OBSERVATIONS ON SOME SPECSES OF NEAPOLITAN FUNGI. 113 
live on the locust tree ( Ceratonia Siliqua), we did not find sufficient 
characters to make it a distinct species ; but, observing the ten- 
dency in the examined samples towards the simple form, and 
wanting to distinguish the latter, we prefer considering it as the 
simple and not caespitose form of Polyporus sulphureus. We 
have continued during the present year our researches, and have 
found on the locust tree itself examples of Polypori no more 
simple, but caespitose, and which, in form, spores, and colour of 
flesh, resembled other samples found on the Almond ( Amyg- 
dalus communis') and other trees. The latter samples belong, 
without doubt, to the species P. sulphureus, Fr. It follows, from 
what has been said, that the only differential character of the sim- 
plicity of form of the locust tree polyporus being yet doubtful, we 
must conclude that the P. Ceratonioe, Risso, corresponds essentially 
with P. sulphureus, Fr., which is so polymorphous. But, more- 
over, to the samples collected on the locust tree corresponds the 
other characters given by Insenga to his P. Todari, for the afore- 
said locust tree polyporus presents “ il margine acutissimo, spor- 
gente, ondeggiante, e serpeggiante,” as Insenga himself wrote to 
me (Fung. Nap., p. 107), “ rivoltato un poco indietro nella sua 
estremita, di color miniato, molto carico e formante una 
zona colorata e distinta per tutta la circonferenza del fungo ” 
(Fung. Sic., I., p. 38.) As a last proof, we may add that the 
fungus of which Clusio speaks, 'exactly interpreted by Fries as P. 
sulphureus, is coloured in the following manner : — “ Colores fla- 
vus et ruber simul mixti * * extimae orae satura rubedine 
nitent” (Cius. Rar., pi. Hist., p. 278.) Therefore, if the same 
diagnostic characters are common to the three species of Polypori : 
P. sulphureus , Fr., P. ceratonioe, Risso, P. Todari , Ins., we are 
obliged to conclude that the said three species must be reduced to 
one, viz., to the old species, to the P. sulphureus, Fr. ; and the 
P. ceratonioe, Risso, and the P. Todari, Ins., ought to be considered 
amongst the many synonymous names of the P. sulphureus , Fr. 1 
Conclusion. 
We propose that the following species, of which we give the 
abbreviated diagnostic phrase, be considered in the list of the 
Hymenomycetes Europaei : — 
lo. A. caeruleo-viridis. — Brig. jun. — Neap., p. 9,t. 3, f. 1-2 (sect. 
Armillaria). 
Pileo carnoso, e campanulato expanso, laevi, viscoso, glauco; 
lamellis confertis, amoene lacteis ; stipite ab annulo ad basim 
squamulis obducto, dilute glauco. 
2°. A. Neapolitanus. Pers. — Myc. Eur., iii., p. 73; A. coffece, 
Brig. Nap. t. 23-26 (sect. Clitocybe). 
Albus, caespitosus, raro gregarius ; pileo carnoso e plano depresso 
infundibuliformi, limbo tumidulo et incurvo ; lamellis albis, inaequa- 
libus, decurrentibus ; stipite subicentralis, solido. — Provenit ex 
Coffeae potus faece.
