trichospores grow. In this genus the appendages become visible before the exogenous trichospores begin to
2. Genistelloides helicoides (RMBL-M-17): Released trichospore with two coiled appendages. Appendages may
function to restrain spores from drifting downstream, thus retaining them in the vicinity of the host
population and leading to possible ingestion and germination in the insect gut.

(as indicated) Supplied by Meredith Blackwell:
I. Fungi and Arthropods: Some fungi from complex associations with arthropods. These may be parasitic, mutualistic, or often spore dispersal related.
1. Section through the basidioma of the polypore Ganoderma. The pores, some of which are filled with
basidiospores, are seen in longitudinal section. The large hole was made by a ciid beetle which lays its
eggs in the polypore. (M. Blackwell)
2. Antennopsis: a minute conidial fungus known only on termites (SEM). (M. Blackwell)
3. Septobasidium: a basidiomycete, parasitizes a few aphids while providing a home for most of the colony.
4. Laboulbenia on a legionary ant, Eciton. The many species of Laboulbeniales are obligate parasites of insects,
mites, and a few millipedes. (M. Blackwell)
5. Pyxidiophora perithecia, one of which (in the center) has exuded the ascospores of a single ascus.
6. Pyxyidiophora perithecia. Higher magnification of a perthecium of with ascospores visible at the base of the
perithicium. (M. Blackwell)
7. Pyxidiophora ascospores. Ascospores of Pyxidiophora species develop a dark holdfast region which attaches to
mites and insets. The dark spots on the mite are the holdfasts. (M. Blackwell)
8. Anamorphs of Pyxidiophora. Anamorphs of Pyxidiophora developed directly from ascospores on mite ventral
surface. Notice dark holdfasts and beginning of conidium production. (M. Blackwell)
10. Synchytriumpapillatum infection induces production of a red pigment by the desert plant Erodium cicutarium.
11. Rhizophidium on pine pollen. (R.L. Gilbertson)
12. Phlyctochytrium rhizomycelium. (M. Blackwell)
13. Phlyctochytrium zoospores within a zoosporangium. (M. Blackwell)
14. Gametangia of Allomyces. The larger female gametes are being released from one female gametangium; the
male gametangia are terminal in this species. (M. Blackwell)
15. Resting sporangium of Allomyces. Showing the pitted pigmented cell wall. (M. Blackwell)
16. Developing asci of Balansia epichloe, an endophyte of grasses. Ascongonial hyphae with crozirs are visible.
Giemsa stain showing nuclei in deep blue. (J.P. Jones)
17. Young ascus with four of eight ascospores visible in the section (TEM). (C.W. Mims)
18. Ascus slightly older than slide 17. Note thicker ascospore walls (TEM). (C.W. Mims)
19. Ascus with mature ascospores with ornamental walls (TEM). (C.W. Mims)
20. Immature tailed ascospores in an ascus (Echinopodospora). (J.P. Jones)
21. Muriform ascospores at tip of "Jack-in-the-box" ascus (Leptosphaerulina). (M. Blackwell)
22. Sordaria crossover experiment. Results of an experiment on meiotic crossover using ascospore color as a
genetic marker. (M. Blackwell)
23. Taphrina deformans. Showing early stages of infection of peach leaves; the disease is call peach leaf curl and
the symptoms are brought about partly by fungus production of plant growth regulators. (J.P. Jones)
24. Cleistothecia of a powdery mildew of lilac leaves. The fungus reproduces asexually until late summer when it
forms appendaged ascomata. (M. Blackwell)
25. Crushed cleistothecium (as in slide 24). Asci containing four ascospore have been released. (M. Blackwell)
26. Stromata with pertithecia of the fungal endophyte Atkinsonelli on the grass Danthonia. Endophytes grow
between the plant cells, and some convey insect resistance to the plants. (J.P. Jones)
27. Tuber, a truffle that grows in an obligate association with some tree species. These ascomata
are derived apothecia of the hypogenan fungus. Cut ascomata show the convoluted hymenial area.
28. The Cylindrocarpon asexual stage of Calonectria showing nuclei. ( J.P. Jones)
29. Helicosporium is names for its coiled conidia. (J.P. Jones)
30. Mycelium and developing conidiophores of Aspergillus nidulans (SEM). (C.W. Mims)
31. Nematode trapped by a conidium-producing mycelium. The nematode is held by fungus nooses and eventually
digested. The fungus thus supplements its nitrogen supply. (E. McGawley)
32. Mycelium of a wood decaying basidiomycete. Notice the droplets of exudate produced by the mycelium. This
mycelium also produces extracellular enzymes that help to digest the cell walls of the wood.
33. Dolipore septum. An elaborate septal pore structure, the dolipore septum, is characteristic of the mycelium of
most basidiomycetes. (C.W. Mims)
34. Developing basidia and basidiospores. This type of sexual reproduction is the hallmark of the basidiomycetes.
35. Amanita muscaria mushrooming through soil beneath a pine tree. These ectomycorrhizal fungi are also known
for producing hallucinogenic compounds.
36. Ectomycorrhizae formed by a basidiomycete and Helianthanum.
37. Basidiome of the polypore, Laetiporus sulphureus. This fungus decays living trees by selectively degrading
cellulose from the wood cell walls and leaving behind brown lignin residue. This type of decay is known
as brown rot. (M. Blackwell)
38. Inonotus dryadeus. Inonotus dryadeus produces golden droplets that appear to have antibiotic activity against
certain bacteria. This photograph was taken at night when slugs feed upon the basidiome tissue.
Basidiospores are produced in pores on the underside of this root rot basidiomycete.
39. Rust life cycle. In addition to the more familiar mushrooms and polypores, many other fungi produce basidia.
One such group is the rust fungi that are parasites of plants. Rusts have complex life cycles, some
involving two unrelated host plants and a variety of spore types besides basidiospores, as shown in the
diagram. (C.W. Mims)

6. Lobaria linita, cross section of thallus showing upper cortex, green algal layer, and cyanobacterium (Nostoc sp.)
in cephalodium (duller green below).
7. Ectomycorrhiza, cross section. Russulaceous mycorrhiza on Tsuga heterophylla (western hemlock). Mycorrhiza
diameter is approximately 1/2 mm. This low magnification view shows the mantel of hyphae surrounding
the host root.
8. Ectomycorrhiza, cross section, enlarged. This higher magnification shows the Hartig net surrounding cortex
cells, in one case being sections in "face view" in its position between cells "in front" and "behind" the
