base narrowed into a pedicel, 8-spored ; spores 

 obliquely uniseriate, smooth, hyaline, continuous, broadly
