18. A. comuvioides Kacib., in liedw., xxviu,, p. 123 (1889). 
Sporangia bright cinnamon, obovate on short stalks ^ mm. high, 
or almost sessile and globose, 0*5 mm. diam., frequently confluent 
into irregular sessile plasmodiocarps, 3 mm. long, ^ mm. high ; 
wall persistent in th'e lower part in the stalked forms as a flat 
cup marked with beautiful net-like thickenings on the inner side; 
capillitium threads 3 to 8 yu, diam., much branched and anasto- 
mosing with few free ends, with band-like thickenings, either 
united to form a net, or scalariform, section of threads triangular 
or flattened ; band-like thickenings not so regiilar as in A. 
Jerruginea, much higher, often cvirved and suddenly dLsappearing; 
spores cinnamon in mass, smooth, 6'5 to 8"5 diam. The markings 
of the capillitium show near approach to A. ferruginea and A. 
inei'mis, and one might unite all three into a collective species : 
A. ferruginea has smooth spores 11 to 12 yu,, ^. inermis Rac. has 
the spores 10 to 12 /a, minutely warted.

Genus 38.— LACHNOBOLUS Fries, Fl. Scan., p. 356 (1835). 
Sporangia sessile, clustered ; sporangium-wall single, persistent, 
not thickened with angular granules ; capilUtium a loose network 
of cylindrical threads, with thickenings in the form of closely 
set warts. 
1. Laelmobolus circinans Fries, Suipma Veg. Scand., ii. (1849). 
Plasmodium? Sporangia 'subglobose, sessile, clustered, 0'5 to 0-8 
mm, diam., ochraceous-brown, shining ; sporangium-wall mem- 
branous, firm, papillose, ochraceous-yellow. Capillitium a network 
of freely branching, ochraceous-yellow threads, 2 to 5 /x, diam., 
closely and equally beset with prominent warts ; attached at 
numerous points to the sporangium-wall. Spores pale yellow, 
almost smooth, with a few scattered warts, 6 to 8 /a diam. —
