THE TINTERN FORAY. April 24th to 28th, 1925.

By E. M. Wakefield, M.A., F.L.S.

THE Spring Foray was held at Tintern froin April 24th to April 28th, with headquarters at the Beaufort Arms Hotel. About fifteen members assembled during the evening of the 24th, some having already been out and gathered a few species, chiefly of micro-fungi.

On Saturday morning a start was made at 10 a.m. for the woods lying north of Tintern. I t was soon apparent that the larger fungi were extremely scarce, probably owing to the prevailing cold, dry winds, and that the list would have to be made up chiefly of micro-forms. Along the hedge bank of a narrow lane leading upwards behind the village were found several Rusts, including Puccinia tumida on Conopodium, Milesina ScoloPendrii on the hart's-tongue fern, and Milesina Polystichi on Polystichum angulare. The two latter species, and also M . Kriegeriana on the male fern, were found in some abundance throughout the foray, and it is interesting to record that M . Scolopendrii and M . Kriegeriana had also been found to be abundant in South Devon just a week earlier. In a coppice near the top of the hill a very fine specimen of Dermatea Cerasi was obtained on dead branches of Prunus Avium.

On Sunday morning some of the members spent a short time in a wood beside the railway on the Gloucestershire side of the River Wye. This wood was very damp in the lower part, near the river, and consequently some of the larger Discomycetes were found here, which did not occur elsewhere during the foray. Mitrophora hybrids was soon noticed, and Miss Brett later picked up a fine specimen of Disciotis venosa. Both Ciliaria scutellata and C. trechispora were also found. Dead twigs, of willow and ash chiefly, yielded various Pyrenomycetes, and also Propolis faginea.

In the afternoon the whole party walked to Wyndcliff, obtaining on the way two interesting Discomycetes growing on the dark basal part of dead stems of Pteris, namely Micropodia Pteridina, and a pale yellowish form somewhat resembling Helotium cyathoideum, which was subsequently identified by Mr W. D. Buckley as probably Dasyscypha caulicola (Fr.) Boud., about which little seems to be known. Dr Malcolm Wilson secured Synchytrium Mercurialis and later S . Taraxaci. On the descent from the Wyndcliff some very fine specimens of Daldinia concentrica were noted.

6 Transactions British Mycological Society. On Monday morning the woods on Chapel Hill were visited.

The ground here was very dry and little of interest was obtained. In a small marshy spot at the bottom of the hill some deqd giant Heracleums were found, whose stems were covered with fine fructifications of Heterosphaeria Patella, unfortunately however with the asci as yet immature. One small dead twig, unidentified, yielded a few perithecia with the characteristic spores of Leptospora caudata Fuck.

The party returned home for lunch and in the afternoon another visit was paid to some of the ground covered on Saturday, which so far had proved most productive, the return being made by way of Barbados Hill.

Here Miss Roper found a plant or two of Jasione montana showing blackish pustules on the leaves, which to the naked eye appeared like one of the Rusts. Microscopic examination showed however that the fungus resembled the early stage of certain Discomycetes. Unfortunately it was quite immature, but the species if found again may prove to be Pyrenopeziza Jasiones Romell, which would be a new record for this country.

Taphridium umbelliferarum occurred scantily in a hedge, and towards the end of the walk a mass of dead stems of broom yielded Nectria sanguinea, N. mammoidea and Volutella ciliata, all in considerable abundance. Ivy leaves which were brought back with Phyllosticta hedericola and Septoria Hederae, later produced also Vermicularia trichella and Mycosphaerella hedericola.

A short business meeting was held on the Monday evening, with Mr Pearson in the chair. The President, Mr Cheesman, sent apologies for his absence through ill-health, and best wishes for the success of the meeting. A letter was read from Dr Durham, President of the Woolhope Club, expressing a hope that the Society would find it possible to hold a foray in conjunction with the Woolhope Club, some time in the near future. As the 1925 Foray was already fixed for Dublin, and an alternative foray was considered not practicable, it was decided that the General Secretary should be asked to write to Dr Durham suggesting that the Autumn Foray in 1926 might be held at Hereford.

The locale of the next Spring Foray was also considered, and after some discussion members voted in favour of Arundel if possible, or if not some other convenient spot in the South Eastern district.

Two new members, Dr 0. F. Burger of Gainesville, Florida, and Mr W. F. Hanna were elected, and the meeting closed with hearty votes of thanks to the Commissioners of Woods and Forests and to Mr Hastings Clay, for permission to work over their lands.

LICHENS OF THE TINTERN FORAY. By H. H. Knight, M.A.

T H E rocks in the Tintern district were similar to those met with at the Spring Foray at Matlock last year. In both districts Carboniferous Limestone rocks occur, but instead of the Mill- stone Grit of Derbyshire we had Old Red Sandstone rocks. The Wye Valley at Tintern however is well wooded, and consequently calcareous lichens were less plentiful than in the exposed valleys of Dovedale and Millers Dale. The most interesting find was O$egra$ha $araxanthodes, a lichen of shady calcareous rocks.
