Conidia hyaline, smooth-walled, aseptate,cylindrical, the apex and base rounded, with a prominent scar,contents granular or guttulate, (13–)13.5–16(–19) × (4.5–)5–5.5(–6) µm, mean ± SD = 14.8 ± 1.3 × 5.3 ± 0.3 µm, L/W ratio = 2.8,conidia of strain CBS 128528 longer, measuring (13–)14–19(–22.5)× (4–)4.5–5.5(–6) , mean ± SD = 16.7 ± 2.5 × 5.1 ± 0.5 µm, L/Wratio = 3.3.Culture characteristics: Colonies on SNA flat with entire margin,hyaline, pale cinnamon close to Anthriscus stem, on Anthriscusstem covered with orange to black conidiomata, filter paper partlyrosy buff, grey to black, covered with white mycelium and grey toblack conidiomata; reverse same colours, with black spots mainlyunder the filter paper, 21–21.5 mm in 7 d (32.5–33.5 mm in 10 d).Colonies on OA flat with entire margin, buff, towards the centregreenish olivaceous with orange to black conidiomata, aerialmycelium lacking; reverse buff, grey olivaceous to olivaceous greytowards the centre, 21.5 mm in 7 d (32–33.5 mm in 10 d). Conidiain mass orange.Material examined: Brazil, Sao Paulo, Bauru City, from fruit anthracnose ofPassiflora edulis f. flavicarpa, 1 June 2006, N. Massola and H.J.Tozze Jr., (CBSH-20697 holotype, culture ex-type CBS 128501 = ICMP 18607 = PAS12); SaoPaulo, Bauru City, from fruit of Passiflora edulis, 1 June 2006, N. Massola andH.J.Tozze Jr., CBS H-20696, culture CBS 128528 = ICMP 18606 = PAS10.Notes: There are four species in the C. boninense species complexknown to occur on Passiflora: C. brasiliense from Brazil (on fruits),C. colombiense from Colombia (on leaves), C. torulosum from NewZealand (on leaves) and C. karstii from Japan and Colombia (onleaves) and from Brazil (on fruits). According to Johnston & Jones(1997), C. gloeosporioides Group E (= C. novae-zelandiae) and C.gloeosporioides Group I (= C. constrictum) have also been isolatedfrom Passiflora, although this has not been confirmed by molecularmethods. Colletotrichum brasiliense and C. colombiense are at thisstage known only from Passiflora. Colletotrichum brasiliense is knownonly from Brazil where it causes anthracnose of yellow passion fruit(Passiflora edulis f. flavicarpa; Tozze et al. 2010). Colletotrichumbrasiliense is closely related to C. parsonsiae and C. hippeastri.Colletotrichum brasiliense is distinguished from these species withmost of the genes, including ITS, although the CHS-1 sequence ofone isolate was the same as that of C. parsonsii. Appressoria have alower L/W ratio (1.2) than other species in this group.There are numerous records of Colletotrichum, Gloeosporiumand Glomerella species on Passiflora (Farr & Rossman 2011).Two Colletotrichum and two Gloeosporium species have beenpreviously described from Passiflora. Gloeosporium passifloraeSpeg., described from Passiflora sp. in Argentina, forms longerconidia (20–30 × 5–6 µm) than any of the species in the C.boninense species complex known from Passiflora (Spegazzini1899). Conidia of C. passiflorae Siemaszko, which was describedon leaves of Passiflora edulis in Transcaucasia (today belonging toArmenia, Azerbaijan, and Georgia) are smaller, measuring 14–25× 4–6 µm (Siemaszko 1923). Most of the species treated herehave shorter conidia. Only conidia of C. brasiliense isolate CBSwww.studiesinmycology.org13
