ST. ALBANS AND ITS NEIGHBOURHOOD. 
were the Grorhambury estate, St. Albans (Verulam Woods, the 
Hollows, and Grorhambury Park), in 1884 and 1896, and Bricket 
Wood in 1889 and 1891. The collections made at the first 
of these forays were examined and named by Dr. M. C. Cooke 
and Mr. Worthington Gr. Smith, and those at the other three 
by Mr. George Mas see. 
There are about 370 items in the lists, which include 
duplications of certain species, either gathered on more than 
one occasion or observed in different localities. Deducting 
these nearly 250 species are recorded. 
Of the Hymenomycetes the comprehensive genus Agctricus 
furnished about 120 species from Bricket Wood and 50 from 
Grorhambury, of which 28 are different from those recorded for 
Bricket Wood. Of other genera such as Coprinus, Cortinarius, 
Lactarius, and Polyporus, upwards of 60 species are enumerated. 
Of the genus Lactarius, 14 species were observed in Bricket 
Wood and 3 at Grorhambury, 2 of which are common to both 
localities. The edible L. deliciosus is absent from both lists. 
One of the most noteworthy records is that of Lenzites betulinus 
for Bricket Wood, this having been previously observed in only 
two stations in England. The genus Stereum is represented 
by only one record, that of S. hirsutum for Grorhambury, but 
the writer has observed it also in Bricket Wood. It is common 
on decayed tree-stumps and may be found at all seasons of 
the year. One may sometimes see on it the plasmodium of 
Badhamia utricularis, either feeding on the microbes distributed 
on the surface of the fungus, or absorbing some of the nitrogenous 
elements of the host plant. The passage of the plasmodium 
leaves the Stereum evidently deteriorated. 
The GJ-astromycetes are represented by 3 species of Ly coper don, 
of which L. gemmatum is the most frequent; and by 2 of 
Schlero derma. 
Of the Ascomycetes the curious candle-snuff fungus, Xylaria 
hypoxylon, is recorded for both localities and is certainly one 
of the commonest of the fungi which grow on decayed stumps; 
several other genera are also represented. 
Mr. Salisbury reports that the Uredinese are well repre¬ 
sented, many species being almost ubiquitous ; such are 
Puccinia anemones, P. malvacearum, Trichobasis suaveolens, 
Uromycesficarias, JEcidium ranunculacearum,Lecythea capr dearum, 
L. euphorbias, and Phragmidium bulbosum\ and that amongst the 
less common forms are Puccinia adoxae, P. centaureae, JEcidium 
violas, A. guadrifidum, JJromyces concentrica, and TJredo bifrons. 
It is evident from the preceding remarks, which give some of 
the results obtained during a very small number of searches, 
that a systematic and persistent series of observations would 
add considerably to the number of species which may be found 
in the woods which furnished these records. The writer has 
observed at Harpenden on several occasions the “ stink-horn,” 
Phallus impudicus, which, as the common name suggests, may
