S p o r o tr ic h um sulphureum, Grev. in Wern. Trans, v. 4. p. 69. t. 5. f. 3__
Ejusd. Fl. Edin. p. 465.
H ab. On dung, damp wood, &c. Also on damp corks and other substances
m vaults and cellars. Frequent at all seasons in Edinburgh.
Tufts half a line to 2 lines broad, irregular in form, mostly roundish, o f a
pale yellow or sulphur colour; distinct, at length sometimes confluent.
Filaments branched unequally, often abruptly, jointed. Sporidia globose,
small, numerous, sulphur-coloured.
I have not been able to find any described species answer-
able to the present individual, which, from its colom-, is sufficiently
striking at first sight. The Byssoidece deserve to be
more studied, not only from the intrinsic beauty of the greater
number, but from the satisfactory characters which these plants,
small as they are, furnish to an accurate observer.
