I have been unable, however, to obtain authentic material of I. xanthodisca. According to Huijsman (pers. comm.) who studied material from Bresadola's herbarium at S, I. geophylla var. lutescens is identical with I. posterula. 2) Inocybe posterula often resembles I. geophylla (Fr.: Fr.) Kumm., but can be recognised by the less sericeous-smooth and more yellow pileus, the more robust habit, and the spores with a more conical apex. The latter character, however, is rather diffucult to observe, as the apex of the spore of I. posterula is only slightly conical. Inocybe phaeodisca var. geophylloides Kuehner differs in slender habit, stipe with reddish tinges at apex, and somewhat longer spores. Its ecology is somewhat different too.","Kuyper, Thomas W. 1986.

I. striata has had much the same status in southern Europe. It appeared conspecific with I. proximella in our examinations, as did I. umbrinodisca. We thus reduce these to synonyms. We have not studied the type of Inocybe striata, but have relied on type descriptions by Bresadola (1927-33) and Bizio and Marchetti (1998), and considered how the Bizio's collections agree with these descriptions. Bizio sent us four recent collections of I. striata that we subjected to ITS analysis. Of these, two Italian and the Croatian specimen agreed in cystidia and reasonably well in spores with the type descriptions of I. striata, as well as with I. proximella. They deviated from the type of I. proximella in their ITS sequences by one or two bases and a gap of three bases (GenBank JN580841, JN580842, JN580843). However, the Croatian and an Italian sequence were identical with some other Finnish sequences of I. proximella. Compared with the type, all the other I. proximella sequences had the same gap of three bases including a collection of Karsten from 1895 (from that collection only the ITS1 succeeded - JN580844). The fourth analysed specimen sent by Bizio from Italy had shorter fusiform cystidia and spores with smaller, irregular nodules, and it diverged greatly in the ITS from the I. proximella type, representing an unknown species. In further support, Bizio and Marchetti (1998) mentioned that the stipe bases of the type fungi of I. striata were ochraceous. This fits our observations of I. proximella. According to Stangl (1976), both Inocybe striata and I. striatorimosa P.D.Orton possibly belong to the I. acuta complex. We have studied a part of the holotype of I. striatorimosa (K). This belongs to the I. soluta Velen. complex, differing from all the species we describe here. The ITS2 sequence of I. umbrinodisca failed, but the ITS1 was identical with most Finnish sequences of I. proximella. Microscopic and macroscopic features and habitat information agreed, except that the odour of I. umbrinodisca was mentioned as fruity acidulous or at times subpelargonious (Kuehner 1988). Kuehner collected I. umbrinodisca under Picea. In conclusion, Inocybe proximella is a rather variable species with a wide distribution. It has typically a rather robust appearance, a weakly fibrillose and rather pale, grey brown cap, often a yellow to ochre tinge at the stipe base, and fairly large spores with rather large nodules. It is likely that it is the most common of all species treated in this paper. However, it is not a common species in Finland. It can be confused with I. silvae-herbaceae, for example. See our comments about I. silvae-herbaceae for comparison. The ITS sequences of the examined one Swedish and 20 Finnish collections of I. proximella, excluding the type, were identical (JV26381 in the phylogram - GenBank JN580845), except for one base difference in collection JV15349 (JN580846), and an insertion/deletion of one base in two specimens (JV21832 - JN580847, KK223/08 - JN580850). An Estonian (JN580848) and a Norwegian (JN580849) specimen both differed by one (different) base from most Finnish specimens. I. proximella is rather closely related to I. giacomi: the ITS sequences of I. giacomi deviated by 22-23 bases and 5 insertions/deletions from the sequence of I. proximella type.","Kokkonen, Katri; Vauras, Jukka.

I. studied several collections in his herbarium (e.g. Romagnesi 73.33 & 74.147) which corresponded in all respects to Heim's protologue of I. halophila. 2) Inocybe pruinosa differs from the North American I. bulbosa Peck (in Bull. Torrey bot. Club. 36: 333. 1909) in having somewhat smaller cystidia, larger spores and an (almost) equal stipe. Inocybe longispora M. Lange (in Medd. Groenland 148: 13. 1957) shows some superficial resemblance to I. pruinosa but differs in narrower spores (4.5-5.5 microns broad), less thick-walled pleurocystidia and a stipe that is pruinose over only 1/10th of its length.","Kuyper, Thomas W. 1986.

The spores are smaller, 8.0-13.5 x 6.5-11.0 microns, on average 9.3-11.3 x 7.5-9.4 microns and Q = 1.1-1.3. Furthermore, the nodules are not as regular as in I. lacunarum, but there are also some crown-shaped double nodules. Pleurocystidia are shorter and narrower, 34-60(-71) x 12-15(-19) microns, as also the caulocystidia at stipe apex, which are 28-48 x 12-17 microns.

Kauffman must have had in hand unusually pale specimens (Smith, A. H. 1939. Certain species of Inocybe in the Herbarium of the University of Michigan. Papers Mich. Acad. Sci., Arts Letters 24 : 93-106; p. 103) with more than the ordinary amount of white superficial layer on the pileal surface. This, in conjunction with his ambiguous description of the odor, has made his species rather difficult to recognize in the field. Actually, in our experience, I. lanatodisca is of widespread occurrence and often abundant locally, but it is usually much darker than "" pale ochraceous brownish "" or "" pale tawny "" (quotes from Kauffman 's description), and its odor is much more characteristic than merely "" nauseous "". The odor is complex, with three main components : green-corn, spermatic, and fragrant (sweet-aromatic). Usually the green-corn component is strongest when the specimen is collected, but fades subsequently, and the fragant component becomes more evident. The white superficial layer on the pileal surface varies considerably in amount from one collection to another, and is frequently absent altogether, giving the pileus a decidedly different appearance from that stressed in the original description. We cannot agree with Heim 's contention (Heim, R. 1931. Le genre Inocybe. Encyclopedie Mycologique I. P. Lechevalier & Fils, Paris. 429 p.; p. 197, 395) that I. lanatodisca is a synonym of I. maculata Boudier. Where the two species occur together they are readily distinguished.

Inocybe langei has often been confused with I. hirtella Bres. var hirtella, e.g. by J. Lange (Fl. agar. dan. 3: 78. 1938), but the latter species has a more squamulose pileus, whitish lamellae, a different smell and slightly larger spores. Spores measurements as given by the Danish author are, however, often somewhat too small and this might explain Lange's misinterpretation.","Kuyper, Thomas W. 1986.
