FIFTH UPDATE
(May 2011)

Many minor additions and corrections have been made to the printed Checklist published in 2005 (additional new county records, etc.) as well as more substantial changes. These latter changes are noted below (and in four previous Updates, 2006-2009) and include taxa newly discovered in the British Isles, names inadvertently omitted in the printed Checklist, name changes, and a few species which have moved from ‘excluded’ to ‘included’ or vice-versa. Publication references are not repeated where they are already given in the printed Checklist. Suprageneric taxa (families and orders) have not been included in this update pending a review of all CBIB entries.

The database will continue to be updated and major changes will be noted in these pages every year or so.

Occasional but widespread. May be locally common and abundant, especially in southern regions. Current name for orange/brown-capped collections with initially brown stipe squamules and found with a broad range of broadleaved tree partners. The synonymy now includes the oak-associated species previously known in Britain as L. quercinum (note amended authors and reference for this in the synonymy above) and the Salix repens associate L. salicola.

arvinaceus Fr., Cortinarius
Move from ‘included’ list as now regarded as a nomen dubium. Described by Fries as “aurantio-fulvus” in colour but more recently applied to various taxa with yellowish pilei in subgenus Myxacium. Sensu Cooke 732 (737) is for Orton probably C. delibutus. Sensu Rea is unknown. A few more recent records are also doubtful. See FM 10(2): 47 for further discussion.
atratus K.A. Harrison, Phellodon
Move from ‘included’ list. A North American species, not authentically British. Scottish collections named thus are currently assigned (unidentified) to the Phellodon niger complex based on comparative sequencing evidence in Ainsworth et al. [Fung. Ecol. 3: 65-80 (2010)].

Leucopaxillus compactus (Fr.) Neuhoff, Westfälische Pilzbriefe 1(5): 65 (1958)
Remains a nomen dubium, but the synonym Leucopaxillus compactus was omitted from the printed Checklist and entry should be expanded:
Sensu Fries seems near Tricholoma saponaceum. Sensu Neuhoff is Leucopaxillus tricolor. Other Leucopaxillus species have also been suggested. Recorded as British (as T. compactum) by Massee (1911) for reasons unknown in a sense unknown. Hence also listed in Rea (1922).
cumulatum K.A. Harrison, Hydnellum
Move to ‘included’ list.
denudatus L., Clathrus, Sp. pl. 2: 1179 (1753)
Recorded from England (Yorkshire) by Bolton (1789), but his illustration represents a species of the Myxomycota (Arcyria denudata (L.) Wettst.).
exiguus (Pat.) Sacc., Pluteus
Move from ‘included’ list. Not authentically British. Recent revision of collections at K resulted in their redetermination, mostly as P. hispidulus. P. exiguus was included as British by Orton (BFF4: 39) backed by a single collection (1968) he made in Surrey (The Sheepleas) but voucher material named as this could not be traced at K or E. However, an Orton collection was found at E with the required collection details named in Orton’s hand as ‘P. pusillulus?’. Orton stated (BFF4: 39) that the latter species was collected in the Aroid House at Kew and therefore he did not regard it as British. The collection at E (ascribed to The Sheepleas) did not match the original description of P. pusillulus but could not be determined. Since both P. exiguus and P. pusillulus currently lack any known supporting voucher material they are excluded.

helveticus (Singer) M.M. Moser, Chroogomphus, in Gams, Kleine Kryptogamenflora, Edn 3: 51 (1967)
Not authentically British. A British collection of this was described in BFF1: 79-80 but subsequently [BFF1 2nd edn: 113-114 (2005)] regarded as misidentified C. rutilus.
lagopides (P. Karst.) Redhead, Vilgalys & Moncalvo, Coprinopsis
Move from ‘included’ list. Regarded as a nomen confusum to be abandoned. This name was long used for the smooth-spored species now known as C. jonesii. However the type collection was later found to comprise the warty-spored species known as C. phlyctidospora (q.v.).
lanuginosa (Bull.) P. Kumm., Inocybe

Gloeocystidium lapponicum Litsch., Ann. Mycol. 39: 133 (1941)
Not authentically British. Reported from England (Berkshire: Sulham Woods) in 2001 on a fallen fence post but the voucher material at K now redetermined as H. cryptocallimon.
longipes (Boud.) M.M. Moser, Hohenbuehelia
Move from ‘included’ list. Unknown in Britain. The three collections so named in K are misdetermined and probably quasi-stipitate growth forms of H. petaloides. Further details in Henrici [FM 10(4): 135 (2009)].

Move from ‘included’ list (as synonyms of L. scabrum). This is a nomen dubium fide den Bakker & Noordeloos [Persoonia 18(4): 511-587 (2005)] with poorly preserved type material. It has been applied to soft-capped greenish forms of L. scabrum in damp locations and probably also to other species when old, soft and greenish.
murinaceum (J. Blum) Bon, Leccinum
Boletus murinaceus J. Blum
Move from ‘included’ list (as synonyms of L. scabrum). This is a nomen dubium fide den Bakker & Noordeloos [Persoonia 18(4): 511-587 (2005)] as the type is in poor condition and the description could refer to L. melaneum. Some British records probably refer to L. scabrum.
mutatum (Peck) Donk, Hyphoderma
Move to ‘included’ list.
nigricans (Fr.) P. Karst., Phellinus
Move from ‘included’. Not authentically British. “A single confirmed collection from Easterness (Craigellachie NNR) in 1997” recorded on Betula but the voucher material at K now redetermined as Porodaedalea pini on Pinus.
obtusiforme J. Erikss. & Å. Strid, Hyphoderma
Move to ‘included’ list.
percandidum (Vassilkov) Watling, Leccinum
Boletus percandidus Vassilkov, Sovietsk. Bot. 2: 27 (1944)
Boletus versipellis var. percandidus (Vassilkov) Vassilkov, Edible and poisonous fungi cent.Eur. dist. U.S.S.R.: 37 (1948)
Krombholzia aurantiaca f. percandida (Vassilkov) Vassilkov, Notulae Syst. Sect. Crypt. Inst. Bot. Acad. Sci. U.S.S.R. 11: 139 (1956)
Move to ‘included’ list as synonyms of L. versipelle (q.v.).
picinus Fr., Lactarius
Move to ‘included’ list.
poliopus var. alpigenum (J. Favre) Bon, Entoloma, Mycol. Helv. 3(3): 317 (1989)
Not authentically British. Reported from England (Derbyshire: Chatsworth Park) in 2004 but unsubstantiated with voucher material.
pseudoasterospora Kühner & Boursier, Inocybe
Move from ‘included’ list. The type var. was included in CBIB2005 in error. The associated entry should be headed by I. pseudoasterospora var. microsperma (q.v.).
pseudohiulca Kühner & Boursier, Inocybe
Move from ‘included’ list. The only British record was misdet.
pulchrum Lannoy & Estadès, Leccinum
Move from ‘included’ list (as a synonym of L. roseofractum). A synonym of L. rotundifoliae fide den Bakker & Noordeloos [Persoonia 18(4): 511-587 (2005)] unknown in Britain. British collections so named are probably pink-tinged forms of L. scabrum.
pulla (Schaeff.) Gillet, Collybia
Replace notes with: A nomen dubium lacking type material. Antonín & Noordeloos (A&N4 CD) regard this as probably Rhodocollybia prolixa var. distorta. See TBMS 2: 13 (1907) for the description and illustration of the British collection (South Essex: Epping Forest).
pusillulus Romagn., Pluteus, Rev. Mycol. 5 (Suppl.): 23 (1940)
Not authentically British. For further details see ‘excluded’ entry for P. exiguus.
querceus (Britzelm.) Antonín & Noordel., Mycetinis, in Noordeloos & Antonín, Czech Mycol. 60(1): 26 (2008)
Name changed from Marasmius querceus.
relicina (Fr.) Quél., Inocybe
Move to ‘included’ list.
reniformis (G. Mey.) Singer, Hohenbuehelia
Move from ‘included’ list. A nomen dubium. Sensu Cooke [Ill. Brit. fung. 286 (276) Vol. 3 (1883C)] doubtful. The descriptions in Rea (1922) and BFF6 both contain a mix of elements of more than one species. The few British collections require reassessment.
rhodoxanthus (Krombh.) Kallenb., Boletus
Move to ‘included’ list.
rufa (Fr.) Boidin, Peniophora
Move from ‘included’ list. “A single collection from Surrey (Esher, Arbrook Common)” in 1989 recorded on Populus but the voucher material at K now redetermined as P. polygonia.
saccharinus Romagn., Coprinus
Move from ‘excluded’ list and into the new genus Coprinellus.
silvana (Sacc.) O.K. Mill., Hohenbuehelia
Agaricus silvanus Sacc., Michelia 1: 1 (1877)
Pleurotus silvanus (Sacc.) Sacc., Syll. fung. 5: 379 (1887)
Resupinatus silvanus (Sacc.) Singer, Lilloa 22: 253 (1951)
Move to ‘included’ list and add to the synonymy of H. cyphelliformis (q.v.).
stercorarius (Bull.) Fr., Coprinus
Move from ‘included’ list (as a synonym of Coprinopsis stercorea). A nomen dubium applied to several members of the Coprinopsis narcotica complex. Sensu Rea (1922) doubtful. Sensu NCL is Coprinopsis tuberosa (q.v.).
stevensonii (Berk. & Broome) Watling, Gerronema
Move from ‘included’ list. Currently regarded as a nomen dubium. A recent examination of authentic Scottish material at K., originally described as Cantharellus stevensonii, concluded that it belongs in neither Gerronema nor Cantharellus and is probably not identifiable.
stillatitius Fr., Cortinarius
Move from ‘included’ list. Now considered a nomen dubium. For Fries a rare species with cap and stipe coated with blue-violaceous gluten. Orton (1955) noted an unlocalised collection possibly in this sense but “needing further study” and included it in NCL. This name has recently been widely used (e.g. in FN) in a broad sense that includes C. mucifluoides and C. integerrimus (q.v.) of this Checklist. Sensu NCL and auct. mult. is C. mucifluoides (q.v.). C. pseudosalor J.E. Lange, listed as a synonym in the printed Checklist, also now excluded as a nomen dubium as somewhat insufficiently described from a single collection.
storea (Fr.) Bon, Psathyrella, Doc. Mycol. 12: 52 (1982)
Agaricus storea Fr., Epicr. syst. mycol.: 223 (1838)
Hypholoma storea (Fr.) Sacc., Syll. fung. 5: 1033 (1887)
Not authentically British. Sensu Massee (1892) (as Hypholoma storea) doubtful, though H. storea var. caespitosum is Psathyrella cotonea.
tomentosa (Fr.) P. Karst., Onnia
Name changed from Inonotus tomentosus.
trinii (Weinm.) Quél., Inocybe
Delete “and this is otherwise unknown in Britain” from notes.
umbrinum J. Blum, Leccinum, Rev. Myc. 32: 366 (1967)
Omitted from printed list. A nomen invalidum. British records relate to soft greenish forms of L. scabrum collected in wet locations that have sometimes been distinguished as L. molle.
viridis (Alb. & Schwein.) J. Schröt., Amaurodon
Move to ‘included’ list.

UREDINIOMYCETES
convolvuli Castagne, Puccinia
Move to ‘included’ list (q.v.).
saxifragarum Link, Puccinia, in L., Sp. pl. ed. 4, 6(2): 81 (1825)
A nomen dubium, including P. saxifragae Schlecht. and P. adoxae R. Hedw. Sensu auct. brit is P. adoxae.

USTILAGINOMYCETES
deformans Durieu & Mont., Thecaphora
Move from ‘included’ list. Not authentically British. British material, in seeds of Ulex minor, recently recognised as a distinct species T. ulicis (q.v.).
liroi (Lehtola) Nannf. & B. Lindeb., Anthracoidea, Svensk Bot. Tidskr. 59: 205 (1965)
Not authentically British. Reported from Britain in UBI: 15 but no voucher has been traced. There is also a single Scottish collection (1993) at E from Wester Ross (Gairloch) on Carex echinata identified as A. ?liroi which is more likely to be of A. karii.
unedonis Maire, Exobasidium
Move from ‘included’ list. Not authentically British. A single (1984) collection at K on Arbutus leaves from North Essex (Colchester) now redetermined as Aureobasidium sp. Reported from the same vice county in 1961 but unsubstantiated with voucher material.
