5. Agaricon Adans. Fam. 2:10. 1763.—Founded on 
Tournefort’s pi. 330 and Micheli’s pi. 60, the first of which rep¬ 
resents P. igniarius (L) Fr. The genus is, however, not estab¬ 
lished upon a binomial and moreover the name is preoccupied by 
Agaricus L. 
6. Pori a (Brown) Adans. Fam. 2:10. 1763. — Based on 
Mich. PI. 61. f. 2. 1729, a polynomial and as yet undetermined spe¬ 
cies. Plill used Poria for one of the large punk fungi in his Nat. 
Hist. 2:40, 1751 and he also had a genus Porium ( 1 . c. p. 28) 
which seems synonymous with Boletus. In none of these cases 
is the genus properly established. 
7. Polyporus (Mich.) Adans. Fam. 2:10. 1763. — Based 
on P. leptocephalus (Jacq.), which stands first in Micheli’s list of 
species under his new genus Polyporus in Nov. PI. Gen. 129. 1729. 
When Adanson restored the name he referred to five of Micheli’s 
figures representing central-stemmed plants, all of which were 
congeneric, one being P. leptocephalus (Jacq.). The genus was 
thus restored by Adanson in its original sense, but does not hold 
because not founded on a binomial species. 
8. Striglia Adans. Fam. 2:10. 1763.—Founded on Ba- 
tarra’s PI. 38, which represents several common species of Agari¬ 
cus, the first being A. quercinus L. The genus is thus synony¬ 
mous with Agaricus, even if considered properly established with¬ 
out a binomial basis. 
9. Sesia Adans. Fam., 2:10. 1763. — Founded on S. hir- 
sutum (Schaeff.) [L. saepiaria (Fr.)] figured in two positions 
by Vaillant in Bot. Par. pi. 1. fig. 1-2. 1727. The specimens 
were collected on the timbers of a boat at St. Cloud. The draw¬ 
ing is well done and leaves no doubt as to the identity of the 
plant. The lack of a binomial, however, prevents the proper es¬ 
tablishment of the genus. 
10. Serda Adans. Fam. 2:11. 1763. — Founded on Vaill. 
Bot. Par. pi. 1. fig. 3. 1727. This figure is not so clear as the 
first two but it very closely resembles an old resupinate form of 
Sesia hirsutum (Schaeff.) [L. saepiaria (Fr.)]. Add to this 
the fact that the plant was collected at the same time on the same 
host and I think one is justified in regarding Serda as a synonym 
of Sesia, the two being separated by Adanson because one was 
resupinate and the other was not. 
11. Cellularia Bull. Herb. France. 9. pi. 414. 1788.— 
Based on C. cyathiformis Bull., a single species, which is appar¬ 
ently the undeveloped form of some other plant, possibly P. ver¬ 
sicolor (L.) Fr. or Lenzites betulina (L.) Fr. Owing to the un- * 
certainty regarding the identity of this plant it cannot be accepted 
as the type of a genus. 
12. Ceratophora Humb. FI. Friberg. 112-114. 1793.— 
Erected upon a monstrous variety of Boletus annulatus Schaeff 
(Trametes odorata (Wulf.) Fr. called Ceratophora fribergensis
