Fig. 34 Sessiliospora bicolor (IMI 4101 lc—holotype). often forming long prostrate chains of 10 or more cells, determinate, short-cylindrical or barrel- shaped, dark brown, smooth-walled, mainly 8-10 urn long and 4-5-6 urn wide, with a distinct lateral scar on the dorsal face which is oval, subhyaline, and 1-1-5 |im diam.

. Bulletin of the British Museum (Natural History) Botany. 252 D. L. HAWKSWORTH. Fig. 34 Sessiliospora bicolor (IMI 4101 lc—holotype). often forming long prostrate chains of 10 or more cells, determinate, short-cylindrical or barrel- shaped, dark brown, smooth-walled, mainly 8-10 urn long and 4-5-6 urn wide, with a distinct lateral scar on the dorsal face which is oval, subhyaline, and 1-1-5 |im diam. Conidia solitary, dry, pleurogenous, acrogenous, elongate-obclavate, 3-4 septate, smooth- and thick-walled, portion excluding the terminal cell dark brown and 18-25 urn long, basal cell abruptly truncated and apparently with a papillate depressed scar, apical cell elongated, subhyaline, tapering to 2-3 urn wide near the apex and thinner-walled, overall dimensions of the conidia 30-35(-45)x4-5-5um. Host: Lasioloma arachnoideum (Kremp.) R. Sant. (thallus) and a sterile indeterminate thallus are colonized and apparently damaged by this fungus. Several other foliicolous lichens are present on the leaf with the type of this species ( Gyalectidium aspidotum, Strigula nemathora Mont., Tricharia sp.) but these are not attacked by it. Distribution: Malaya. Known only from the type collection. Observations: This genus is perhaps, at least superficially, most similar to Dictyophrynella Bat. & Cavalcanti; its distinction from that genus has been discussed above (p. 214) so is not.
