 314 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



Fructifications 10 cm. high; pileus 7 cm. high, 3-4 cm. in di- 

 ameter, with lobes up to 3 cm. long; stem 3 cm. long. 



On stump of Quercus. California. March. 



I have seen of this species only a dried specimen which was 

 collected by Lieutenant Mc\Miorter at a military training camp 

 and I am not sure that the species may not be transferred eventu- 

 ally to perhaps Paxillus on account of the thin lamellae, which 

 are, however, very narrow and distant. The species is dis- 

 tinguished by its thick, solid, snuff-brown, glabrous fructifica- 

 tions drjdng with fragrant odor, by globose, colored spores, and 

 by occurrence on an oak stump. 



Specimens examined: 

 California: near Base Hospital, Camp Stewart, Palo Alto, F. P. 



McWhorter, iy^e (in Mo. Bot. Card. Herb., 57269). 



Craterellus (?) Zelleri Burt, n. sp. 



Type: in Mo. Bot. Card. Herb. 



Pileus fleshy when growing, thin, tubaeform, drying Prout's 

 brown, with the erect, spreading margin deeply lacerate — in some 

 cases to the stem and rarely splitting the stem on one side nearly 

 to the ground; stem short, perforate, hollow, even, glabrous, 

 Prout's brow^n ; hymenium drjdng chamois to Naples yellow, even 

 or reticulately plicate and with the larger pores subdivided into 

 smaller, shallow pits more completely covering the under surface 

 of the pileus but present also, although less weU-developed, in 

 patches on the upper side; no gloeocystidia ; basidia simple, with 

 6, or perhaps more, sterigmata; spores colored, even, 8-9 X 

 43^-6 n. 



Fructifications up to 6 cm. high; pileus 3-4 cm. broad; stem 2 

 cm. long, 3 mm. thick. 



On the ground in a dense forest. Oregon. March. 



I have included this species in Craterellus because of the 

 similarity of the subhymenial hjT)hae to the longitudinally ar- 

 ranged hyphae of the pileus and my inability to detect any evi- 

 dence of an underlying hymenium. The aspect of the fungus is 

 that of Craterellus cornucopioides. It is my opinion that this 

 species will eventually be demonstrated to be a Merulius para- 

 sitic or saprophytic on the pilei of Craterellus cornucopioides. I 

 know no Merulius to which this species is referable.
