DUBININ NATURAWSTS' FIEI<D ClyUB. 



OCT^OBER 8th. The closing excursion of the season to Glendhu and 

 Tibradden was attended hy twenty-nine members, who drove from 

 Terenure to the wood at Glendhu. Here the party separated. Rev. 

 M. H. Close and Prof. Cole led those interested in geology, first to a 

 gravel-pit showing a good section of the Middle Glacial Drift, with nume- 

 rous limestone pebbles, though a mile on the granite outcrop, and then 

 to the summit of Tibradden. From here the general structure of the 

 country was seen and explained, and the position of the high-level shell- 

 gravels pointed out. Some of the party came down to Glendhu again, 

 but the more adventurous proceeded along the ridge to Two Rock and 

 Three Rock Mountains, the jointed and weathered granite crags on the 

 latter receiving attention, and finally descended to Dundrum. 



In Glendhu the collectors of plants and insects did some good work. 

 Among the insects, the handsome dipteron Bibio pomonce, Fab., was a 

 noteworthy capture. With other, commoner spiders, Drapetisca socialis, 

 Sund., occurred in abundance; this species was first taken in Ireland at 

 the September excursion of the club in 1890. Mr. D. McArdle collected 

 liverworts, and secured the following species: — Friillania dilatata, Linn.; 

 Radula complanata, Linn. ; Lepidozia reptans, Linn. ; Cephalozia bictcspidata, 

 Linn.; C. lammersiana, Huben.; Lophocolea bidentata, Linn.; Kantia tricho- 

 manes, Dicks; Sacrogyna vitiadosa, Mich,; Scapania nemorosa. Dumort; Diplo- 

 phylliun albicans, Linn. ; Plagiochila asplenioides, Linn. ; Jiingennannia ventricosa, 

 Dicks; and many curious forms of Nardia emarginata, Bhrb. 



The October excursion is generally regarded as a "fungus foray." The 

 President, Dr. McWeeney, unfortunately, was the only mycologist present, 

 but the number of species found by him was very large, and Glendhu 

 Wood vindicated on this occasion its reputation as a good collecting- 

 ground for the larger fungi. The moss- covered soil swarmed with agarics, 

 but only a relatively small proportion is included in the following list on 

 account of the dif&culty of certainly identifying the specimens. At least 

 half-a-dozen small species of Cortinarius [Derniocybe], and C. {Hygrocybe) are 

 omitted for this reason. The following species were identified: — Agaricus 

 {Clitocybe) nebulae is, Batsch; A. {Amanita) nmscarius; A. {Tricholoma) terreus, 

 Schaefif; A. {Mycena) galopns, Pers. ; A. {Lepiota) granulosus Scop, var. 

 close to broad-iuoodics ; A. {Galera) nvmophilus Lasch {on Pellia)', A. {Fholiotd) 

 squarrostis; A. (^Hypholonid) sublateritius, Schaeff; A. {Stropharia) cBruginosus, 

 Curt. ; A. {Stropharia) se?niglobatus; Cortinarius {Dcrmocybe) miltinus, Fr. ; C. 

 i^Hygrocybe) near nraceus; Paxillus involutus, Fr. ; Russula nigricans, Fr. ; R. 

 rubra, Fr. ; R. emetica, Fr. ; R. ochroleuca, Fr. ; Laciarius rufus, Fr. ; Boletus edulis 

 (large specimens seven and a-half inches across pilens, and seven inches 

 round thickest part of stipes); Clavaria inccqualis ; "Flo. Dan."; Calocera 

 viscosa, Fr. ; Hydnum repandum, Linn; Helvella lacunosa, Afz. ; Chlorosplenium 

 ceruginosum, "Flo. Dan.," with fine cups; Helotiu?)i conigenum, Pers., and 

 Peziza vesiculosa, found by Mr. McArdle, and identified by Mr. Phillips, of 

 Shrewsbury, comprised the Discomycetes. The imperfect stage of Hypo- 

 inyces sp. known as Sepedonium chrysospcrniuiii, was found plentifully on 

 dead Boleti. The most remarkable finds, however, were amongst the 

 lower orders of Fungi. A brown hyphomycete with coiled spores close 

 to Helicoma, but not identical with //. viitlleri, Ca., the only species given as 

 British b}^ Cooke; and a still more curious species, Ptychogaster albus, Ca.., 

 for some time proved quite a puzzle. 



The only Uredinese found were a Pucciiiia on a plant of Viola canina, 

 another on the Spear- thistle, and Phragmidium violaceuvi with uredo-spores, 

 and mature and immature telento-spores on one and the same bramble 

 leaf. 



The commonest agaric was a yellow Russula close to if not identical 

 with R. satdonia and very acrid. It occurred in troops throughout the 

 wood. The number of species in the above list might readily have been 

 trebled had a division of labour been practicable in the work of collection 

 and identification.
