Chapter XVI: Appendix: B

-------

The following species, belonging to those sections of Microscopic Fungi which are included in this volume, have been found in Britain since the publication of the preceding Appendix:—

=Peridermium columnare=, Alb. and Schw. Simple, slender, naked, cylindrical, elongated, lacerated at the apex, white; sporidia orange.—On _Picea_. Watcombe, near Torquay. September, 1867. (_E. Parfitt._)

* * * * *

=Æcidium Orchidearum=, Fiedl. ORCHIS CLUSTER-CUP; spots large, pallid, orbicular or elongated; peridia circinating, semi-immersed; spores golden-yellow.—On _Orchis latifolia_. Dilham, Norfolk. June, 1866.

* * * * *

=Puccinia discoidearum=, Link. SOUTHERNWOOD BRAND; spots obliterated; sori subrotund, minute, surrounded by the ruptured epidermis; sporidia brown, oblong or ovoid, somewhat rhomboidal, with both cells attenuated, and triangular; peduncles elongated.—On _Artemisia maritima_. Swanscombe Marshes. 1865.

=Puccinia Virgaureæ=, Lib. GOLDEN-ROD BRAND; spots orbicular, pallid, then yellowish; sori blackish-brown, minute, punctiform, shining, clustered, nearly stellate, convex; sporidia oblong, subconstricted, yellowish-brown above, attenuated and yellowish-white below; peduncles short.—On leaves of _Solidago virgaurea_. Shere, Surrey. July and August, 1865. (_Dr. Capron._)

=Puccinia difformis=, Kunze. GOOSEGRASS BRAND; spots yellowish; sori variable, compact, often in rings; epidermis bullate; sporidia obovate, obtuse, on short pedicels, brown.—On leaves of _Galium aparine_. July, 1866. Shere and Darenth Usually occurring on or near spots previously occupied by _Æcidium_.

=Puccinia Apii=, Corda. CELERY BRAND; sori large, confluent, red-brown, powdery; spores oblong, constricted, brown; epispore smooth, thick; pedicels short, attenuated.—On leaves of Celery. Autumn, 1866, 1867.

Bettws-y-coed, N. Wales. July, 1866.

=Puccinia Mœhringiæ=, Fuckel. It is very doubtful whether this deserves to rank as a species distinct from _P. Lychnidearum_, Lk. I think not. The sporidia are rather shorter than in the last-named species, and the pedicels are very long; otherwise it does not appear to differ from the typical form.—On _Mœhringia trinervis_. Near Worcester. June, 1867. (_Dr. Holl._)

VETCH BRAND; sori few and small, scattered, intermixed with pustules of _Trichobasis_; sporidia obovate, on rather long pedicels, of a tawny colour, and slightly constricted at the septum; epispore smooth.—On leaves of _Vicia sepium_.

September. Not uncommon.

* * * * *

Shere. October, 1865. (_Dr. Capron._)

KNOTGRASS RUST; cauline; sori elongated and confluent, convex, surrounded by the remains of the ruptured epidermis; sporidia subglobose or globose, smooth, yellowish-brown; pedicels very long, thickened, hyaline, persistent. _Capitularia Polygoni_, Rabh.—On the stems of _Polygonum aviculare_. October. Common.

* * * * *

=Cystopus spinulosus=, De Bary. THISTLE (WHITE) RUST; conidia in time much elongated; sori erumpent on both surfaces of the leaves, white; oospores globose; epispore brown; tubercles minute, solid, very prominent, often acute and spinulose.—On Thistles. Bungay, Suffolk. September, 1865.

ADDENDA.

-------

[The following species have been added to the British Flora since the
publication of the Appendix.]

=Æcidium Parnassiæ=, Grav. PARNASSIA CLUSTER-CUPS; hypophyllous; spots pallid; peridia in subrotund patches, irregularly disposed, tawny-yellow, between urceolate and concave; the margin thick and nearly entire; spores pallid. _Duby. Bot. Gall._ ii. p. 904.—On leaves of _Parnassia palustris_, near Glasgow. (_Dr. Greville._) The original specimen is in the Edinburgh Herbarium.

=Æcidium Statices=, Desm. SEA-LAVENDER CLUSTER-CUPS; hypophyllous; spots subrotund, or confluent and irregular, purple; peridia in subrotund circinating clusters, sometimes irregularly disposed on the nerves and petioles; urceolate; margin lacerated, white; spores orange. _Desm. Exs._ No. 132. _Cooke, Exs._ No. 444.—On leaves and petioles of _Statices_. June, July. Fleetwood, 1859 (_Rev. A. Bloxam_). Walney Island, Lancashire, 1871 (_C. Bailey_). Near Basingstoke, 1871 (_R. S. Hill_). Near Chichester, 1872 (_F. V. Paxton_).

=Chætomium funicolum=, Cooke. TWINE BRISTLE-MOULD; perithecia scattered, sub-ovate, black; hairs of the vertex very long, dichotomous or simple, erect, slender, acute, black; sporidia lemon-shaped, dingy brown.—On twine suspended in a vessel containing water at the British Museum. (_W. Carruthers, F.R.S._) March, 1872. This species is most closely allied to _C. elatum_, but much smaller and neater. It is wholly black, and without the fibrous base of _C. elatum_. The hairs are more delicate, not having half the diameter, and the sporidia are scarcely more than half as long or broad. A species of _Polyactis_ afterwards made its appearance on the same mycelium on some portion of the twine left behind with a few immature perithecia.
