Hericium
Inonotus
Basidiomycetes, Aphyllophorales
Inonotus
tomentosus
(Syn.
Polyporus
tomentosa).
Root Rot
of spruce.
Fleshy, branched or unbranched, with subulate
spines long and pendant; spores spherical or
subspherical, staining blue with iodine. Like
Hydnum
but sporophore formed on wood, not
on the ground.
Hericium erinaceus (Syn.
Hydnum erinaceus
),
hedgehog fungus.
White Heart Rot
, occasional
on living oak, maple and other trees. The soft
white spongy rot may entirely decompose the
tissue, leaving large hollows lined with yellowish
mycelium. Sporophores are annual; soft, white,
browning with age, globular with a hairy top and
long slender teeth on the lower surface.
Irpex
Basidiomycetes, Aphyllophorales
Resupinate, effused-reflexed, or shelf-like; youn-
ger parts of hymenophore are poroid; with
increasing age produce flattened teeth.
Irpex lacteus
Wood Rot
and
Decline
of apple.
Gliocladium (Isaria)
Deuteromycetes, Hyphomycetes
Grandinia (Hyphodontia)
Conidiophores equally distributed on a synnema,
erect fascicle of hyphae; conidia hyaline, one-
celled, ovoid; some species in insects.
Gliocladium roseum (formerly
Isaria
clonostachoides
).
Isaria Rot
of tomato. Fruits
are partly covered with cottony mycelium,
white turning pink or orange and becoming gran-
ular, but rot remaining firm. Reported from
around Washington, D. C.
Isaria
Basidiomycetes, Aphyllophorales
Grandinia granulosa (formerly
Hyphodontia
aspera
).
Root and Butt Rot
of spruce.
Hypholoma
Basidimycetes, Agaricales
clonostachoides (see

▶
roseum

Isaria Rot
of tomato.
Margin of cap with a curtainlike veil; stipe with
incomplete or vanishing ring; spores purple.
Hypholoma sublateritium

of currant.
Kluyveromyces
Ascomycetes, Saccharomycetaceae
Idriella
Kluyveromyces marxianus var.
marxianus
Soft Rot
of onion caused by a true
yeast on bulbs.
Deuteromycetes, Hyphomycetes
Mycelium hyaline to brown; conidophores
brown, simple, nonseptate, narrowed above,
with prominent spore scars; conidia
(sympodulospores) lunate to falcate, with pointed
ends, produced in clusters near apex of the conid-
iophore; aleuriospores brown, several-celled.
Idriella lunata
Root Rot
on strawberry.
