Lophodermium rubrum P.R. Johnst. 1989

PDD 46154 - holotype (IMI - isotype).
Macroscopic appearance of ascocarps, and appearance in vertical section, is similar to that described for L. gramineum. Differs in that the vegetative mycelium within the host tissue, surrounding the ascocarps, is bright pinkish-red. Reddish tints also visible on surface of host leaf in areas where ascocarps present.

Paraphyses similar to L. gramineum. Asci 120-165 x 9.5-10.5 µm, subclavate, tapering to small, rounded apex, 8-spored. Ascospores 61-84 x 1.5-2.5 µm, 0-1 septate, with well-developed gelatinous sheath.

CHARACTERISTICS IN CULTURE: Ascospores germinated on agar within 48 hours. On OA colonies 4 cm diam. after 3 weeks, aerial mycelium low, felted, bright orange-red in colour, agar surface orange-brown, remaining sterile.

Northland.
Dead leaves of Cortaderia splendens.
Ab L. gramineo ascis 120-165 x 9.5-10.5 µm, mycelio roses differens.

ETYMOLOGY: rubrum = red; refers to colour of vegetative mycelium in the host tissue, and in culture.

NOTES: Distinguished from L. gramineum by colour of vegetative mycelium and by ascus and ascospore size. The pale, thin-walled cells lining the ascocarp opening become dark brown in colour in older ascocarps of L. rubrum, a feature not seen in L. gramineum.
