represented by Hebeloma, Inocyhe, Cortinarins, Tuharia and 

 several Gasteromycetes. 



The genus Inocybe is particularly prevalent on the sand-dunes, 

 especially in the hollows clothed with Salix repens, and the 

 long mycelial threads ramify among the roots of the Salix and 

 grasses in the vicinity. It should be noticed that the under- 

 ground stems and roots of the dwarf willow are densely packed 

 beneath the surface and, as they decay, afford unlimited food 

 for saprophytic fungi. The dominant species are Inocybe 

 rimosa, I. eidheles and /. dulcamara which are plentiful during 

 a long season, and other species not infrequently met with are 

 /. scaber Mull., /. mutica Ft., I. cervicolor, I. asterospora, and 

 /. diiriuscula Rea. Specimens of the last-named were sub- 

 mitted to Mr. Rea for confirmation by our late friend Dr. Ellis. 

 In September and October Armillaria ramentacea occurs in 

 considerable abundance in association with the dwarf willow. 



In similar places Cortinarius [Myxacium) collinitus is also 

 very frequent, and less commonly Cortinarius {Dermocybe) 

 caninus, C. {Telamonia) hinnulius, C. [Tel.) limonius, C. (Tel.) 

 lucorum, C. {Tel.) rigidus and C. (Tel.) injticundus. In late 

 summer Hebeloma mesophaeum var. minor Cke. appears in 

 great troops in the flats between the sandhill ranges, and in 

 fact it is in these moist Sa//A:-covered slacks that fungi are most 

 frequent, and the majority of those already mentioned occur 

 in them. In the spring time, about May, Verpa digitaliformis 

 may be found in damp places among the dwarf willow, and our 

 member Miss Blackwell informs me that she has traced the 

 mycelium to the roots of Luzula and Salix repens. Morcehella 

 esculenta occurs, but rather sporadically. 



Further inland the dunes are better clothed with more mixed 

 vegetation in which Pyrola, Parnassia and Orchids are con- 

 spicuous, and in places large areas covered with the creeping 

 Rubus caesius. Here we find a greater variety of fungi. 

 Uredinales are numerous, especially interesting being Ustilago 

 hypodytes on Elymus arenarius, and the Caeoma stage of Melamp- 

 sora Orchidi-repentis on several kinds of orchid especially 

 Orchis incarnata and Listera ovata ; but in spite of the abundance 

 of Parnassia I have never found Uromyces on its leaves, although 

 at Mr. W. B. Grove's suggestion I have searched frequently 

 for it. The following agarics make their appearance here in 

 addition to those already mentioned: Clitocybe dealbata, C. 

 <^gg^^g<^t(i, C. ericetorum, Hygrophorus conicus and several other 

 common species of this genus, Tricholoma nudum, Lepiota 

 crisfata, Entoloma sericeum, Entoloma nigrocinnamomeum, 

 Clitopolus prunuliis, Bolbitiiis fragilis, B. tener, Galera rubi- 

 ginosa, Hebeloma mesophaeum, H. strophosnm. The "puff-
