(23 pictures)

xylaria1.jpg (3493 bytes) Sphaeriales - Xylaria - compound perithecial ascoma transversely bisected, showing peripheral perithecial cavities. 
   X 4
xylaria2.jpg (7114 bytes) Sphaeriales - Xylaria - section through a single perithecial cavity.  The dark lines are asci each containing a single row of 8 black ascospores
  X 100
hypox1.jpg (9266 bytes) Sphaeriales - Hypoxylon pruinatum causing poplar canker.  The canker is vertically elliptical in outline, and the clustered ascomata of the parasite develop only after the outer bark has fallen away (see below)
    X 1/8
hypox2.jpg (11636 bytes) Sphaeriales - Hypoxylon pruinatum causing poplar canker.  The round, whitish patches are clusters of perithecial ascomata.  
    X 1/4
sord1.jpg (6514 bytes) Sordariales - perithecial ascoma of Sordaria, a dung-inhabiting genus with dark, non-appendaged ascospores.  Note that the neck of the perithecium is phototropic (grows toward the light).      
    X 100
sord2.jpg (5339 bytes) Sordariales - Sordaria - asci, part of a perithecial squash (phase contrast illumination).  
    X 400
podos1.jpg (5551 bytes) Sordariales - perithecial ascoma of Podospora, another coprophilous (dung-inhabiting) genus.
    X 100   (also see next 3 pictures)
podos4.jpg (5480 bytes) Sordariales - two asci of Podospora tarvisina, each containing 128 ascospores (a multiple of 8).  
       X 250
podos2.jpg (2833 bytes) Sordariales - a single ascospore of Podospora, with a primary (tubular) appendage and two secondary (gelatinous) appendages. 
    X 700   (phase contrast illumination)
podos3.jpg (4200 bytes) Sordariales - a single ascospore of Podospora, with a primary (tubular) appendage and several secondary (gelatinous) appendages at both ends.  (phase contrast illumination)
    X 600
chaetom.jpg (6412 bytes) Sordariales - a perithecial ascoma of Chaetomium, with coiled apical appendages (looks like a bad hair day!).
    X 50
diatrype.jpg (9658 bytes) Diatrypales - compound perithecial ascomata of Diatrype disciformis in bark.  
     X 2
diatryp2.jpg (6509 bytes) Diatrypales - oblique section through superficial stroma and perithecial ascomata of Diatrype on wood.
     X 10
diatryp3.jpg (6861 bytes) Diatrypales - asci of Diatrype containing small sausage-shaped (allantoid) ascospores 
     X 400
nectria2.jpg (2978 bytes) Hypocreales - clustered bright red perithecial ascomata of Nectria cinnabarina 
     X 50
nectria1.jpg (6716 bytes) Hypocreales - coral spot caused by the Tubercularia anamorph of Nectria cinnabarina  X 1/2
If you want to find other anamorph-teleomorph connections, you can look them up at - http://gause.biology.ualberta.ca/jbrzusto/anateleo/anatel.html
Enter Nectria and see how many different anamorphs you retrieve. Try Acremonium and see how many teleomorphs come up. Why do you think there are so many?
nectria3.jpg (4380 bytes) Hypocreales - anamorph + teleomorph of Nectria cinnabarina
     X 50
gibber1.jpg (4870 bytes) Hypocreales - Fusarium graminearum anamorph of Gibberella attacking grain. 
gibber2.jpg (8341 bytes) Hypocreales - Fusarium anamorph (pink) + Gibberella teleomorph (black) on corn (Zea mays)
     X 40
hypomy1.jpg (7764 bytes) Hypocreales - Hypomyces lactifluorum (orange) attacking and completely covering a fruit body of Lactarius.   (see next two pictures)
   X 1/2
hypomy2.jpg (5061 bytes) Hypocreales - vermilion stroma of Hypomyces lactifluorum suppressing gill formation in Lactarius.   
     X 3
hypomy3.jpg (6899 bytes) Hypocreales - bright orange/red  perithecia of Hypomyces lactifluorum sitting on the stroma which covers the surface of the Lactarius.
   X 100
hypocre1.jpg (6973 bytes)  

Hypocreales - stromata of Hypocrea on wood.  The darker dots are the ostioles of immersed perithecia.   
     X 25.
