section only of Merulius. Gray uses Merulius for a part of the 
genus Cantharellus and Link had proposed the name Xylophagus 
for the section Serpula of Persoon as early as 1809. 
28. Grifola S. F. Gray, Nat. Arr. Brit. PI. 11643. 1821.— 
Based on G. frondosa (Dicks.) and five other species, only one of 
which is congeneric with the type. 
29. Coltrica S. F. Gray, Nat. Arr. Brit. PI. 1:644. 1821. 
Based on C. perennis (L.) and two other species which belong in 
a different genus. 
30. Albatrellus S. F. Gray, Nat. Arr. Brit, PI. 11645. 
1821.— Founded on A. ovinus (Schseff.) and one other species. 
Gray's citation of Micheli as the author of this and several other 
generic names used by him is not in accord with modern usage, 
since Micheli did not use these names for properly constituted 
genera. Synonymous with Scutiger Paul, established in 1793. 
31. Strilia S. F. Gray, Nat. Arr. Brit. PI. 11645. 1821. 
— Based on S. cinnamomea (Jacq.), a single species, which if 
not identical with P. perennis (L.) Fr. is at least congeneric 
with it. It is therefore to be regarded as a synonym of Coltricia 
S. F- Gray. The living plant was probably unknown to Gray, 
otherwise this mistake would hardly have occurred. 
32. Cerrena S. F. Gray, Nat. Arr. Brit. PI. 1:649. 1821. 
—Founded upon C. unicolor (Bull.) (Dsedalea unicolor (Bull.) 
Fr.), a single species. Synonymous with Agaricus. 
33. Xylomyzon Pers. Mycol. Eur. 2126. 1825.—Based 
on X. lacrymans (Wulf.) and fourteen other species. Merulius 
is cited in synonymy. A synonym of Xylophagus Link proposed 
in 1809. 
34. Cyclomyces Fr. Linnsea 5:512. 1830.— Based on C. 
fuscus Fr. sent to Fries by Kunze in Sieber crypt, exs. n. 63. 
The specimen was already named but the publication belongs to 
Fries. Loxophyllum Kl. Hook. Misc. 2:150. pi. 79, 1831, based 
on L. velutinum Kl. mss., was published only as a synonym of 
Cyclomyces Kze. Klotsch accepted this latter name, which he 
thought existed only in the mind of Kunze, making his own 
manuscript name a synonym; at the same time being ignorant 
of the fact that Fries had published Kunze’s name a year before; 
and apparently not knowing that Loxophyllum had been pro¬ 
posed in 1826 for a genus of the Gesneriacese. 
35. Laschia Fr. Linnsea V: 533. 1830.— At first mono- 
typic, founded on L. delicata Fr., which, according to Patouillard, 
and others, belong to the Tremellacese. 
36. Physisporus Chev. Flor. Par. 1:261. 1836.— Based 
on P. obliquus (Pers.) and eight other species. 
37. Ceriomyces Corda in Sturm, Deutsch. Krypt. FI. 3 :i33. 
t. 61. 1837. — Based on the spurious species, C. fischeri Corda. 
No reference is made here to Ptychogaster, another spurious genus 
proposed by Corda about the same time.
