Indiana Fungi-II. 



J. M. Van Hook. 



The collecting of fleshy fungi during the mouths of July and August 

 was almost a total failure, due to the extreme dry weather. On the other 

 hand, the continued rainfall during September and October was pro- 

 ductive of a great many species common to the fall months. Many of 

 these had not been met with during the four years previous to 11)11. It 

 is interesting to observe during such seasons how the rains will awaken 

 apparently dormant mycelia which produce immense quantities of sporo- 

 phores. Moreo^'er these seem most abundant on dry exposed liillsides, 

 which under ordinary conditions produce but few mushrooms. 



One plant not previously observed was Ar miliaria nardosmia Ell. 

 This species grew in abundance in several places in Brown and Monroe 

 counties in October. It is one of our most attractive mushrooms (Fig. 1). 

 In color and general appearance it reminds one of the soft feathers of 

 our native pheasant. 



Likewise specimens of Lactarius sordidus Plv. were abundant in sit- 

 uations commonly very dry. (Fig. 2.) 



One of the most interesting things ever observed by the writer was 

 a most splendid fairy ring formed by Clavaria formosa Pers. This ring 

 was complete ; about twenty feet in diameter and composed of "bunches" 

 for the most part six or eight inches in height and two to four inches in 

 diameter. 



One species collected the year before and resembling in its manner 

 of growth Institale maxuna, which is occasionally found on the hymenium 

 of the common Fames applanatus, was found on the hymenium of a re- 

 supinate form of Fomes conchatus. Specimens of this were sent to Dr. 

 Peck, who describes it in the New York State Museum Report for 1910 as 

 a new species, Sporotriclium chryseum Pk. The following is his Englisli 

 description : "Hyphte slender, 3-4 microns thick, continuous, long, intri- 

 cate, hyaline, forming a soft, thin, subrosy separable membrane, golden 

 yellow beneath ; spores abundant, minute, globose, 2.5-3 microns in diam- 

 eter."
