18. Licea nigromarginata Nann. -Bremek., T.N. Lakh. & R.K. Chopra, in Lakhanpal, Nannenga-Bremekamp & Chopra, Proc. Kon. Ned. Akad. Wetensch., C. 93(3): 259 (1990) Figs. 15A–D

Sporophores sporocarpic, scattered, sessile. Sporocarps pulvinate, angular 0.3–0.6 mm diam. see from above, dull black. with a net of paler ridges. Peridium double, outer layer thick, gelatinous and pale, inner layer thick, membranous, smooth, brown; dehiscence into 5–12 platelets along preformed lines with dark perpendicular outgrowths (like sutures in Nannenga-Bremekamp´s drawing) in a darker zone at the margins ( Figs. 15 B – C ). Spores free, pale brown in mass, pale ochraceous yellow by TL, thick walled with thin pale area, globose or subglobose, 13–15(–16) µm diam., smooth. Protoplasmodium greyish white, turning brown and very dark brown.

Material examined: Isotypus. INDIA. Himachal Pradesh, Shimla, Summer Hill, 6-VIII-1981, in a moist chamber on bark (6-9 m up the trunk) from living Pinus wallichiana , leg. R.K. Chopra & T.N. Lakhanpal, 2237 RKC/LTN ( HPUB 13,237), NENB 13886 ( BR 5020071551626)! (only a slide) .

Habitat: on bark (6–9 m up the trunk) from living Pinus wallichiana .

Distribution: Known only from type territory (India).

Icon: Lakhanpal et al. (1990: 259, Figs. 6 A – C ).

Notes. The holotype of this species is kept in HPUB under the number 13237, but although requested it was not sent to us. However, the slide of the isotype was found in the collection of Nannenga-Bremekamp in Meise ( Fig. 15 A ), and we have used that for the images and description along with the detailed descriptions in Lakhanpal et al. (1990), and Nannenga-Bremekamp (2022).

The slide we examined is labelled “ L. morchelloides ” by hand, but on investigating the collection number and other details in the author’s notes we can confirm that this is a slide of the isotype of L. nigromarginata .
