Indiana Fungi-II, 



J. M. Van Hook. 



The collecting of fleshy fungi during the months of July antl 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 mouths. Many of 

 these lind not been met with during the four years previous to 1911. It 

 i.s interesting to observe during such seasons how the rains will awalven 

 apparently dormant myeelia which produce immense quantities of sporo- 

 phores. Moreover these seem most abundant on dry exposed hillsides, 

 which under ordinary conditions produce but few mushrooms. 



One plant not previously observed was Armillaria nardosmia Ell. 

 This species grew in abundance in sevei'al 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 sonlidiis Pk. were abundant in sit- 

 uations commonly very dry. (Fig. 2.) 



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

 a most splendid fairy ring formed by Clararia fonnosa Pers. This ring 

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

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

 diameter. 



One species collected the year before and resembling in its manner 

 of growth Institalc maxima, which is occasionally found on the hymenium 

 of the common Fomes applanatus, was found on the hymeiaium 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, 8i)orotriclium chryscum Pk. Tlie following is his English 

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

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

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

 eter."
