Although the morning of the event was bright and sunny, only 13 people attended this foray which was led by Brian Spooner. A sad notion whispered everywhere prior to the day, that continuous dry weather in previous months had produced little, may have been the cause. Nevertheless, Arbrook Common gave us one of the longest day-foray 5 species lists to date (see below). This is no doubt due to the wetness of the Common, which is largely over-exposed, water-retentive London clay, instead of sandy soil as in the other sections of the Esher Commons. Dick Alder, Ross Baker and Lynn Whitfield joined the ENHS team; we all enjoyed the day.
Brian showed us many fungi along the small valley amid Arbrook, which pleased us all, including toadstool-hungry guests from as far afield as London, Sussex and Turkey. After a two-hour morning stroll, my notebook had become full with records of over 100 species of fungi, including well over 40 toadstools. Most of the mycorrhizal toadstools had passed their best, but some remained identifiable. A small Amanita, later named A. olivaceogrisea, was particularly pleasant and a new record for the site. he small stream with an alder carr was also surrounded with herbaceous plants, so that numerous microfungi - rusts, powdery mildews and other Ascomycetes on herbaceous stems - were recorded. The collection boxes and bags were full. Back in the laboratory, although Brian went through a pile of leaves very quickly, it took me two full weeks to examine most of my own collections. A mould which grew on a rotten Scleroderma fruitbody has been identified by Dr Punithalingham as Gliocladium penicillioides (cf.), an interesting but difficult subject to pursue.
In the afternoon of the day, Brian led the eager few into yet another section of Esher Common, EC North, adjacent to and to the west of Arbrook Common. Only 30 yards apart from Arbrook Common, this section is strikingly different in its soil formation, sandy and well drained. First we chose a wet remnant of Sphagnum bog, with its moist edge covered with grasses, rushes and birch saplings apparently trimmed down by the management. Curiously we saw one hemp plant growing here, but we left it untouched for the management to deal with, as it seemed to have no microfungi associated with it. This venture and a short stroll afterwards through a dry heathland area added two dozen species to our list. A small yellow disc fungus on woodchips, collected by Vivien Hodge, has been considered closely related to Phelotium monticola, a not uncommon fungus but with taxonomic complications, which Brian and I are still investigating. One forayer visited a small section of EC South, too, and collected two additional fungi.
In total, 187 species of fungi (and one var.) were named and recorded for the day, 160 of which are from Arbrook Common. Six new species have been added onto the ever growing Esher list. Two slime moulds (non-fungi, Protozoa) were also recorded.
