THE LARGER FUNGI 
BASIDIOMYCETAE. 
1. Basidia simple; spores giving rise to a mycelium 
oil germination . . . . HOMOBASIDIAE. 
2. Basidia longitudinally divided, transversely septate 
or simple; spores producing sporidiola on 
germination HETEROBASIDIAE. 
ASCOMYCETAE. 
Only dealt with incidentally, a few of the larger and more conspicuous 
members being alone considered. 
BASIDIOMYCETAE. 
HOMOBASIDIAE. 
*EU-HOMOBASIDIINEAE. 
Saprophytes. 
1. Hymenium at first covered by a universal or partial 
veil becoming fully exposed at maturity, or 
exposed from the first, spread over the surface of 
gills, pores, or teeth, or over a smooth or rough 
surface Hymenomycetales. 
2. Hymenium enclosed within a peridium at maturity . Gasteromycetales. 
**EXOBASIDIINEAE. 
Parasites. 
3. Hymenium effused, rarely consisting of basidia 
only. Parasitic on leaves, &c Exobasidiales. 
(Not dealt with in 
this Handbook.) 
HETEROBASIDIAE. 
1. Basidia transversely septate, cylindrical, straight, 
or curved Auriculariales. 
2. Basidia longitudinally cruciately divided, subglobose Tkemellales. 
3. Basidia simple, subglobose, with 2-4 very thick, 
stout' sterigmata. Spores producing sporidiola on 
germination Tulasnellales. 
4. Basidia simple, cylindrical, with two long, pointed 
sterigmata. Spores always becoming septate on 
germination, and producing sporidiola Calocerales. 
HOMOBASIDIAE. 
EU-HOMOBASIDIINEAE. 
Hymenomycetales. 
(Comprises the Hyrmenomycetineae, except the Exobasidiaceae, in Engler and 
Prantl.) 
Hymenium spread over the surface of gills or gill-like 
folds Agaricaceae. 
Hymenium lining the inside of tubes, pores, or pore- 
like spaces Polyporaceae. 
Hymenium spread over the surface of spines, granules, 
warts, or other protuberances, the intervening spaces 
fertile. Receptacle fleshy, coriaceous, waxy, crus- 
taceous, or floceose, rarely none ' Hydnaceae.
