Ti allego il pdf dell'articolo con il quale vengono descritti 7 generi appartenenti alla famiglia
Inocybaceae. In Europa sono rinvenibili quattro di essi (
Inocybe s.s., Mallocybe, Inosperma, Pseudosperma), più un quinto (
Tubariomyces) piuttosto raro. Altri due generi (
Nothocybe, Auritella) sono extra-europei.
Di seguito la chiave di distinzione dei generi.
TAXONOMIC KEY TO GENERA OF INOCYBACEAE
1. Pleurocystidia present, or, if absent, then basidiospores nodulose or long projectile-shaped
…………………………………………….
Inocybe
1′. Pleurocystidia absent and basidiospores smooth
and globose, elliptic, (sub)amgydaliform, (sub)
phaseoliform, or weakly angular in outline …… 2
2. Stipe apex pruinose, fibrillose, furfuraceous, or
flocculose; basidiomes not changing color, basidia
hyaline (not necropigmented) ………………… 3
2′. Stipe apex smooth or basidiomes rubescent or
brunnescent or basidia necropigmented ……… 4
3. Spores elliptic or indistinctly phaseoliform; widespread and associating with numerous diverse
plant genera but not Acacia; cheilocystidia without resinous substance ……………
Pseudosperma
3′. Spores phaseoliform to ovate-elliptic, at times with
weak angular outline; known only from tropical
India in association with Acacia; cheilocystidia
with resinous substance ………………
Nothocybe
4. Pileus rimose and stipe smooth; basidia hyaline
and not slender (Q < 4.0) …………
Inosperma
(including Maculata clade)
4′. Pileus tomentose, woolly, squarrose, or pitted and
stipe not smooth; basidia necropigmented and
slender (Q > 4.0) ………………………………… 5
5. Basidiomes small and with distant decurrent or
adnate lamellae (habit tubarioid, omphalinoid), pileipellis a palisade of subhymeniform hyphae, stipe
with caulocystidia entire length ……
Tubariomyces
5′. Basidiomes not small (habit tricholomatoid) and
lamellae close, pileipellis various in structure but
stipe lacking caulocystidia the entire length … 6
6. Basidiomes rubescent and usually with distinct
odor like fish, old wine caskets, bruised geranium
leaves, or earthy ……… Inosperma (including
Inocybe sect. Cervicolores)
6′. Basidiomes brunnescent or not staining where
bruised; odor, if present, like honey, unpleasant,
or not as above ………………………………… 7
7. Cheilocystidia >50 µm (or absent if sequestrate)
and thin-walled and hyaline in Australian taxa or
as pyramidal, pigmented, thick-walled chains in
Afro-Indian taxa; occurring in African rainforests, Indian wet evergreen forests, and in seasonally dry tropical sclerophyll and temperate areas
of Australia ……………………………
Auritella
7′. Cheilocystidia often <50 µm, thin-walled, and hyaline, but in few species articulated as short chains or
brown-incrusted but never arising as pyramidal
chains; if cheilocystidia >50 µm long, then from
temperate regions; predominant in temperate
regions of the Northern and Southern
Hemispheres (Australia, New Zealand), less diverse
in seasonally dry tropics of Africa and Australia and
tropical forests of south Asia ……………
